Cylindrical roller bearings are precision mechanical components that withstand radial loads in a linear contact manner, characterized by high load-bearing capacity and high-speed adaptability
Composed of inner and outer rings, cylindrical rollers, and a cage, it adopts a detachable design for easy installation
2. According to the edge configuration, it can be divided into single row (such as NU, NJ, NUP) and double row (such as NNU, NN) structures. Among them, NU/N type allows axial displacement as the free end bearing, while NJ/NF type can be positioned unidirectionally
Special Design
DF type: Roller convexity modification eliminates edge stress, inclined edge improves axial load capacity
Fully loaded rollers: without cage design (such as NJ... V) suitable for extreme radial loads
Enhanced (E-type): Increasing the size of the rollers to enhance the load-bearing capacity, but not interchangeable with the regular type
