NU334/P5 360 mm 170 mm 72 mm 220 mm Frequently Asked Questions about NU334/P5 Single 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 NU334/P5 with a precision bore diameter (d) of 170 mm, an outside diameter (D) of 360 mm, and a nominal ring width (B) of 72 mm. This configuration yields an effective cross-sectional wall thickness of 95.0 mm and an envelope ratio (D/d) of 2.12, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing NU334/P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (170 mm x 360 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
To ensure optimum performance of CHG Bearing NU334/P5 Single Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 170 mm bore. For the 360 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 NU334/P5 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.
