QJF1960MX 419 mm 300 mm 60 mm Frequently Asked Questions about QJF1960MX Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing QJF1960MX Four-Point Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF QJF1960MX, FAG QJF1960MX, NSK QJF1960MX. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each QJF1960MX 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 (300 mm bore side) ensures perfect planar contact without edge binding.
To match diverse operational dynamics, CHG Bearing supplies QJF1960MX with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
The Open Type engineered for QJF1960MX 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.
