NU 2317 ECP

NU 2317 ECP Cylindrical Roller Bearing – Technical Specifications & Load Performance Engineered for heavy industrial applications requiring high radial stiffness, the NU 2317 ECP features an optimized internal geometry (E-design) that maximizes load distribution across the rollers. With dimensions of 85x180x60 mm, this single row bearing delivers a basic dynamic load rating of 455 kN and a static load rating of 490 kN, making it exceptionally durable under heavy static or shock loads. The "CP" suffix indicates the inclusion of a glass fiber reinforced polyamide 66 cage, which reduces friction and operating temperatures compared to steel cages, allowing for higher reference speeds up to 4000 r/min while maintaining structural integrity in challenging environments.

Installation, Maintenance, and Axial Displacement The NU design configuration-characterized by two integral flanges on the outer ring and a flangeless inner ring-allows the shaft to accommodate axial displacement in both directions relative to the housing, essential for managing thermal expansion in equipment like large electric motors and gearboxes. Its separable components significantly simplify maintenance routines; the inner ring can be mounted or dismounted independently from the outer ring assembly, facilitating interference fits without damaging the rolling elements. This modularity reduces downtime during replacement and ensures precise alignment in demanding machinery such as pumps, compressors, and traction motors.
