Equal-section thin-walled bearings and crossed cylindrical roller bearings are the two main categories of industrial robots. In addition, there are harmonic reducer bearings, linear bearings, joint bearings and so on.

The bearing of the industrial robot is one of its key components, and is most suitable for the joint or rotating part of the industrial robot, the rotary table of the machining center, the rotating part of the robot, the precision rotary table, the medical instrument, the measuring instrument, and the IC manufacturing device. And so on.

Industrial robot bearing features: can withstand axial, radial, overturning and other comprehensive load; thin-walled bearings; high-slewing positioning accuracy. Any bearing that meets this design requirement can be used in industrial robot arms, swivel joints, and chassis.

The internal structure of the crossed roller bearing is arranged at 90° perpendicular to each other by rollers. The spacers or spacers are arranged between the rollers, which can prevent the inclined rollers of the rollers from being mutually inspected and effectively prevent the rotational torque. Increase. In addition, the contact phenomenon or the locking phenomenon of the roller does not occur; at the same time, since the inner and outer rings are divided structures, the gap can be adjusted, and even if the preload is applied, a high-precision rotary motion can be obtained.

The equal-section thin-walled bearing is composed of seven open series and five sealed series. There are three types of open series: radial contact type C, angular contact type A and four point contact type X. Advantages of thin-walled equal-section bearings: Thin-walled bearings achieve extremely thin bearing sections, and also achieve miniaturization and weight reduction of products. The diversity of products extends the range of uses.

Thin-walled isometric bearings, also known as thin-walled ferrule bearings, are highly accurate, very quiet and have a high load carrying capacity. Thin-walled ferrule bearings can be deep groove ball bearings, four-point contact bearings, angular contact ball bearings, thin-walled and other cross-section bearings are mostly square. In these series, even with larger shaft diameters and bearing bores, the cross section remains the same. These bearings are therefore referred to as equal sections. It is this feature that distinguishes thin-walled ferrule bearings in the standard ISO series from conventional bearings. Therefore, a larger cross section can be selected and a more load bearing bearing can be used without having to change the shaft diameter. Thin-walled ferrule bearings can be designed to be extremely light and require very little space.
