Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 289 3013 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 Three-row Cylindrical Roller Slewing Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 289 3013 with a precision bore diameter (d) of 3246 mm, an outside diameter (D) of 3687 mm, and a nominal ring width (B) of 300 mm. This configuration yields an effective cross-sectional wall thickness of 220.5 mm and an envelope ratio (D/d) of 1.14, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 289 3013 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Every production batch of CHG Bearing 289 3013 Three-row Cylindrical Roller Slewing Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
