L163149/110CD/XA 444.5 mm 355.6 mm Frequently Asked Questions about L163149/110CD/XA 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 L163149/110CD/XA Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 355.6 mm bore. For the 444.5 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Model L163149/110CD/XA 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 355.6 mm) and steep thermal gradients between inner and outer rings.
Absolutely.
