46215 115 mm 75 mm Frequently Asked Questions about 46215 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 46215 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
To extend the trouble-free lifespan of CHG Bearing 46215, 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46215 with a precision bore diameter (d) of 75 mm, an outside diameter (D) of 115 mm, and a nominal ring width (B) of 30 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 1.53, delivering compact rigidity for OEM machinery housings.
Model 46215 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 75 mm) and steep thermal gradients between inner and outer rings.
