Advantages and unique properties of the spherical rod ends

- Jul 15, 2019-

Spherical rod ends are widely used for lower speed oscillating motions, tilting motions and rotary motions. Spherical plain bearings and rod end joint bearings are available in a variety of designs and have different combinations of sliding contact surfaces. Each design and combination has unique properties. To make it particularly suitable for certain applications.


The spherical rod end is widely used, including: spherical rod end joint steel ball welding, bearing metal rod and round steel ball welding, spherical joint bearing welding, end rod spherical joint spot welding, cross roller collar, needle cam Guides, roller guides, plain bearing welding, etc.


The spherical rod end is a spherical plain bearing, and the basic type is composed of inner and outer rings having a spherical sliding spherical contact surface. The joint bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand a large load. Depending on their type and construction, it is possible to withstand radial loads, axial loads or combined loads of radial and axial forces. Since the outer surface of the inner ring is provided with a composite material, the bearing can be self-lubricated during operation. Generally used for low-speed oscillating motion, it can also be tilted in a certain range of angles. When the support shaft and the shaft housing hole are different, they can still work normally.


Advantages of the spherical rod end


Spherical sliding contact area is large, the angle of inclination is large, it has large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubricating and non-lubricating dirt pollution, even if the installation is misplaced. Also works fine.


Easy maintenance and reliable quality. The use of rolling bearings can eliminate a series of complicated and technically demanding maintenance processes such as smelting, casting and scraping of babbitt alloy materials, as well as oil supply and water supply cooling systems, so the maintenance amount is greatly reduced. Moreover, since the rolling bearing is manufactured by a professional manufacturer, the quality is often guaranteed. It also brings convenience to the manufacturer of the ball mill.
