Project Description
LR Series Track Roller Bearings are with cylindrical or crowned outer ring, also called cam rollers, include single row deep groove ball bearings or double row angular contact ball bearings, and have an extended outer ring, so the rollers can accommodate higher loads.
The outer ring surface of LR Series Track Roller bearings can be cylindrical or arc grooved(crowned) with R500(suffix with U).
They are used in the guide rails or idler wheels to meet the particular application that the friction should be reduced.
- bearing material: chrome steel(GCr15/SAE52100)
- Seals: KDD(metal shields), NPP(rubber seals)
- KDD: metal shields with cylindrical outer ring
NPP: rubber seals with cylindrical outer ring - KDDU: metal shields with arc groove outer ring
NPPU: rubber seals with arc groove outer ring
