End Cap CS-10

Construction and design of the CS-10 end cap

Typical applications and why the CS-10 is suitable

CS-10 end caps are widely used in bearing housings, gearboxes, transmissions, motor reducers, and pump housings. They are ideal for sealing unused shaft openings or inspection bores. In bearing blocks, for example, they are used to completely close the side without a shaft, keeping grease inside and contamination out.
The end cap CS-10 is particularly suitable for these applications because it provides a fully closed seal without complex installation or additional components. The combination of a rigid metal core and a flexible sealing layer makes the end cap resistant to vibrations and slight thermal expansion, while remaining leak-free at low or no pressure. This makes the CS-10 type a logical alternative to cover plates or flanges in compact designs.

Material selection: properties, advantages, and limitations

The CS-10 end cap is available with different elastomer qualities, selected according to temperature, media, and environmental conditions.

FKM (fluoroelastomer)

FKM is used when higher temperatures, synthetic oils, fuels, or chemical media are involved. This material provides excellent thermal and chemical resistance and shows minimal ageing. A disadvantage of FKM is its reduced flexibility at low temperatures and its generally higher cost.
The choice between NBR and FKM is determined by the operating temperature, the medium to be sealed, and the desired service life of the seal.

Selecting the right CS-10 end cap: dimensions, standards, and tolerances

When selecting the correct CS-10 end cap, bore diameter, installation depth, and material choice are decisive. The outer diameter of the end cap must exactly match the bore into which it is press-fitted. For a reliable press fit, a bore with ISO tolerance H8 is recommended.
The height of the end cap must fit within the available installation space and provide sufficient axial support. Many CS-10 end caps are dimensionally aligned with standard oil seal sizes, allowing easy use in existing designs.
In addition, the selected elastomer must be suitable for the temperature, the medium, and the environmental conditions. Since the end cap CS-10 is a static seal, it is not suitable for applications involving rotation or pressure build-up; this should be taken into account during the design phase.

Cross Reference

In summary, the CS-10 End Cap is a reliable sealing solution that provides secure closure and effective sealing for bores, bearings, and shaft feedthroughs. Its utilization of highly resistant materials, wide temperature range, and customizable design options make it an ideal choice for various applications. Whether it's sealing transmissions, bearing blocks, split housings, or light metal housings, the CS-10 ensures reliable performance and protects against leaks and contamination. Trust in the CS-10 End Cap for secure closure and superior sealing performance in your applications.
