TR21-2 Single Row Separable Tapered Roller Bearing 105x125x10.3/12.5mm Compact Industrial Gearbox Equipment

TR21-2 is compact single row separable tapered roller bearing, standard dimension 105×125×10.3/12.5mm. Separable inner cone and outer cup allow independent assembly, disassembly and clearance fine adjustment. Tapered raceway and crowned rollers simultaneously bear combined radial load and one-way axial thrust, compact thin-width design saves limited axial installation space. Stable operation under medium load and slight vibration, widely applied in small industrial gearboxes, light transport equipment, textile transmission shafts and general mechanical rotary assembliesMade-in-Ch....
