46334 280 mm 170 mm Frequently Asked Questions about 46334 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 46334 Double Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
To match diverse operational dynamics, CHG Bearing supplies 46334 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 46334 with a precision bore diameter (d) of 170 mm, an outside diameter (D) of 280 mm, and a nominal ring width (B) of 88 mm. This configuration yields an effective cross-sectional wall thickness of 55.0 mm and an envelope ratio (D/d) of 1.65, delivering compact rigidity for OEM machinery housings.
To extend the trouble-free lifespan of CHG Bearing 46334, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
