Thrust radial ball bearing Thrust radial ball bearing can accept heavier two-way axial load and a small amount of radial load. It has good axial rigidity and is suitable for higher speed. It is mainly used for lathes, boring machines, radial drilling machines and other machine tools. Spindle.
Thrust ball bearings The contact angle of thrust ball bearings is 90", and the structure is separable, which can only accept axial load. Thrust ball bearings with spherical races are self-aligning, which can eliminate the influence of equipment errors. Steel balls due to centrifugal force Squeezed to the outside of the raceway, it is easy to scratch, so it is not suitable for high-speed operation. This type of bearing is mainly used for machine tool spindles, vertical lathe rotating tables, and automobile steering motions.
Miniature ball bearings whose inner diameter is less than 10mm or whose outer diameter is less than 26mm are called miniature bearings. Miniature ball bearings are mainly used for the appearance of various instruments, miniature motors, gyroscopes, automatic control organizations and medical devices.
Linear motion ball bearings Linear motion ball bearings consist of an outer ring, a cage (also known as a steel ball circulation frame) and 3 to 5 rows of steel balls. The conflict factor is much lower than that of sliding bearings, generally 0.001~0.003. This type of bearing has small radial clearance and high linear motion accuracy. It is mainly used for reciprocating organization of CNC machine tools, automatic appearance recording equipment, automatic tracking organization and stamping dies Guide post and so on.
The rollers of tapered roller bearings are in line contact or modified line contact with raceways. They can accept heavier combined radial and axial loads, as well as pure axial loads. They are mainly used for the front and rear wheels of automobiles. , Machine tools, rolling stock, rolling mills, construction machinery, lifting machinery, printing machinery and various deceleration equipment, etc. 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.
