013.45.1400.12K 1540 mm 1260 mm 1487 mm 1313 mm 110 mm Frequently Asked Questions about 013.45.1400.12K Four-Point Contact Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 013.45.1400.12K 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 1260 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing 013.45.1400.12K Four-Point Contact Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 013.45.1400.12K, FAG 013.45.1400.12K, NSK 013.45.1400.12K. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
The Open Type engineered for 013.45.1400.12K by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Standard batches of CHG Bearing 013.45.1400.12K 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.
