NCF2972V 480 mm 72 mm 360 mm Frequently Asked Questions about NCF2972V Full Complement Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing NCF2972V against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (360 mm x 480 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Model NCF2972V 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 360 mm) and steep thermal gradients between inner and outer rings.
To ensure optimum performance of CHG Bearing NCF2972V Full Complement Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 360 mm bore. For the 480 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 NCF2972V 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.
