  • Protect against diesel effect
  • Low maintenance costs
  • Easy installation

 The purpose of polymer bearings is to guide the piston and rod within cylindrical applications, absorbing any transverse forces which may occur.  They prevent metal-to-metal contact, optimizing the performance of the sealing system.

Bearings are needed to protect primary seal components and hardware so optimum sealing performance and service life can be achieved.

Designs

Four different types of bearing materials under the brand name Slydring® are available depending on application demands:

  • Turcon® PTFE based materials Highly wear-resistant, low-friction, specially modified for low to medium loads
  • Orkot® fabric composite materials for high loads and transverse forces.
  • Zurcon® high-modulus thermoplastic provides long service life in high loads and temperatures.
  • HiMod® high-modulus thermoplastic for use in extreme working conditions.

Please contact our sealing specialist to help determine which material would be ideal for your application.
