Frequently Asked Questions about 132.50.4500.04 Three-row Cylindrical Roller Slewing Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

The Open Type engineered for 132.50.4500.04 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.
Quality starts with raw material selection: CHG Bearing crafts 132.50.4500.04 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.
Model 132.50.4500.04 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.
For international ocean and air freight, CHG Bearing packs 132.50.4500.04 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
