EE161394/161901D 482.6 mm 354.013 mm Frequently Asked Questions about EE161394/161901D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the EE161394/161901D Double Row Tapered Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE161394/161901D with a precision bore diameter (d) of 354.013 mm, an outside diameter (D) of 482.6 mm, and a nominal ring width (B) of 133.35 mm. This configuration yields an effective cross-sectional wall thickness of 64.3 mm and an envelope ratio (D/d) of 1.36, delivering compact rigidity for OEM machinery housings.
Each EE161394/161901D 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 (354.013 mm bore side) ensures perfect planar contact without edge binding.
The CHG Bearing EE161394/161901D is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
