QJ219M 170 mm 95 mm 32 mm Frequently Asked Questions about QJ219M Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing QJ219M 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for QJ219M, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Engineered according to international ISO boundary plans, CHG Bearing supplies QJ219M with a precision bore diameter (d) of 95 mm, an outside diameter (D) of 170 mm, and a nominal ring width (B) of 32 mm. This configuration yields an effective cross-sectional wall thickness of 37.5 mm and an envelope ratio (D/d) of 1.79, delivering compact rigidity for OEM machinery housings.
The Open Type engineered for QJ219M 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.
