7020 CD/HCP4ADBB 150 mm 100 mm 48 mm Frequently Asked Questions about 7020 CD/HCP4ADBB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 7020 CD/HCP4ADBB 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 (100 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 7020 CD/HCP4ADBB. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
The Open Type engineered for 7020 CD/HCP4ADBB 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.
When fitting 7020 CD/HCP4ADBB over a 100 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
