96 mm 80 mm 8 mm HRA8008 Frequently Asked Questions about HRA8008 HRAU Series Crossed Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each HRA8008 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 (80 mm bore side) ensures perfect planar contact without edge binding.
Standard batches of CHG Bearing HRA8008 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Absolutely. The CHG Bearing HRA8008 HRAU Series Crossed Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HRA8008, FAG HRA8008, NSK HRA8008. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
When fitting HRA8008 over a 80 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.
