M238849D/M238810 269.875 mm 187.325 mm Frequently Asked Questions about M238849D/M238810 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies M238849D/M238810 with a precision bore diameter (d) of 187.325 mm, an outside diameter (D) of 269.875 mm, and a nominal ring width (B) of 101.6 mm. This configuration yields an effective cross-sectional wall thickness of 41.3 mm and an envelope ratio (D/d) of 1.44, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing M238849D/M238810 Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 187.325 mm bore. For the 269.875 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Built for demanding industrial environments, the M238849D/M238810 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.
Model M238849D/M238810 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 187.325 mm) and steep thermal gradients between inner and outer rings.
