The track roller bearings are made of
high-quality bearing steel, processed by heat treatment and precision grind,
and are filled with a long service life, high-grade and multi-purposes grease.
The track roller bearings mount the metal shield (KDD) or rubble seal (NPP) to
prevent the dust. We also can provide the rollers with concentric or eccentric
pivot. Some types of the rollers can be made from the corrosion resistance
stainless steel.
For series LFR rollers, the surface profile of the outer ring is designed as
the GOTHIC ARCH. When running, there are two contact points with an angle 60
degrees between the roller and track. So the friction resistance is low and the
load is in equality, thus avoiding the stresses concentration and edge effect
caused by the error from installation and manufacture, endowing the track
roller bearings system the characteristics of high speed, low energy
consumption, long service life and minimum noise level.
