Bearings for an extensive range of pumps

Bearings for pumps

We design and manufacture a full range of oil and grease free bearings for an extensive range of pumps. The elastomeric grade offers the best combination of rigidity/hardness and flexibility/elasticity accompanied by high abrasion resistance.

The thermoplastic grade is ideal for working at a higher temperature and pressure than the elastomeric grade and also has greater chemical resistance.

The benefits of our materials include:

  • Long useful life and lower maintenance costs
  • Ability to be started up dry
  • Low friction – NOT affected by the STICK-SLIP phenomenon
  • Easy to machine and install
  • Short delivery times for any size
  • Reduces starting torque
  • Materials certified to work in drinking water pumps
Elastomeric grades for pumps


Grado SXL


  • The preferred grade for starting up dry
  • Low coefficient of friction working dry: 0.10 – 0.20
  • Working pressure 10 MPa
  • Works dry or lubricated
  • High resistance to abrasion, impacts and vibrations
 Composite bearing reduces maintenance


  • Manufactured especially for use in very abrasive environments
  • More rigid and twice as abrasion resistant as rubber
  • Reduces maintenance
  • “Grease free” water lubrication
  • Easy to install
XL bearings


  • Long wear life
  • Low coefficient of friction
  • Good resistance to shock loads and vibrations
  • Optimum performance in applications with relatively clean fluids
PT80 bearing


  • Excellent mechanical properties (in water) at high temperatures
  • Ability to be started up dry
  • Long wear life
  • High resistance to abrasion
  • Low coefficient of friction
ThorPlas Blue bearings


  • Ability to start up dry
  • Works in water and chemicals up to temperatures of 80°C and dry up to 110°C
  • Working pressure 45 MPa
  • Very low wear in environments which are not very abrasive
  • Very low coefficient of friction
ThorPlas White certified bearings


  • NSF/ANSI 61 and WRAS certified
  • Suitable for drinking water
  • Very low wear
  • Very good capacity for working dry
  • Easy to machine
