7001 CE/P4A 28 mm 12 mm 8 mm Frequently Asked Questions about 7001 CE/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 7001 CE/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.
For international ocean and air freight, CHG Bearing packs 7001 CE/P4A with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7001 CE/P4A with a precision bore diameter (d) of 12 mm, an outside diameter (D) of 28 mm, and a nominal ring width (B) of 8 mm. This configuration yields an effective cross-sectional wall thickness of 8.0 mm and an envelope ratio (D/d) of 2.33, delivering compact rigidity for OEM machinery housings.
Each 7001 CE/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 (12 mm bore side) ensures perfect planar contact without edge binding.
