7012 ACEGA/HCP4AH1 95 mm 60 mm 18 mm Frequently Asked Questions about 7012 ACEGA/HCP4AH1 Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 7012 ACEGA/HCP4AH1 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 60 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7012 ACEGA/HCP4AH1 with a precision bore diameter (d) of 60 mm, an outside diameter (D) of 95 mm, and a nominal ring width (B) of 18 mm. This configuration yields an effective cross-sectional wall thickness of 17.5 mm and an envelope ratio (D/d) of 1.58, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies 7012 ACEGA/HCP4AH1 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 Open Type engineered for 7012 ACEGA/HCP4AH1 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.
