719/530P4 710 mm 530 mm 82 mm Frequently Asked Questions about 719/530P4 Angular Contact Ball Bearings（718 / 719 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 719/530P4 Angular Contact Ball Bearings（718 / 719 SERIES） under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 530 mm bore. For the 710 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 719/530P4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (530 mm x 710 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
