Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 170FC118650/P5 with a precision bore diameter (d) of 850 mm, an outside diameter (D) of 1180 mm, and a nominal ring width (B) of 650 mm. This configuration yields an effective cross-sectional wall thickness of 165.0 mm and an envelope ratio (D/d) of 1.39, delivering compact rigidity for OEM machinery housings.
Each 170FC118650/P5 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (850 mm bore side) ensures perfect planar contact without edge binding.
To ensure optimum performance of CHG Bearing 170FC118650/P5 Four-Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 850 mm bore. For the 1180 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 170FC118650/P5, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
