Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies 024.25.560 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Engineered according to international ISO boundary plans, CHG Bearing supplies 024.25.560 with a precision bore diameter (d) of 444 mm, an outside diameter (D) of 676 mm, and a nominal ring width (B) of 106 mm. This configuration yields an effective cross-sectional wall thickness of 116.0 mm and an envelope ratio (D/d) of 1.52, delivering compact rigidity for OEM machinery housings.
Beyond standard alloy steel, CHG Bearing can customize the 024.25.560 Double-Row Ball Slewing Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
To ensure optimum performance of CHG Bearing 024.25.560 Double-Row Ball Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 444 mm bore. For the 676 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
