Fiberglide bearings

Fiberglide bearings are characterised by their high load-bearing capacity and dry-running properties. The bearings have a steel, bronze or stainless steel outer jacket and are available as a thin-walled model or thick-walled, turned model. The wearing surface is formed by a woven fibreglass and PTFE material that is glued to the inside. Fiberglide bearings are available as cylindrical bearings (both thin-walled and thick-walled), collar bearings (thick-walled only) and thrust washers. Different models such as spherical self-adjusting bearings are also possible.

THN has a limited standard range of Fiberglide bearings in various sizes and models. The standard range comprises mainly thin-walled, rolled (P-A1) bearings, but also a number of thick-walled, turned bushings with (P-A8) and without a collar (P-A7). There is also a standard range of thrust washers with steel jacket and lined on one side (P-A3), or with a wearing surface on both sides and an epoxy strengthening layer (P-C3).

The most important properties of Fiberglide bearings are:

High load-bearing capacity
Low friction coefficient (to 0.02)
No "stick-slip" effect
Good sound insulation
Extremely good corrosion resistance
Offers good resistance against shock loads
