This cylindrical roller bearing carries the design NU209-E-XL-TVP2-C3, a single row non-locating bearing with two ribs on the outer ring and a smooth inner ring, allowing free axial displacement between the rings. Bore diameter is 45.0 mm, outside diameter 85.0 mm, width 19.0 mm, and net mass 0.42 kg. The polyamide cage is designated TVP2, radial internal clearance falls in group C3, and running accuracy corresponds to tolerance class P6. Limiting speed reaches 10200 1/min, with a reference speed of 7000 1/min. The non-locating design lets this bearing absorb axial shaft expansion, making it suitable as the floating bearing in a shaft arrangement while the increased C3 clearance compensates for thermal growth during operation. The E design provides higher radial load carrying capacity within the same envelope dimensions, and the P6 accuracy class supports applications requiring tighter running tolerances than standard P0. The TVP2 cage guides the rollers securely at the given speed range, and the open construction requires external sealing and separate lubrication to be provided in the housing.
