1. The rollers are in linear contact with the raceways, with large radial bearing capacity, and are suitable for bearing heavy and shock loads.

2. The friction coefficient is small, suitable for high speed, and the limiting speed is close to deep groove ball bearings.

3. Models N and NU can move axially, can adapt to the change of the relative position of the shaft and the housing due to thermal expansion or installation errors, and can be used as free end support. The inner or outer ring can be separated for easy installation and removal.

4. The processing requirements of the shaft and seat hole are relatively high. The relative deflection of the inner and outer ring axes after the bearing is installed must be strictly controlled to avoid causing contact stress concentration.

5.Double-row cylindrical roller bearings with a 1:12 taper inside bore. The radial clearance can be adjusted and the radial rigidity is high, which is suitable for the machine tool spindle.
