Cylindrical roller bearing
Cylindrical roller bearings have high load-bearing capacity and are suitable for fields such as construction machinery and elevators.
According to the presence or absence of retaining edges on the ring, there are types of single row bearings such as NU, NJ, NUP, N, NF, as well as double row bearings such as NNU and NN.
This bearing is a separable structure with inner and outer rings
