7018 CE/HCP4ADGA 140 mm 90 mm 48 mm Frequently Asked Questions about 7018 CE/HCP4ADGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 7018 CE/HCP4ADGA 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7018 CE/HCP4ADGA with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Each 7018 CE/HCP4ADGA 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 (90 mm bore side) ensures perfect planar contact without edge binding.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7018 CE/HCP4ADGA. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
