NU3222 200 mm 110 mm 69.8 mm 132.5 mm Frequently Asked Questions about NU3222 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the NU3222 Single Row Cylindrical Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU3222 with a precision bore diameter (d) of 110 mm, an outside diameter (D) of 200 mm, and a nominal ring width (B) of 69.8 mm. This configuration yields an effective cross-sectional wall thickness of 45.0 mm and an envelope ratio (D/d) of 1.82, delivering compact rigidity for OEM machinery housings.
The CHG Bearing NU3222 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
The Open Type engineered for NU3222 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.
