HM252344D/HM252315 431.724 mm 254 mm Frequently Asked Questions about HM252344D/HM252315 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing HM252344D/HM252315 Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HM252344D/HM252315, FAG HM252344D/HM252315, NSK HM252344D/HM252315. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
As standard production, CHG Bearing subjects HM252344D/HM252315 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Each HM252344D/HM252315 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.
Built for demanding industrial environments, the HM252344D/HM252315 Double Row Tapered 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.
