1797/4014 4490 mm 4014 mm 206 mm 4411 mm 4080 mm Frequently Asked Questions about 1797/4014 Crossed Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 1797/4014 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 4014 mm) and steep thermal gradients between inner and outer rings.
For international ocean and air freight, CHG Bearing packs 1797/4014 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.
Quality starts with raw material selection: CHG Bearing crafts 1797/4014 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.
Sourcing 1797/4014 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Crossed Roller Slewing Bearings.
