This single row cylindrical roller bearing carries two ribs on the outer ring and one rib plus a loose rib washer on the inner ring, giving it a locating function within the shaft assembly. Bore is 40.0 mm, outside diameter 80.0 mm, width 18.0 mm, and net mass is 0.384 kg. The E design provides increased roller complement and load-carrying capacity within this envelope. Limiting speed is rated at 12500.0 1/min, with a reference speed of 7500.0 1/min. The polymer TVP2 cage separates the rollers and supports running at the stated speed values with reduced friction. Radial internal clearance C3 accommodates greater operating clearance than standard, suiting applications with elevated temperature rise or interference fits that reduce running clearance. As a locating bearing, the rib arrangement fixes the shaft axially in one direction, while the separable inner and outer rings simplify mounting and dismounting during assembly work.
