HKD120XP0 330.2 mm 304.8 mm 12.7 mm Frequently Asked Questions about HKD120XP0 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKD120XP0 with a precision bore diameter (d) of 304.8 mm, an outside diameter (D) of 330.2 mm, and a nominal ring width (B) of 12.7 mm. This configuration yields an effective cross-sectional wall thickness of 12.7 mm and an envelope ratio (D/d) of 1.08, delivering compact rigidity for OEM machinery housings.
The CHG Bearing HKD120XP0 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Sourcing HKD120XP0 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.
To ensure optimum performance of CHG Bearing HKD120XP0 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 304.8 mm bore. For the 330.2 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
