Heavy duty rod ends technical performance
Apr 13, 2018

Because the structural form and working mechanism of heavy-duty rod end are completely different from ordinary bearings, the heavy-duty rod end also has its own technical characteristics and maintenance requirements. The first to see is the working temperature of the heavy end of the rod, which is mainly determined by the mating material between the sliding surfaces of the bearing, especially the sliding surface of the plastic material of the self-lubricated rod end, which will have a decreasing bearing capacity at high temperatures.

 

If the material of the sliding face of the heavy duty rod ends are paired with steel/steel, the permissible operating temperature depends on the permissible operating temperature of the lubricant. However, for all lubricated and self-lubricated rod ends, they can be used within the temperature range of -30°C to +80°C and maintain the correct bearing capacity.

 

Followed by the heavy duty rod ends of the tilt, far more than the general adjustable ball bearing is much larger, it is suitable for the congruent requirements of the support site is not used. Not only that, the angle of the heavy end of the rod varies with the size, type, type of seal, and the form of the bearing. Generally, the inclination angle of the radial bearing ranges from 3° to 15°, and the inclination angle of the angular contact bearing ranges from 2° to 3°. Thrust bearings range from 6° to 9°.

 

At the same time, there is also the fitting of heavy-duty rod ends. In any case, the choices it uses must not cause uneven deformation of the ferrules. The selection of the mating properties and grades must be based on the bearing type, bearing type and load size and other working conditions. To decide.

 

In addition to heavy duty rod ends loading and unloading, the basic requirement is that the forces exerted by assembly and disassembly cannot be transmitted directly through the spherical sliding surface. In addition, auxiliary loading and unloading tools, such as sleeves, detachers, etc., should be used to directly and uniformly apply the loading and unloading forces applied by the outside to the mating ferrules, or to carry out loadless loading and unloading with auxiliary methods such as heating.
