This single row cylindrical roller bearing is built with two ribs on the outer ring and one rib on the inner ring, giving it a semi-locating function within a bearing arrangement. Bore diameter is 70.0 mm, outside diameter 125.0 mm, width 31.0 mm, and net mass is 1.7 kg. The limiting speed reaches 10100 1/min, with a reference speed of 3850 1/min. The bearing uses an MPAX cage and features the E design for increased load rating, with radial internal clearance in group C3. The rib configuration allows the inner and outer rings to be displaced axially relative to each other, which supports compensation of thermal expansion and shaft movement in one direction while still providing axial guidance in the other. The C3 clearance accommodates temperature rise and interference fit effects during operation, making the bearing suitable for applications where a defined operating clearance must be maintained under load. The MPAX cage design supports stable roller guidance at the given speed range.
