Cage and Holes：

The cage (or isolation block) adopts the full ball structure only when the load is large. The full ball four-point contact ball bearing has a large load-bearing capacity, but the friction resistance is large, and friction can easily cause scratches on the surface of the steel ball.

According to installation needs, the mounting holes can be designed as straight holes, counterbore holes, threaded blind holes, threaded through holes, etc.

MTO-145T is Ball slewing ring bearing small slewing bearing with none teeth.

It composed of two seat rings, compact in structure and light in weight. The steel ball is in contact with the

arc raceway at four points and can bear axial force, radial force and overturning moment at the same time.

The slewing bearing be produced as your demands,

1 Offer the size for us, our technicist will design the bearing

2 Offer the type for us, If that is standard, we can produce directly

3 Offer the drawing for us, we can produce as the same as the drawing.

MTO-145T Advantages:

1. Excellent rotation accuracy

The internal structure of the crossed roller bearing adopts the rollers arranged in a 90° crosswise arrangement.Spacers or spacers are installed between the rollers to prevent the rollers from observing each other when they are inclined.

In addition, there will be no contact or locking phenomenon on one side of the roller; at the same time, because the inner and outer rings are divided structures, the gap can be adjusted, even if preload is applied, high-precision rotation can be obtained.

2. Simplified operation and installation

The outer ring or inner ring, which is divided into two parts, is fixed together after the rollers and cages are installed, so the operation during installation is very simple.

3. Withstand large axial and radial loads

Because the rollers are arranged perpendicular to each other by spacers on the 90° V-groove rolling surface.

4. Significantly save installation space

The size of the inner and outer rings of the crossed roller bearing is miniaturized to a minimum, especially the ultra-thin structure is close to the limit of small size, and has high rigidity, so it is most suitable for the joints or rotating parts of industrial robots, and the rotation of machining centers.

Workbenches, manipulator rotating parts, precision rotating tables, medical instruments, measuring instruments, IC manufacturing equipment, etc. are widely used.

5. High speed capability
6. Reduce shaft length and processing costs, thermal expansion causes limited changes in geometric dimensions
7. Adopt nylon separator, low moment of inertia, low starting torque, easy to control angle indexing
8. Optimize pre-tightening force, high rigidity, and high precision of guiding roller operation
