SG, LFR..N and LFRI Track rollers

SG, LFR..N, and LFRI series track rollers with extended inner rings are used to guide the carriages and support the forces. SG sereies is with filling slots. LFR..N and LFRI series is without filling slots. These double row angular contact ball bearings have an outer ring with a gothic arch profile raceway, are sealed on both sides, and are greased for life. They can support axial loads from both sides and high radial forces due to the thick-walled outer ring.  Two points contact between gothic arch groove profile and track. Dimensional tolerance according to P6(ABEC-3). Radial run-out according to P5(ABEC-5). Internal radial clearance according to normal(CN). 

Solution advantage:

• Low noise, low vibration, highest lifetime
• Optimized sealing (no grease leakage, low friction, dust protection)
• Low acoustic noise
• High speed, high precision
• Direct contact with manufacturer and designers
• Short delivery time (stainless steel version on request)
