HWAA1380HP4 147.6375 mm 127 mm 15.875 mm 140.28 mm 134.354 mm Frequently Asked Questions about HWAA1380HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting HWAA1380HP4 over a 127 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.
For international ocean and air freight, CHG Bearing packs HWAA1380HP4 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Yes, 100% of HWAA1380HP4 Super Duplex Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Each HWAA1380HP4 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.
