LM757049/LM757010 406.4 mm 304.8 mm N/A mm Frequently Asked Questions about LM757049/LM757010 Single Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the LM757049/LM757010 Single 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.
Model LM757049/LM757010 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 304.8 mm) and steep thermal gradients between inner and outer rings.
To ensure optimum performance of CHG Bearing LM757049/LM757010 Single Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 304.8 mm bore. For the 406.4 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Each LM757049/LM757010 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 (304.8 mm bore side) ensures perfect planar contact without edge binding.
