Features of single-row cylindrical roller bearings
1. The roller and raceway are in line contact or modified line contact, with large radial load capacity, suitable for bearing heavy loads and impact loads. 2. The friction coefficient is small, suitable for high speed, and the limit speed is close to that of deep groove ball bearings. 3. N-type and NU-type can move axially, can adapt to the changes in the relative position of the shaft and the housing caused by thermal expansion or installation errors, and can be used as free end supports. 4. The processing requirements for the shaft or seat hole are high. The relative deflection of the outer ring axis after the bearing is installed must be strictly controlled to avoid contact stress concentration. 5. The inner ring or outer ring can be separated for easy installation and disassembly.
Main uses: large and medium-sized motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, reduction gearboxes, rolling mills, vibrating screens, and lifting and transportation machinery.
