The features and advantages of cylindrical roller bearing

Cylindrical roller bearings with no ribs on the inner ring or outer ring, the inner ring and outer ring can move relative to the axial direction, so they can be used as free end bearings. A cylindrical roller bearing with double ribs on one side of the inner ring and outer ring, and a single rib on the other side of the ring, which can withstand a certain degree of axial load in one direction. Steel stamping cages are generally used, or copper alloy car-made solid cages. But there are also some polyamide shaped cages.

The features of cylindrical roller bearing:

  1. The rollers and the raceway are in line contact or trimmed line contact, with large radial bearing capacity, 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, can adapt to changes in the relative position of the shaft and the shell caused by thermal expansion or installation errors, and can be used as free end supports.
  4. The processing requirements for the shaft or seat hole are relatively high. After the bearing is installed, the relative deviation of the axis of the outer ring must be strictly controlled to avoid contact stress concentration.
  5. The inner or outer ring can be separated for easy installation and removal

The advantages of cylindrical roller bearing:

1. The cylindrical rollers are in line contact with the raceway, and the radial load capacity is large. It is suitable for bearing heavy loads and shock loads, and is also suitable for high-speed rotation.

2.Cylindrical roller bearing raceways and rolling elements are geometrically shaped. After the improved design, it has a higher bearing capacity. The new structural design of the rib and the end face of the roller not only improves the axial bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the end face of the roller and the rib, and improves the bearing capacity. Bearing performance.
