Frequently Asked Questions about NN3196 Double Row Cylindrical Roller Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

Each NN3196 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (480 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies NN3196 with a precision bore diameter (d) of 480 mm, an outside diameter (D) of 790 mm, and a nominal ring width (B) of 248 mm. This configuration yields an effective cross-sectional wall thickness of 155.0 mm and an envelope ratio (D/d) of 1.65, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies NN3196 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.
To extend the trouble-free lifespan of CHG Bearing NN3196, 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.
