Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 206KV2857 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 Four-Row Tapered Roller Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 206KV2857 with a precision bore diameter (d) of 206.375 mm, an outside diameter (D) of 282.575 mm, and a nominal ring width (B) of 210 mm. This configuration yields an effective cross-sectional wall thickness of 38.1 mm and an envelope ratio (D/d) of 1.37, delivering compact rigidity for OEM machinery housings.
The CHG Bearing 206KV2857 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 206KV2857 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.
