46*85 46 mm 85 mm Frequently Asked Questions about 46*85 Cylindrical Rollers
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46*85 with a precision bore diameter (d) of mm, an outside diameter (D) of mm, and a nominal ring width (B) of mm. This configuration yields an effective cross-sectional wall thickness of 0 mm and an envelope ratio (D/d) of 0, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 46*85 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces ( mm x mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing 46*85 Cylindrical Rollers is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 46*85, FAG 46*85, NSK 46*85. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To match diverse operational dynamics, CHG Bearing supplies 46*85 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.
