Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts 020.60.4500 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.
The Open Type engineered for 020.60.4500 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
To match diverse operational dynamics, CHG Bearing supplies 020.60.4500 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 020.60.4500 with a precision bore diameter (d) of 4222 mm, an outside diameter (D) of 4778 mm, and a nominal ring width (B) of 226 mm. This configuration yields an effective cross-sectional wall thickness of 278.0 mm and an envelope ratio (D/d) of 1.13, delivering compact rigidity for OEM machinery housings.
