46234A 260 mm 170 mm Frequently Asked Questions about 46234A Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of 46234A Double Row Tapered Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Built for demanding industrial environments, the 46234A Double Row Tapered Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46234A with a precision bore diameter (d) of 170 mm, an outside diameter (D) of 260 mm, and a nominal ring width (B) of 84 mm. This configuration yields an effective cross-sectional wall thickness of 45.0 mm and an envelope ratio (D/d) of 1.53, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 46234A Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 170 mm bore. For the 260 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
