This single row cylindrical roller bearing carries two ribs on the outer ring and one rib on the inner ring, configuring it as a semi-locating bearing that permits axial displacement in one direction while providing radial guidance. Bore diameter is 40.0 mm, outside diameter 90.0 mm, width 33.0 mm, and net mass 1.057 kg. The E design denotes the reinforced internal geometry typical of this series, and the bearing is fitted with an M1 cage. Limiting speed reaches 14200 1/min, with a reference speed of 5800 1/min. The C3 radial internal clearance provides increased internal play, compensating for thermal expansion during operation and shaft fit tolerances. The semi-locating configuration allows the inner ring to move axially relative to the outer ring, accommodating thermal growth along the shaft while the ribs maintain radial load support. The M1 cage guides the rollers under the specified speed range, and the E design supports the roller complement suited to the stated load and speed parameters.
