HM231132/HM231116D 241.3 mm 139.7 mm Frequently Asked Questions about HM231132/HM231116D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting HM231132/HM231116D over a 139.7 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
As standard production, CHG Bearing subjects HM231132/HM231116D 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.
Absolutely. The CHG Bearing HM231132/HM231116D Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HM231132/HM231116D, FAG HM231132/HM231116D, NSK HM231132/HM231116D. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each HM231132/HM231116D 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 (139.7 mm bore side) ensures perfect planar contact without edge binding.
