023.30.800 898 mm 702 mm 124 mm 658 mm 942 mm Frequently Asked Questions about 023.30.800 Double-Row Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the 023.30.800 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.
When fitting 023.30.800 over a 658 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Model 023.30.800 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 658 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing 023.30.800 Double-Row Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 023.30.800, FAG 023.30.800, NSK 023.30.800. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
