Description of NN3022K Bearings Truck
Cylindrical Roller Bearings are a type of rolling bearing that uses cylindrical rollers as the main load-bearing element. These bearings are primarily designed to handle radial loads and offer high load capacity. The low friction between the roller and the cage makes them ideal for high-speed applications. They can be classified into single-row (NU, NJ, NUP, N, NF) and double-row (NNU, NN) bearings based on the presence of flanges on the rings.The inner and outer rings are separable, which simplifies installation and maintenance.
Cylindrical roller bearings provide the highest radial load capacity compared to other types of roller bearings.
