Frequently Asked Questions about S7008 CEGA/HCP4A Super-precision Angular Contact Ball Bearings

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

Model S7008 CEGA/HCP4A is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 40 mm) and steep thermal gradients between inner and outer rings.
The Non-contact Seal engineered for S7008 CEGA/HCP4A 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.
Standard batches of CHG Bearing S7008 CEGA/HCP4A conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Yes, 100% of S7008 CEGA/HCP4A Super-precision Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
