Description

Product description
The Radial Oil Seal Type RT is a rotary shaft seal with a fabric-reinforced outer diameter and an inserted tension spring. It follows a design similar to the RS type while adding an additional dust lip for applications with high external dust exposure. The RT design is particularly suitable for large diameters and facilitates easy assembly. Slotted designs or lubrication grooves can be supplied on request.

Usage details
Designed for rotating shafts in housings operating without pressure or with minimal pressure fluctuations. Standard elastomers: NBR and FKM. Other materials available on request.

Fields of application
  • static
  • dynamic
  • single acting
  • double acting
  • linear
  • rotating
  • oscillating

Main use
Unpressurized sealing for rotating shafts
