Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 023.40.1250 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 (1074 mm bore side) ensures perfect planar contact without edge binding.
Built for demanding industrial environments, the 023.40.1250 Double-Row Ball Slewing Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 023.40.1250 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
Sourcing 023.40.1250 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 Double-Row Ball Slewing Bearings.
