EE126097/126149D 380.898 mm 244.475 mm 171.45 mm Frequently Asked Questions about EE126097/126149D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing EE126097/126149D Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 244.475 mm bore. For the 380.898 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 EE126097/126149D with a precision bore diameter (d) of 244.475 mm, an outside diameter (D) of 380.898 mm, and a nominal ring width (B) of 171.45 mm. This configuration yields an effective cross-sectional wall thickness of 68.2 mm and an envelope ratio (D/d) of 1.56, delivering compact rigidity for OEM machinery housings.
The CHG Bearing EE126097/126149D 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.
Built for demanding industrial environments, the EE126097/126149D 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.
