Cylindrical roller bearings have a large load-bearing capacity and mainly bear radial loads. The friction between the rolling element and the retaining edge of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. The bearing has a separable structure with an inner ring and outer ring. Cylindrical roller bearings are very suitable for various precision machinery and mining mill machinery.
Single-row cylindrical roller bearings: Single-row cylindrical roller bearings are separable bearings, which are easy to install and disassemble. Both rings can be tightly fitted, and the contact line between the roller and the raceway can be modified to reduce stress concentration. Double-row cylindrical roller bearings: Double-row cylindrical roller bearings are floating bearings, and their separability makes installation and disassembly easy. Both ferrules can be tightly fitted. The double-row cylindrical roller bearing almost does not allow an inclination angle.
There are many types of double row cylindrical roller bearings, which are mainly used in machine tools, rolling stands, plastic drums, grinders, and large gearboxes.
TEDIN just finished a batch of large-size double row cylindrical roller bearings NN3072K/P5, they are ready for delivery to our German customer.
