Double Side Sealed Angular Contact Ball Bearing 71912C P4 Shielded High Speed Motor Bearing

The 71912C double side sealed angular contact ball bearing is a sealed 15 degree C-series unit for high speed motors and spindle applications where contamination and grease loss are concerns. A 60 mm bore, 85 mm outside diameter and 13 mm width give it a basic dynamic load rating of 24.0 kN and a static rating of 22.8 kN. Factory filled grease is retained by seals on both faces, keeping the raceways clean of dust, coolant mist and fine chips. The bearing reaches 15000 RPM under grease lubrication, giving reliable, low maintenance running inside sealed spindle and motor assemblies.

• Double Side Sealing: Seals on both faces retain the factory grease charge and block dust, coolant mist and fine particles, extending service life in dirty environments.
• High Speed Sealed Duty: A 15 degree contact angle and low friction cage allow 15000 RPM grease speed even with seals fitted, rare in a sealed angular contact design.
• P4 Precision Grade: Tight dimensional and runout control keeps vibration low for smooth motor and spindle operation.
• Grease Retention: A controlled grease fill and seal lip design reduce re-lubrication needs, lowering maintenance cost on hard to reach assemblies.
• Strong Load Rating: A 24.0 kN dynamic rating and 22.8 kN static rating carry combined axial and radial load with margin.
• Rugged Steel Balls: Precision steel balls deliver high rigidity and reliable rolling contact for continuous motor duty.

The 71912C sealed bearing serves high speed electric motors, sealed spindle heads, blower and fan units, pumps and gearbox input shafts where dust or moisture would shorten bearing life. Because both faces are sealed and pre-greased, it suits assemblies that are difficult to re-lubricate or that operate in dusty workshops. Motor builders and pump manufacturers use it to simplify assembly and reduce field failures caused by contamination.

Sealed units are wrapped in anti-rust paper, cushioned with foam and packed in a labeled export carton that resists moisture during transit. Seal integrity is checked before packing so the grease charge stays intact until installation. Each batch is inspected for bore, runout, clearance, seal fit and running noise, with reports available on request. Preload, grease type and matched arrangements can be customized, and orders can be consolidated for economical shipping.
