HM252348DW/HM252310/HM252310CDP5 422.275 mm 260.35 mm 314.325 mm Frequently Asked Questions about HM252348DW/HM252310/HM252310CDP5 Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing HM252348DW/HM252310/HM252310CDP5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (260.35 mm x 422.275 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
To ensure optimum performance of CHG Bearing HM252348DW/HM252310/HM252310CDP5 Four-Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 260.35 mm bore. For the 422.275 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
For international ocean and air freight, CHG Bearing packs HM252348DW/HM252310/HM252310CDP5 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Each HM252348DW/HM252310/HM252310CDP5 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 (260.35 mm bore side) ensures perfect planar contact without edge binding.
