Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies 130.45.2800.03K with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 130.45.2800.03K, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Quality starts with raw material selection: CHG Bearing crafts 130.45.2800.03K inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Beyond standard alloy steel, CHG Bearing can customize the 130.45.2800.03K 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.
