iglidur® JVSM/JVSI - Clearance-free prestressed bearing

iglidur® JVSM and JVFM bearings are clearance-free in unloaded condition due to the axial and/or radial pretension. The iglidur® J material possesses extremely low coefficients of friction in dry operation and a very low stick-slip effect. Ideal for "anti-vibration mounting" of pedal bearings, etc.
