Ceramic Spark Plug Ignition Electrode
Their rollers and the outer wheels are arranged in a right angle intersecting intersecting. They can bear the load from all directions at the same time (such as axial, thrust or momentum hormones, etc.). Because of the linear contact between the roller and the track surface, the possibility of the axis to bear the load and the elastic deformation is very small. This type of bearing is widely used in industrial robots, working machines and medical facilities. It needs high rigidity, high speed and high speed to ensure precise occasions.
In cross roller bearings, cylindrical rollers are perpendicular to each other through spacer retainers on the top, so 1 cross roller bearings can bear all loads of radial load, axial load and torque load. Ring size is the minimum limit of miniaturization, especially very thin type is small size close to the limit, and has high rigidity, so the most suitable for use in industrial robot joint or rotating parts, machining center machine rotary table, hand rotating parts, precision rotary table, medical machine, metering device, IC manufacturing equipment etc.
1. Excellent rotation accuracy

Sillimatin 60 Type C 530, Alsint 99.7 Type C 799 and Pythagoras Type C 610, all complying with DIN VDE 0335.
The main applications are in the area of thermal processes. Protection tubes, insulators, radiant tubes, support tubes for electric heaters, beams, profiles, incineration aids and special fabrications.
The Impervious Materials are:
Alsint(Re-crystallised Alumina) is rated to 1700oC
Pythagoras(Aluminous Porcelain) is rated to 1400oC
The Porous Material is:
Sillimantin 60 and is rated at 1350oC
Sillimantin has better thermal shock resistance and is used mainly in furnace tubes, however can be used as an outer protection sheath if thermal shock is critical.

The inner structure of the Cross Roller Bearing is arranged in 90 degrees perpendicular to each other by the roller.
The roller is equipped with a spacer or isolation block between the rollers to prevent the rolling of the rollers from being examined each other. In addition, the phenomenon of roller contact or locking will not occur. At the same time, because the inner and outer ring is a segmented structure, the clearance can be adjusted, even if the preload is applied, high accuracy rotation motion can also be achieved.
2. Simplification of operation and installation
The outer ring or inner ring, which is divided into 2 parts, is fixed together after loading the roller and the holder, so the operation is very simple.
3. Bear large axial and radial load
The roller is arranged vertically through the spacer retainer on a 90 degree V groove rolling surface.
4. Greatly save the installation space
The size of the inner and outer ring cross Roller Bearing is miniature minimal, especially ultra-thin structure is small size close to the limit, and has high rigidity, so the most suitable for industrial robot joints or rotating parts, machining center of the rotary table, the robot rotating parts, precision rotary table, medical instrument IC, measuring equipment, manufacturing device widely used.
5. high speed ability
6. reducing shaft length and machining cost, thermal expansion leads to a limited change in geometric size.
7. the nylon separator is used, the moment of inertia is low, the starting torque is low, and the angle degree is easy to control.
8. optimization of pretightening force, large rigidity, high precision of guiding roller
9. carbon steel provides excellent impact resistance and surface abrasion resistance
10. simple but fully lubricated
