EE220975D/221575 400.05 mm 247.65 mm Frequently Asked Questions about EE220975D/221575 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of EE220975D/221575 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.
To ensure optimum performance of CHG Bearing EE220975D/221575 Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 247.65 mm bore. For the 400.05 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE220975D/221575 with a precision bore diameter (d) of 247.65 mm, an outside diameter (D) of 400.05 mm, and a nominal ring width (B) of 119.06 mm. This configuration yields an effective cross-sectional wall thickness of 76.2 mm and an envelope ratio (D/d) of 1.62, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing EE220975D/221575 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (247.65 mm x 400.05 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
