LM272235/210-SQ76P5 615.64 mm 457.2 mm N/A mm Frequently Asked Questions about LM272235/210-SQ76P5 Single Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each LM272235/210-SQ76P5 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 (457.2 mm bore side) ensures perfect planar contact without edge binding.
To extend the trouble-free lifespan of CHG Bearing LM272235/210-SQ76P5, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Model LM272235/210-SQ76P5 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 457.2 mm) and steep thermal gradients between inner and outer rings.
As standard production, CHG Bearing subjects LM272235/210-SQ76P5 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.
