Our Ring Side Flatness Gage quantifies the side flatness of rectangular and Keystone compression rings, directly tied to how well those rings control blowby and oil consumption. Instead of relying on visual checks or indirect indicators, you obtain hard measurements of side face accuracy before rings ever see an engine.

The system is well-developed, with documented procedures that standardize how flatness is measured, recorded, and interpreted across batches and suppliers. Developed with internal CKE funds, it reflects decades of compression ring experience distilled into a practical metrology tool.

Used in incoming inspection, process development, or R&D, the gage exposes small deviations that can compromise ring seating, twist behavior, and gas sealing. The result is more consistent ring performance, fewer surprise oil control issues, and a stronger correlation between design intent and hardware behavior.

The Digital Light Gage measures the light tightness of piston rings, giving you a direct indicator of how well a ring conforms to ideal and non-round cylinder bores. By mapping transmitted light around the circumference, the instrument reveals gaps and high spots that conventional dimensional checks miss.

This conformability information is especially valuable when validating new ring profiles, tensions, and materials against distorted or honed bores. The gage is routinely used to benchmark ring conformability models, allowing you to close the loop between simulation and physical behavior.

For manufacturers, builders, and test labs, the benefit is clear: earlier detection of marginal ring-bore contact, improved prediction of blowby and oil control, and tighter control of ring manufacturing processes aligned with real-world bore conditions.

The Piston Ring Profile Gage captures the true face profile of piston rings with the resolution needed to tune oil control and friction, rather than just verifying basic dimensions. By quantifying the exact crown, taper, and relief, it gives designers and manufacturing engineers the data required to align as-built geometry with design intent.

Measured profiles can be fed into ring/bore contact and lubrication models to predict film thickness, contact pressure distribution, and potential for hydrodynamic lift. That, in turn, guides optimization of ring face geometry for lower oil consumption and reduced mechanical losses, without sacrificing durability.

In production or development environments, the gage helps correlate microscopic shape variations with engine-level behavior, enabling process corrections before they show up as warranty or test-cell problems.

Our Tangential Tension Gage - LT quantifies piston ring tangential tension with precision and repeatability that traditional fixtures rarely provide. Accurate tension data is essential for balancing ring conformability, friction, and stable sealing across the engine's operating envelope.

The system measures, stores, and displays tension values for each ring, making it straightforward to track manufacturing trends, verify supplier compliance, and sort rings for specialized applications. Manufacturers, engine builders, and test labs use these measurements to link tension windows to blowby, oil control, and wear outcomes.

By turning tangential load into a controlled, monitored parameter instead of an assumed property, you can reduce friction without drifting into loss of seal, and support data-driven ring pack optimization across gasoline, diesel, and specialty programs.

The Keystone Width/Angle Gage provides accurate measurement of Keystone ring angle and thickness in accordance with SAE HS‑2200, giving piston ring manufacturers a reliable way to control this critical geometry. Small deviations in angle or width can alter ring motion, groove contact, and carbon-shedding behavior.

By integrating this gage into setup and ongoing operation, production teams can verify tooling, monitor drift, and document that rings meet specified tolerances. That level of control reduces the risk of ring sticking, uncontrolled blowby, or abnormal groove wear in the field.

For development programs, the gage enables systematic sweeps of Keystone geometry, letting you quantify how angle and thickness shifts influence sealing performance and deposit management before committing to hard tooling changes.

Our BEE 3‑D Bore Evaluation Equipment quantifies circumferential and axial cylinder bore geometry using high-resolution 3D measurement, giving you a detailed picture of how the bore really looks, not just how it was specified. The system reports roundness, taper, waviness, and distortion features that strongly influence ring behavior.

A touch-screen interface, color 3D display, and tiltable views make it easy to interrogate localized geometry, while Fourier-based analysis converts complex shapes into interpretable harmonic content. This is particularly valuable when correlating machining processes, clamping strategies, and block designs with actual bore form.

By connecting these geometric fingerprints to blowby, oil control, and wear results, you can refine honing and machining parameters, adjust design features, and validate blocks more effectively than with traditional gauge-only checks.

The SEE 3‑D Surface Evaluation Equipment delivers true 3D surface finish information for cylinder bores, where conventional 2D parameters often fall short. It quantifies surface volume available for lubricant retention and the effective area available for load-bearing mating contact.

Those metrics can be imported directly into wear and lubrication models, allowing you to simulate how different finishes will behave under real engine conditions. You can, for example, compare plateau honing strategies or abrasive sequences by their expected impact on film support, scuff resistance, and run-in behavior.

