Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Single-sided or Double-sided Sealed), CHG Bearing pre-charges HRAU15008 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.
Beyond standard alloy steel, CHG Bearing can customize the HRAU15008 HRAU Series Crossed Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
To safeguard CHG Bearing HRAU15008 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (150 mm x 166 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
