2787/1400K1 1715 mm 1400 mm 1660 mm 1460 mm 110 mm Frequently Asked Questions about 2787/1400K1 Four-Point Contact Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 2787/1400K1 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 2787/1400K1 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.
Absolutely. The CHG Bearing 2787/1400K1 Four-Point Contact Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 2787/1400K1, FAG 2787/1400K1, NSK 2787/1400K1. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Engineered according to international ISO boundary plans, CHG Bearing supplies 2787/1400K1 with a precision bore diameter (d) of 1400 mm, an outside diameter (D) of 1715 mm, and a nominal ring width (B) of 110 mm. This configuration yields an effective cross-sectional wall thickness of 157.5 mm and an envelope ratio (D/d) of 1.23, delivering compact rigidity for OEM machinery housings.
