Advantages of precision ball bearings:
Precision ball bearings have very small clearances and meet the most stringent requirements in terms of operating characteristics, load capacity, and durability. The environment has almost no effect on ball bearings. This makes ball shaft bearings particularly suitable for industrial casters that must meet strict technical conditions. At the same time it is also used for heavy-duty casters.
Wheel bearings with heat-resistant precision ball bearings can be used at extremely low temperatures and extremely high temperatures. Under these thermal conditions, the load capacity will be slightly reduced.
Radial deep groove ball bearings require almost no maintenance. Even under continuous operation, wear is low, and there is no need to replace bearings. Under applicable strict hygiene regulations, such as in the medical or food industries, wheels should be equipped with sealed ball bearings.
Generally, bearings with an inner diameter of less than 10mm or an outer diameter of less than 28mm are called miniature bearings. Mainly used for instrumentation and medical equipment.
Its characteristics are:
1. Miniature bearings used in synchronous motors and servo motors are mainly centripetal ball bearings with dust caps, which often make supplementary requirements for friction torque, which are easy to start and run smoothly.
2. In order to meet the requirements of high-precision and high-speed operation of gyro motors, high-precision centripetal thrust ball bearings or centripetal thrust ball bearings with thrust ribs are often used. The latter can simplify installation and reduce errors. There is also a direct design of the outer ring into the shape of the motor end cover, which is called an end cover bearing.
3. The gyroscope frame support requires a small frictional moment to reduce the drift rate of navigation. In addition to the selection of ordinary radial ball bearings, a multi-standard structure has been developed. The radial ball bearings with straight raceways on the outer ring have a much smaller frictional torque, but they cannot be positioned axially. The three-ring bearing, the middle ring is connected by gears for operation, the steel ball rolls along the raceway, and the movement friction torque is used to replace the starting friction torque, and the navigation accuracy is significantly improved.
