Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 82*126.22 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 Tapered Rollers.
Engineered according to international ISO boundary plans, CHG Bearing supplies 82*126.22 with a precision bore diameter (d) of mm, an outside diameter (D) of mm, and a nominal ring width (B) of 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 82*126.22, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Model 82*126.22 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 mm) and steep thermal gradients between inner and outer rings.
