HWA980HP4 141.2875 mm 127 mm 6.35 mm Frequently Asked Questions about HWA980HP4 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model HWA980HP4 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 127 mm) and steep thermal gradients between inner and outer rings.
Standard batches of CHG Bearing HWA980HP4 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.
The Open / Single-Sided Sealed / Double-Sided Sealed engineered for HWA980HP4 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.
Absolutely. The CHG Bearing HWA980HP4 Thin Section Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HWA980HP4, FAG HWA980HP4, NSK HWA980HP4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
