High precision track roller for idler wheel
THB Bearings

THB's double row high preicison LR seriers Track rollers with cylindrical or crowned outer ring for idler wheels.
1.LR rollers can be used in particular application where the friction should be reduced,such as in the heavy loads track or as idler wheel.
2.The outer diameter surface of rollers is shaped to the crowned runner surface with R500(suffix U),so make the stresses well when rollers working.
3.Rollers take the internal structure design of deep groove ball bearings or double row angular contact ball bearings and have a particularly thick-walled outer ring,so the rollers can accommodate higher loads.
4.Rollers are made of the 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.Rollers take the metal shield (suffix KDD) or rubble seal(suffix NPP) to prevent the dust.
THB also can provide the rollers with concentric or eccentric pivot.Some types of rollers can be made from the corrosion resistance stainless steel.

Characteristics of LR series track rollers:
1. Low resistance,long service life
2. Easy installation
3. Smooth running, minimum error

Application: idler wheel,slide block lifting,carriage motorization,etc.
