H-LINER S & S1 bushings

These bushings, manufactured from a friction liner applied on a glass fiber structure, have excellent friction properties and improved wear resistance without external lubrication even on high loads

Products Characteristics:

The woven material of H-LINER™ S/S1 is composed of a friction layer backed on a high mechanical resistance composite structure. The technical characteristics are much more higher than extruded plastics and don't require any greasing.

Mating shaft:

For optimal performance we recommend to use grinded pin with a roughness lower than Ra 0,4 μm and hardness higher than 400 HB. HEF DURFERRIT PEL™ OX pin are particularly appropriated to work against H-Liner® bushings.

Assembly instructions

H-Liner™ M bearings are best assembled by press fitting or by nitrogen mounting. (Other assembly techniques can also be used, ex: glue). For further information, please contact HEF DURFERRIT prior to use.
