7016 CD/P4ATBTB 125 mm 80 mm 66 mm Frequently Asked Questions about 7016 CD/P4ATBTB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7016 CD/P4ATBTB 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.
To ensure optimum performance of CHG Bearing 7016 CD/P4ATBTB Super-precision Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 80 mm bore. For the 125 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To safeguard CHG Bearing 7016 CD/P4ATBTB against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (80 mm x 125 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
When fitting 7016 CD/P4ATBTB over a 80 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.
