What force can the biaxial short cylindrical roller bearings bear?
Mainly used to bear radial load, but also can bear certain axial load, when the bearing radial clearance increased, with angular contact ball bearings performance, can withstand larger axial load. The friction coefficient of this kind of bearing is small, the limit speed is high, and the range and form of the bearing are varied. Solid and durable, versatility and low noise operation. It can operate at high speed and easy to install. Single row deep groove ball bearings are hermetically sealed and can be designed without lubrication or maintenance. Single row with ball notch and double row ball bearings, suitable for heavy load conditions. Thrust ball bearings: rolling bodies are thrust ball bearings. Roller bearings: rolling bodies are roller bearings. Cylindrical roller bearings: rolling bodies are cylindrical roller radial roller bearings, is a separate type bearings, installation and disassembly is very convenient. Cylindrical roller bearings are divided into single row, double row and four column. Cylindrical roller bearings can be divided into single row, double row and multi row cylindrical roller bearings according to the number of rolling elements in the bearing. Among them, a single row cylindrical roller bearing with cage is used more. In addition, there are single column or double row full installed roller and other structures of cylindrical roller bearings. Single row cylindrical roller bearings are divided into N, NU, NJ, NF and NUP, depending on the ring edge of the ring.
Types of bearings angular contact bearings: ball and ring nominal contact angle greater than 0 degrees, while less than 90 degrees of rolling bearings. Can bear radial load and axial load at the same time. Able to work at a higher speed. The greater the contact angle is, the higher axial bearing capacity is. High precision and high speed bearings usually take 15 degrees of contact angle. The contact angle will increase when the axial force is applied. Single row angular contact ball bearings can only bear axial load in one direction, and will cause additional axial force when subjected to radial load. And only the axial displacement of the shaft or shell in one direction can be limited. In pairs, the outer ring of a pair of bearings is opposite, i.e., the wide end face to the wide end face and the narrow end facing the narrow end face. In this way, additional axial forces can be avoided and the shaft or housing can be confined in the axial clearance within two directions. Outer spherical bearing: radial roller bearing with wide spherical ring with outer sphere and locking parts. Mainly for easy shell use. Linear motion bearing: two roller, rolling in the direction of relatively linear motion of rolling bearings. Ball bearings: rolling bodies are balls of rolling bearings. Deep groove ball bearings: ball bearing continuous groove of each ring has a cross section of the ball about three weeks of the raceway, suitable for precision instruments, low noise motor, automobile, motorcycle and general machinery and other machinery industry, is used most widely as a kind of bearing. Simple structure, easy to use and maintain.
