HKC040CP4 120.65 mm 101.6 mm 9.525 mm Frequently Asked Questions about HKC040CP4 Thin Section Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing HKC040CP4 Thin Section Deep Groove Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
As standard production, CHG Bearing subjects HKC040CP4 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Beyond standard alloy steel, CHG Bearing can customize the HKC040CP4 Thin Section Deep Groove Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Each HKC040CP4 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 (101.6 mm bore side) ensures perfect planar contact without edge binding.
