HWA1349HP4 98.425 mm 77.7875 mm 7.937 mm Frequently Asked Questions about HWA1349HP4 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each HWA1349HP4 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 (77.7875 mm bore side) ensures perfect planar contact without edge binding.
In its sealed configuration (Open / Single-Sided Sealed / Double-Sided Sealed), CHG Bearing pre-charges HWA1349HP4 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
As standard production, CHG Bearing subjects HWA1349HP4 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Absolutely. The CHG Bearing HWA1349HP4 Thin Section Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HWA1349HP4, FAG HWA1349HP4, NSK HWA1349HP4.
