1.Roller and raceway are in line contact or trimming line contact, the radial bearing capacity is large, suitable for bearing heavy load and impact load.
2.Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.
3. N type and NU type can be moved in axial direction, which can adapt to the change of relative position of shaft and shell caused by thermal expansion or installation error, and can be used as free end support.
4.The machining requirement of shaft or pedestal hole is high, and the relative deflection
5.The inner ring or outer ring can be separated for easy installation and disassembly.of the outer ring axis should be strictly controlled after the bearing is installed, so as to avoid the contact stress
