HKF075XP4 228.6 mm 190.5 mm 19.05 mm Frequently Asked Questions about HKF075XP4 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 HKF075XP4 with a precision bore diameter (d) of 190.5 mm, an outside diameter (D) of 228.6 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 1.2, delivering compact rigidity for OEM machinery housings.
In its sealed configuration (Open), CHG Bearing pre-charges HKF075XP4 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
The Open engineered for HKF075XP4 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Every production batch of CHG Bearing HKF075XP4 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.
