4946X3D 329.5 mm 230 mm 80 mm Frequently Asked Questions about 4946X3D Double Row Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 4946X3D against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (230 mm x 329.5 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The CHG Bearing 4946X3D is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Absolutely. The CHG Bearing 4946X3D Double Row Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 4946X3D, FAG 4946X3D, NSK 4946X3D. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Beyond standard alloy steel, CHG Bearing can customize the 4946X3D Double Row Angular Contact Ball 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.
