滚珠轴承cylinderical

Cylindrical roller in line contact with the bearing raceway. Load capacity, mainly bear radial load. Rolling ring ribs with small friction, suitable for high-speed rotation. Whether the ribs under the ferrule can be divided into NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN and other double row bearings. The bearing is the inner ring, outer ring detachable structure. No inner or outer ribs of the cylindrical roller bearings, the inner and outer rings can be relative to the axial movement, so you can use as a free end of the bearing. In the inner and outer rings of a double-side ribs, the other side of the ring has a single rib of cylindrical roller bearings, can withstand a certain degree of axial load in one direction. General use of steel stamping cage, or copper alloy cage car system. But there are also part of the use of polyamide forming the cage.
