This single row cylindrical roller bearing carries radial loads and functions as a locating bearing, with two ribs on the outer ring and one rib plus a loose rib washer on the inner ring, type NUP. Bore diameter is 70.0 mm, outside diameter 150.0 mm, width 35.0 mm, and mass is 3.18 kg. The E design provides an increased load rating over standard internal geometry. Cage type M1 (machined brass) guides the rollers, limiting speed is rated at 8200 1/min and reference speed at 4500 1/min. Radial internal clearance C3 (Group 3) accommodates thermal expansion and shaft fit interference beyond normal clearance, suiting applications where the shaft runs at elevated temperature or requires a tighter fit. The locating design fixes the shaft axially in both directions through the rib configuration, while the separable inner and outer ring construction simplifies mounting and dismounting. No sealing is specified, so lubrication and contamination protection must be provided externally by the housing arrangement.
