HKF140XP4 393.7 mm 355.6 mm 19.05 mm Frequently Asked Questions about HKF140XP4 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing HKF140XP4 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 355.6 mm bore. For the 393.7 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Sourcing HKF140XP4 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Thin Section Four-Point Contact Ball Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKF140XP4 with a precision bore diameter (d) of 355.6 mm, an outside diameter (D) of 393.7 mm, and a nominal ring width (B) of 19.05 mm. This configuration yields an effective cross-sectional wall thickness of 19.0 mm and an envelope ratio (D/d) of 1.11, delivering compact rigidity for OEM machinery housings.
When fitting HKF140XP4 over a 355.6 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.
