Frequently Asked Questions about S7009 CDGA/P4A Super-precision Angular Contact Ball Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

To match diverse operational dynamics, CHG Bearing supplies S7009 CDGA/P4A 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 Non-contact Seal engineered for S7009 CDGA/P4A 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.
Each S7009 CDGA/P4A 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 (45 mm bore side) ensures perfect planar contact without edge binding.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for S7009 CDGA/P4A, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
