719/500P4 670 mm 500 mm 78 mm Frequently Asked Questions about 719/500P4 Angular Contact Ball Bearings（718 / 719 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 719/500P4 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 500 mm) and steep thermal gradients between inner and outer rings.
To ensure optimum performance of CHG Bearing 719/500P4 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 500 mm bore. For the 670 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Yes, 100% of 719/500P4 Angular Contact Ball Bearings（718 / 719 SERIES） leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
When fitting 719/500P4 over a 500 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.
