46276 560 mm 380 mm Frequently Asked Questions about 46276 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 46276 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46276 with a precision bore diameter (d) of 380 mm, an outside diameter (D) of 560 mm, and a nominal ring width (B) of 135 mm. This configuration yields an effective cross-sectional wall thickness of 90.0 mm and an envelope ratio (D/d) of 1.47, delivering compact rigidity for OEM machinery housings.
Absolutely. The CHG Bearing 46276 Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 46276, FAG 46276, NSK 46276. 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 46276 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.
