FC5480220 400 mm 270 mm 305 mm 220 mm Frequently Asked Questions about FC5480220 Four-Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing FC5480220 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (270 mm x 400 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Each FC5480220 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 (270 mm bore side) ensures perfect planar contact without edge binding.
To ensure optimum performance of CHG Bearing FC5480220 Four-Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 270 mm bore. For the 400 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Absolutely. The CHG Bearing FC5480220 Four-Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF FC5480220, FAG FC5480220, NSK FC5480220. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
