This single-row cylindrical roller bearing carries a bore of 65.0 mm, outside diameter of 140.0 mm, and width of 33.0 mm, with a net mass of 2.34 kg. The outer ring has two ribs and the inner ring one rib with an internal rib washer, giving the NUP configuration a locating function that fixes axial position in one direction while allowing free axial displacement in the other. The E design reflects an optimized internal geometry for increased load carrying capacity, and the polyamide cage (TVP2) reduces weight and friction versus a machined cage. With CN (Group N) radial internal clearance, this bearing suits applications requiring a locating support with standard running clearance. Limiting speed is 6800 1/min and reference speed is 4800 1/min, which sets the practical upper range for continuous operation. As an open bearing without integrated seals, it requires external sealing and relubrication provisions; the separable inner ring simplifies mounting and dismounting in shaft assemblies where axial fixation at one bearing position is needed.
