HJG180XP0 508 mm 457.2 mm 25.4 mm Frequently Asked Questions about HJG180XP0 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting HJG180XP0 over a 457.2 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.
Every production batch of CHG Bearing HJG180XP0 Thin Section Four-Point Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Engineered according to international ISO boundary plans, CHG Bearing supplies HJG180XP0 with a precision bore diameter (d) of 457.2 mm, an outside diameter (D) of 508 mm, and a nominal ring width (B) of 25.4 mm. This configuration yields an effective cross-sectional wall thickness of 25.4 mm and an envelope ratio (D/d) of 1.11, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing HJG180XP0 Thin Section Four-Point Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 457.2 mm bore. For the 508 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
