Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 29260 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 29260 with a precision bore diameter (d) of 300 mm, an outside diameter (D) of 353 mm, and a nominal ring width (B) of 420 mm. This configuration yields an effective cross-sectional wall thickness of 26.5 mm and an envelope ratio (D/d) of 1.18, delivering compact rigidity for OEM machinery housings.
The CHG Bearing 29260 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.
Sourcing 29260 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 Spherical Roller Thrust Bearings.
