26HG60172X 300.02 mm 130 mm 172.65 mm Frequently Asked Questions about 26HG60172X Backing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 26HG60172X over a 130 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.
To ensure optimum performance of CHG Bearing 26HG60172X Backing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 130 mm bore. For the 300.02 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
As standard production, CHG Bearing subjects 26HG60172X 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 26HG60172X with a precision bore diameter (d) of 130 mm, an outside diameter (D) of 300.02 mm, and a nominal ring width (B) of 172.65 mm. This configuration yields an effective cross-sectional wall thickness of 85.0 mm and an envelope ratio (D/d) of 2.31, delivering compact rigidity for OEM machinery housings.
