YOGIE cross roller bearings, because the internal ring or external ring is divided, after being loaded into the roller and spacer, it is fixed together with the cross roller shaft ring to prevent them from separating from each other, so it is easy to operate when installing the cross roller shaft ring.
Because the rollers are interlocked, only 1 set of interlocked rollers can bear the load in all directions.
At the same time, because the cross roller bearing inner ring or outer ring is a two-part structure, bearing clearance can be adjusted, even if the preload is applied, also can obtain high precision rotation movement.
1. YOGIE cross roller bearing has excellent rotation accuracy
The internal structure of crossed roller bearings by roller are arranged 90 ° vertically cross each other, with intervals between roller device or isolation block, can prevent tilt to friction between the roller of roller.
In addition, there will be no roller side contact or lock phenomenon;
At the same time, because the inner and outer rings are segmented structure, the clearance can be adjusted, even if the preloading is applied, the rotation motion can be obtained with high accuracy.
2. The operation and installation of YOGIE cross roller bearing are simplified
The outer ring or inner ring, which is divided into two parts, is fixed together after the rollers and retainers are loaded, so the installation operation is very simple.
3. Bear large axial and radial loads
Because of the roller in the 90 ° V groove rolling surface by interval retainer is vertically to each other.
4. YOGIE cross roller bearing significantly saves installation space
YOGIE cross roller bearing inner and outer ring size is minimal miniaturization, especially ultra-thin structure is close to the limit of small size, and high rigidity, so the most suitable for the joints of the industrial robot parts or rotating parts, machinery processing center of the rotary worktable, mechanical rotary department, precision rotary worktable, medical instruments, measuring instruments, such as IC manufacturing equipment widely used.
5. High rotational speed
6. Reduce shaft length and machining cost, and thermal expansion leads to limited changes in geometric dimensions
7. Nylon divider, low inertia, low starting torque, easy to control Angle division
8. Optimized preload, high stiffness and high running precision of the guide roller
9. Carburized steel provides excellent impact and surface wear resistance
Simple but well lubricated
