NNU4924/W33-2P5 165 mm 120 mm 133.5 mm 45 mm Frequently Asked Questions about NNU4924/W33-2P5 Double Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the NNU4924/W33-2P5 Double Row Cylindrical Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
To safeguard CHG Bearing NNU4924/W33-2P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (120 mm x 165 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
To ensure optimum performance of CHG Bearing NNU4924/W33-2P5 Double Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 120 mm bore. For the 165 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
