Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing 011.45.1400.12K conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
For international ocean and air freight, CHG Bearing packs 011.45.1400.12K 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.
Beyond standard alloy steel, CHG Bearing can customize the 011.45.1400.12K Four-Point Contact Ball Slewing Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Engineered according to international ISO boundary plans, CHG Bearing supplies 011.45.1400.12K with a precision bore diameter (d) of 1260 mm, an outside diameter (D) of 1540 mm, and a nominal ring width (B) of 110 mm. This configuration yields an effective cross-sectional wall thickness of 140.0 mm and an envelope ratio (D/d) of 1.22, delivering compact rigidity for OEM machinery housings.
