S7008 FEGA/HCP4A 68 mm 40 mm 15 mm Frequently Asked Questions about S7008 FEGA/HCP4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7008 FEGA/HCP4A with a precision bore diameter (d) of 40 mm, an outside diameter (D) of 68 mm, and a nominal ring width (B) of 15 mm. This configuration yields an effective cross-sectional wall thickness of 14.0 mm and an envelope ratio (D/d) of 1.7, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs S7008 FEGA/HCP4A 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.
Each S7008 FEGA/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 (40 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing S7008 FEGA/HCP4A against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (40 mm x 68 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
