Single-row cylindrical roller bearing with a bore of 40.0 mm, outside diameter of 80.0 mm, and width of 23.0 mm, weighing 0.486 kg. The outer ring has two ribs and the inner ring has one rib, giving the NJ design its semi-locating function that allows axial displacement of the non-ribbed side while still transmitting radial load. The polyamide TVP2 cage guides the rollers, and the E design increases roller size and load rating compared to standard versions. Limiting speed is 12500 1/min, with a reference speed of 6300 1/min. Radial internal clearance corresponds to CN (Group N), suitable for standard fit and operating conditions without special preload requirements. As a semi-locating bearing, it accommodates axial shaft expansion on one side while supporting radial loads on the free side, making it suitable for shaft arrangements where controlled axial movement is required at one bearing position. The open design requires external sealing and separate lubrication, compatible with grease or oil depending on the housing arrangement.
