EE130889/131402D 355.6 mm 225.425 mm 158.75 mm Frequently Asked Questions about EE130889/131402D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing EE130889/131402D 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 Double Row Tapered Roller Bearings.
When fitting EE130889/131402D over a 225.425 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
As standard production, CHG Bearing subjects EE130889/131402D 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 EE130889/131402D with a precision bore diameter (d) of 225.425 mm, an outside diameter (D) of 355.6 mm, and a nominal ring width (B) of 158.75 mm. This configuration yields an effective cross-sectional wall thickness of 65.1 mm and an envelope ratio (D/d) of 1.58, delivering compact rigidity for OEM machinery housings.
