Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 71900 CD/HCP4A produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (10 mm bore side) ensures perfect planar contact without edge binding.
To match diverse operational dynamics, CHG Bearing supplies 71900 CD/HCP4A with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
The CHG Bearing 71900 CD/HCP4A 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71900 CD/HCP4A with a precision bore diameter (d) of 10 mm, an outside diameter (D) of 22 mm, and a nominal ring width (B) of 6 mm. This configuration yields an effective cross-sectional wall thickness of 6.0 mm and an envelope ratio (D/d) of 2.2, delivering compact rigidity for OEM machinery housings.
