Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 132.50.4500.03K3 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.
Absolutely. The CHG Bearing 132.50.4500.03K3 Three-row Cylindrical Roller Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 132.50.4500.03K3, FAG 132.50.4500.03K3, NSK 132.50.4500.03K3. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To match diverse operational dynamics, CHG Bearing supplies 132.50.4500.03K3 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.
Model 132.50.4500.03K3 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 4218 mm) and steep thermal gradients between inner and outer rings.
