Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 787/700 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
To safeguard CHG Bearing 787/700 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (700 mm x 900 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Model 787/700 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 700 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing 787/700 Four-Point Contact Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 787/700, FAG 787/700, NSK 787/700. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
