K-HH953749/710 533.4 mm 254 mm N/A mm Frequently Asked Questions about K-HH953749/710 Single Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing K-HH953749/710 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (254 mm x 533.4 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 K-HH953749/710 Single Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 254 mm bore. For the 533.4 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Each K-HH953749/710 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (254 mm bore side) ensures perfect planar contact without edge binding.
