Introduction

Cylindrical roller bearings are an important type of rolling bearing, mainly used to bear radial loads and can exhibit a low coefficient of friction during high-speed rotation.

Characteristics

Strong radial load - carrying capacity: The cylindrical rollers are in line contact with the raceway, enabling them to withstand large radial loads.

Low coefficient of friction: The friction between the rolling elements and the rib of the ring is small, making it suitable for high - speed rotation.

Diverse structures: According to the presence or absence of ribs on the rings, 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, NN. These different types of bearings are suitable for different application scenarios.

Application scenarios

Cylindrical roller bearings are widely used in fields such as medium - and large - sized electric motors, railway vehicles, etc. Due to their strong load - bearing capacity, low friction, and suitability for high - speed rotation, they perform outstandingly in these fields.
