What are the characteristics and uses of Bearing rollers

Both the ball Bearing and the Bearing roller belong to the Bearing roller. Simply put, the rolling body is a ball, that is, a steel ball. The other rolling element is a steel column. A kind of Bearing roller, the ball is installed in the middle of the inner steel ring and the outer steel ring, and can bear a large load. Also known as ball Bearing.

The ball Bearing mainly includes four basic elements: ball, inner ring, outer ring and cage, as shown in the figure. General industrial ball Bearing meet standards. The balls and rings are usually made of high chromium steel with a Rockwell C hardness of about 61-65. The hardness of the cage is lower than that of the steel ball and the ferrule, and the material is metal or non-metal. Bearing the rotational friction resistance of the roller is smaller than that of the journal Bearing, the temperature due to friction will be lower at the same speed.

The rolling body is a centripetal Bearing roller of the Bearing roller. Bearing rollers and raceways are line contact Bearing. Bearing capacity, mainly to bear radial load. The friction between the rolling body and the retaining ring edge is small, suitable for high-speed rotation. According to whether the ferrule has rib, there are NU, NJ, NUP, N, NF and other single-row Bearing and NNU, NN and NN double-row Bearing. The Bearing is a structure in which the inner ring and the outer ring can be separated. Cylindrical Bearing rollers with no ribs on the inner or outer ring. The inner and outer rings can move axially relative to each other, so they can be used as free-end Bearing. Cylindrical Bearing rollers with double ribs on one side of the inner ring and outer ring and single ribs on the other side of the outer ring can bear a certain degree of axial load in one direction. Generally, steel stamping cage or copper alloy turning cage is used. However, there is also a part of the use of polyamide molding cage.

What is the difference between a cylindrical Bearing roller and a Roller pin Bearing? Where can it be used? Today, I will give you a detailed introduction to the difference between a cylindrical Bearing roller and a Roller pin Bearing? What are the characteristics? Where can it be used? Cylindrical Bearing rollers are precision Bearing. The rib guide of precision sorting Roller collar is composed of cage, Roller and guide collar. It can be separated from another Bearing ferrule and belongs to the separable Bearing. This Bearing is more convenient to install and remove, especially when the inner and outer rings are required to have an interference fit with the shaft and the housing, it shows its advantages.

Such Bearing and raceways are line contact Bearing. Bearing capacity, mainly to bear radial load. Only single row Bearing with inner and outer ring ribs can bear small constant axial load or large intermittent axial load; compared with other Bearing with the same size, this type of Bearing has the characteristics of high load and low noise. It has the characteristics of high speed and high speed, and the friction between the rolling body and the ring rib is small, which is suitable for high-speed rotation. Very suitable for all kinds of precision machinery and mining machinery. However, the shafts, rolling elements and other related parts that cooperate with such Bearing need to be precisely machined.

According to whether the ferrule has ribs, it can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical Bearing rollers and NNU, NN and other double-row cylindrical Bearing rollers. A Bearing is a structure in which an inner ring and an outer ring can be combined.
