HM262749/HM262710 488.95 mm 346.075 mm N/A mm Frequently Asked Questions about HM262749/HM262710 Single Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the HM262749/HM262710 Single Row Tapered Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Engineered according to international ISO boundary plans, CHG Bearing supplies HM262749/HM262710 with a precision bore diameter (d) of 346.075 mm, an outside diameter (D) of 488.95 mm, and a nominal ring width (B) of N/A mm. This configuration yields an effective cross-sectional wall thickness of 0 mm and an envelope ratio (D/d) of 0, delivering compact rigidity for OEM machinery housings.
Each HM262749/HM262710 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 (346.075 mm bore side) ensures perfect planar contact without edge binding.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for HM262749/HM262710, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
