130.40.3460.03 2550 mm 3212 mm 2860 mm 3694 mm 210 mm Frequently Asked Questions about 130.40.3460.03 Three-row Cylindrical Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 130.40.3460.03 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 (3212 mm bore side) ensures perfect planar contact without edge binding.
Beyond standard alloy steel, CHG Bearing can customize the 130.40.3460.03 Three-row Cylindrical Roller Slewing 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 130.40.3460.03 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (3212 mm x 3694 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The CHG Bearing 130.40.3460.03 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.
