6905 42 mm 25 mm 9 mm Frequently Asked Questions about 6905 Metric Super-Thin Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 6905 with a precision bore diameter (d) of 25 mm, an outside diameter (D) of 42 mm, and a nominal ring width (B) of 9 mm. This configuration yields an effective cross-sectional wall thickness of 8.5 mm and an envelope ratio (D/d) of 1.68, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies 6905 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.
Absolutely. The CHG Bearing 6905 Metric Super-Thin Deep Groove Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 6905, FAG 6905, NSK 6905. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To ensure optimum performance of CHG Bearing 6905 Metric Super-Thin Deep Groove Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 25 mm bore. For the 42 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
