HM237545NA/HM237510D 288.925 mm 177.8 mm Frequently Asked Questions about HM237545NA/HM237510D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each HM237545NA/HM237510D 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 (177.8 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies HM237545NA/HM237510D with a precision bore diameter (d) of 177.8 mm, an outside diameter (D) of 288.925 mm, and a nominal ring width (B) of 142.875 mm. This configuration yields an effective cross-sectional wall thickness of 55.6 mm and an envelope ratio (D/d) of 1.62, delivering compact rigidity for OEM machinery housings.
When fitting HM237545NA/HM237510D over a 177.8 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.
Built for demanding industrial environments, the HM237545NA/HM237510D 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.
