46236A 280 mm 180 mm Frequently Asked Questions about 46236A Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 46236A over a 180 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.
Sourcing 46236A directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Double Row Tapered Roller Bearings.
To ensure optimum performance of CHG Bearing 46236A Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 180 mm bore. For the 280 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Each 46236A 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 (180 mm bore side) ensures perfect planar contact without edge binding.
