FCD102146520 730 mm 510 mm 569 mm 520 mm Frequently Asked Questions about FCD102146520 Four-Row Cylindrical 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 FCD102146520 with a precision bore diameter (d) of 510 mm, an outside diameter (D) of 730 mm, and a nominal ring width (B) of 520 mm. This configuration yields an effective cross-sectional wall thickness of 110.0 mm and an envelope ratio (D/d) of 1.43, delivering compact rigidity for OEM machinery housings.
Model FCD102146520 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 510 mm) and steep thermal gradients between inner and outer rings.
To ensure optimum performance of CHG Bearing FCD102146520 Four-Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 510 mm bore. For the 730 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
The Open Type engineered for FCD102146520 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
