EE275105/275156D 393.7 mm 266.7 mm Frequently Asked Questions about EE275105/275156D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing EE275105/275156D is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Every production batch of CHG Bearing EE275105/275156D Double Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
To ensure optimum performance of CHG Bearing EE275105/275156D Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 266.7 mm bore. For the 393.7 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 EE275105/275156D with a precision bore diameter (d) of 266.7 mm, an outside diameter (D) of 393.7 mm, and a nominal ring width (B) of 157.163 mm. This configuration yields an effective cross-sectional wall thickness of 63.5 mm and an envelope ratio (D/d) of 1.48, delivering compact rigidity for OEM machinery housings.
