HM926749/HM926710D 228.6 mm 127.792 mm Frequently Asked Questions about HM926749/HM926710D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing HM926749/HM926710D 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.
Beyond standard alloy steel, CHG Bearing can customize the HM926749/HM926710D Double 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 HM926749/HM926710D with a precision bore diameter (d) of 127.792 mm, an outside diameter (D) of 228.6 mm, and a nominal ring width (B) of 115.888 mm. This configuration yields an effective cross-sectional wall thickness of 50.4 mm and an envelope ratio (D/d) of 1.79, delivering compact rigidity for OEM machinery housings.
Model HM926749/HM926710D is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 127.792 mm) and steep thermal gradients between inner and outer rings.
