LM272249/LM272210 615.95 mm 482.6 mm N/A mm Frequently Asked Questions about LM272249/LM272210 Single Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing LM272249/LM272210 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 Single Row Tapered Roller Bearings.
To ensure optimum performance of CHG Bearing LM272249/LM272210 Single Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 482.6 mm bore. For the 615.95 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Each LM272249/LM272210 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 (482.6 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing LM272249/LM272210 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (482.6 mm x 615.95 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
