The friction factor is much lower than that of sliding bearings

Thrust ball bearing The contact angle of the thrust ball bearing is 90”, the structure is separable, and can only bear axial load. The friction factor is much lower than that of sliding bearings, generally 0. It has good axial rigidity and is suitable for higher speed. Double-row tapered roller bearings are mainly used for machine tool spindles and rolling stock, and four-row tapered roller bearings are used for roll support.

They are mainly used in automobiles. It is mainly used in the reciprocating mechanism of CNC machine tools, automatic instrument recording devices, automatic tracking mechanisms, and guide posts of stamping dies. Thrust radial ball bearing Thrust radial ball bearing can bear heavier two-way axial load and a small amount of radial load. Miniature ball bearings whose ier diameter is less than 10mm or whose outer diameter is less than 26mm are called miniature bearings.001 ~ 0.

Thrust ball bearing with spherical seat ring has self-aligning property, which can eliminate the influence of installation error. It is mainly used for lathes, boring machines, and radial drilling machines. This kind of bearing non-standard bearings is mainly used for machine tool spindle, vertical lathe rotating table, automobile steering motion, etc. 4. 2..ufeffUnderstand the types and uses of rolling bearings: 1. This type of bearing has small radial clearance and high linear motion accuracy. 5. The front and rear wheels, machine tools, rolling stock, rolling mills, construction machinery, hoisting machinery, printing machinery and various deceleration devices. Wait for the machine spindle.003.

Steel ball Because the centrifugal force squeezes to the outside of the raceway, it is easy to scratch, so it is not suitable for high-speed operation. Tapered roller bearings. Linear motion ball bearing Linear motion ball bearing is composed of outer ring, cage (also known as steel ball circulation frame) and 3~5 rows of steel balls. The rollers and raceways of tapered roller bearings are in line contact or modified line contact, which can bear heavier combined radial and axial loads, as well as pure axial loads. 3. Miniature ball bearings are mainly used in various instruments, micro motors, gyroscopes, automatic control mechanisms and medical equipment
