Self-Lubricating Bearing Nu2309e Nj2309e Nup2309e Cylindrical Roller Bearing for Conveyor Belt

Product Description

Product Description

Cylindrical rollers and raceways are in line contact bearings. It has a large load capacity and mainly bears radial loads. The friction between the rolling elements and the flange of the ring is small, making it suitable for high-speed rotation. According to whether the rings have flanges or not, they can be classified into single-row cylindrical roller bearings such as NU, NJ, NUP, N, and NF, as well as double-row cylindrical roller bearings such as NNU and NN. This bearing has a structure where the inner ring and the outer ring can be separated.

Cylindrical roller bearings with no flanges on either the inner or outer ring can have their inner and outer rings move relatively in the axial direction, so they can be used as free-end bearings. Cylindrical roller bearings with double flanges on one side of the inner and outer rings and a single flange on the other side of the ring can withstand a certain degree of axial load in one direction. Generally, steel plate pressed cages or solid cages made of copper alloy by turning are used. However, some also use polyamide forming cages.

Characteristics
1.The rollers and raceways are in line contact or modified line contact, with a large radial load-bearing capacity, making them suitable for withstanding heavy loads and impact loads.
2. It has a low coefficient of friction, is suitable for high speed, and its limiting speed is close to that of deep groove ball bearings.
3. N-type and NU-type can move axially, which can adapt to the changes in the relative position between the shaft and the housing 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 skew of the outer ring's axis must be strictly controlled to avoid contact stress concentration.
5. The inner or outer ring can be separated, which is convenient for installation and disassembly.
