Find key technical answers regarding dimensions, specifications, and replacement options for this model.
For international ocean and air freight, CHG Bearing packs 011.40.1000.12K1 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.
Sourcing 011.40.1000.12K1 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 Four-Point Contact Ball Slewing Bearings.
Each 011.40.1000.12K1 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (878 mm bore side) ensures perfect planar contact without edge binding.
Quality starts with raw material selection: CHG Bearing crafts 011.40.1000.12K1 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.
