NNU4952/W33P5 360 mm 260 mm 289 mm 100 mm Frequently Asked Questions about NNU4952/W33P5 Double Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing NNU4952/W33P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (260 mm x 360 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
To match diverse operational dynamics, CHG Bearing supplies NNU4952/W33P5 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
To ensure optimum performance of CHG Bearing NNU4952/W33P5 Double Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 260 mm bore. For the 360 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Sourcing NNU4952/W33P5 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Double Row Cylindrical Roller Bearings.