With SEE 3‑D, surface engineering becomes a controlled variable rather than an art form. You gain a clear link between process settings, measured 3D texture, and long-term ring/liner performance on test stands and in the field.

The SEE 3‑D Fixture and Analyzer is our dedicated 3D imaging platform for cylinder bore surfaces, designed to capture and interpret more than 30 distinct surface characteristics in one cohesive data set. It goes beyond simple Ra/Rz values to characterize plateau structure, valley networks, and directional features that affect lubrication and wear.

By visualizing and quantifying these parameters, you can understand how honing patterns, abrasive selections, and process variations change the functional surface seen by the ring pack. The analyzer's high-resolution output supports direct correlation with friction, scuff, and oil consumption data from engine or bench testing.

For OEMs and R&D groups, this fixture becomes a central tool for diagnosing problematic finishes, qualifying new processes, and building a library of surface states that consistently deliver targeted performance.

The BEE 3‑D Cylinder Bore Geometry Gage provides micron-level insight into bore roundness, cylindricity, and straightness using 3D imaging with sensor accuracy under 2 microns. That level of detail is essential when ring packs are designed around tight conformability and low oil consumption targets.

The instrument captures axial and circumferential form, revealing distortions from head bolt loading, thermal gradients, or machining artifacts that traditional gauges cannot fully describe. Engineers can view these distortions in 3D, extract harmonic content, and relate specific geometric features to measured blowby and wear.

In quality and development environments, the gage supports both process control and design validation, ensuring that bore geometry consistently matches the assumptions embedded in ring-bore simulations and durability targets.

Our Custom Precision Gages and Bench Test Fixtures are built to answer specific questions about your cylinder kit components, rather than forcing you to adapt to generic instrumentation. We design and supply gages for rings, pistons, and bores, as well as dedicated fixtures for wear, friction, and oil control studies.

Each tool is engineered around the geometry, tolerances, and performance metrics that matter for your platform, whether you are an engine builder, OEM, or component supplier. Designs draw on the same expertise behind our PROMPT modeling, SEE 3‑D, and BEE 3‑D systems, so measurement outputs can flow directly into your analysis workflows.

The result is permanent lab or production assets that reduce measurement uncertainty, speed up root-cause investigations, and provide consistent data for decision-making across development and series production.

The PROMPT Cylinder Kit Model is our primary analytical tool for predicting how piston, ring pack, and cylinder bore design choices will influence oil consumption, blowby, and friction before metal is cut. PROMPT evaluates the combined effect of ring geometry, tension, groove details, bore form, and operating conditions using a physics-based framework.

Engineers use PROMPT to compare design variants, assess sensitivity to dimensional tolerances, and explore trade-offs between sealing efficiency and mechanical losses. Inputs can be derived from our precision gages and 3D bore measurements, ensuring that simulation reflects actual manufacturing capability.

By shifting much of the iteration from test cells to the analytical domain, PROMPT helps shorten development cycles, reduce prototype builds, and lower the risk of late-stage ring pack changes that impact cost and timing.

The PROMPT Ring Conformability Model focuses specifically on how piston ring design and materials interact with real cylinder bore geometry, including the void area between the ring face and bore surface. It quantifies how rings bend, twist, and seat under gas load and tension across distorted, honed, or thermally affected bores.

By resolving local contact pressures and gaps, the model indicates where blowby paths may open, where oil films may be too thin or too thick, and how design changes in profile, back angle, or tension will alter those behaviors. Bore shape inputs can be pulled directly from BEE 3‑D measurements for high fidelity.

This level of detail lets you refine ring designs with confidence, targeting specific distortions or finish states rather than relying on generic conformability assumptions.

Our Proprietary Cylinder Kit Software forms the backbone of how we analyze and model engine cylinder kit performance, integrating geometry, material, and operating data into actionable predictions. Built around decades of sealing and tribology work, it goes beyond generic CAE packages that treat the ring pack as a simplified boundary condition.

The platform connects inputs from PROMPT models, precision gages, and 3D bore and surface measurements to evaluate blowby behavior, oil consumption tendencies, friction contributions, and wear risks. This unified environment allows consistent assumptions and parameter sets across different studies.

For OEMs and advanced R&D groups, the software provides a structured way to manage cylinder kit design iterations, calibrate models against test results, and document the engineering basis for key sealing and lubrication decisions.
