Product Description
The main difference between cylindrical roller bearings and other bearing styles is in the name - they use cylinders as the rolling elements as opposed to the balls you'd find in ball bearings. The cylinders are slightly greater in length than diameter. Compared to ball bearings, cylindrical rollers have a greater radial load capacity. The cylindrical roller design also allows these parts to accept relatively faster speeds than other styles of roller bearings.
Types:1. Single row cylindrical roller bearings;2. High-capacity cylindrical roller bearings;
3. Double row cylindrical roller bearings;
4. Four-row cylindrical roller bearings;
5. Single row full complement cylindrical roller bearings;
6. Double row full complement cylindrical roller bearings;
7. Cooper split cylindrical roller bearings,etc
Features:1. The roller and the raceway are in line contact or trimmed line contact, and the radial bearing capacity is large, which is suitable for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and the limit speed is close to that of deep groove ball bearings.
3. N type and NU type can move axially, which can adapt to the change of the relative position of the shaft and the shell caused by thermal expansion or installation error, and can be used as free end support.
4. The processing requirements for the shaft or seat hole are high, and the relative deflection of the outer ring axis after the bearing is installed should be strictly controlled to avoid contact stress concentration.
5. The inner ring or outer ring can be separated for easy installation and removal
