HWAA980HP4 141.2875 mm 127 mm 12.7 mm 136.11098 mm 132.15874 mm Frequently Asked Questions about HWAA980HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the HWAA980HP4 Super Duplex Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
To ensure optimum performance of CHG Bearing HWAA980HP4 Super Duplex Angular 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 141.2875 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To safeguard CHG Bearing HWAA980HP4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (127 mm x 141.2875 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
For international ocean and air freight, CHG Bearing packs HWAA980HP4 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.
