021.40.1800 1976 mm 1624 mm 160 mm 1924 mm 1676 mm Frequently Asked Questions about 021.40.1800 Double-Row Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 021.40.1800 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 (1624 mm bore side) ensures perfect planar contact without edge binding.
Sourcing 021.40.1800 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.
Model 021.40.1800 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 1624 mm) and steep thermal gradients between inner and outer rings.
Standard batches of CHG Bearing 021.40.1800 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.
