C 6908 V CARB Full Complement Toroidal Roller Bearing 40x62x40mm

C6908V is a CARB self-aligning full complement single row cylindrical roller bearing, also called ring roller bearing, core full roller structure without retainer, model suffix V stands for full roller assembly design. Standard unified boundary dimension inner diameter d=40mm, outer diameter D=62mm, width B=40mm.

Unique curved roller + symmetrical arc raceway self-aligning structure, can simultaneously compensate shaft deflection, mounting parallelism deviation and thermal expansion axial elongation, solve jamming, abnormal wear and premature failure caused by installation misalignment and temperature deformation. Full roller layout maximizes roller quantity inside bearing, far higher radial load capacity than caged cylindrical roller bearings, suitable for low-speed heavy-duty continuous operation conditions.

All inner ring, outer ring and cylindrical rollers adopt fully quenched GCr15 bearing steel, ultra-precision mirror grinding curved raceway, stable rolling performance, strong wear resistance. Widely matched for printing press rollers, heavy conveyor rollers, paper making machinery, textile heavy calender equipment, lifting machinery and construction heavy-duty transmission equipment.
