HKF050XP4 165.1 mm 127 mm 19.05 mm Frequently Asked Questions about HKF050XP4 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open engineered for HKF050XP4 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.
To ensure optimum performance of CHG Bearing HKF050XP4 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 127 mm bore. For the 165.1 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Absolutely. The CHG Bearing HKF050XP4 Thin Section Four-Point Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HKF050XP4, FAG HKF050XP4, NSK HKF050XP4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each HKF050XP4 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (127 mm bore side) ensures perfect planar contact without edge binding.
