Description End caps

Version end cap full rubberised

End caps consist of a metal part (deep-drawn sheet) and an elastomer jacket on the outside. They are used to close openings and core drill holes and often replace end flanges or covers in gearbox construction. 

In accordance with DIN 3760, the end caps have an oversize on the outside diameter corresponding to the size, so that there is an interference fit for prefabricated bearing seat sealing ring bores.

Advantages of the end cap

  • Compensation of thermal expansion
  • no risk of fretting corrosion
  • effective protection against dirt ingress from the air side
  • can be mounted in split enclosures
  • Inexpensive static sealing



Partially rubberised end cap version

As an alternative to standard end caps, there are the partially rubberised end caps, which are only partially rubberised on the outer shell.

Special advantages of this new development

  • good static sealing (no pop-out effect)
  • friction fit to the housing bore
  • good heat flow
  • good heat flow

Additionally we offer a variety of special solutions, such as with a hole or a vent hole.
