HyjgBearing's spherical plain bearings or bushings are steel-to-steel bearings consisting of a spherically ground inner ring housed in a matching outer ring without any rolling elements. While all plain bearings are precision ground and made from integrally hardened steel, custom orders are available, including special materials, clearances, surface finishes or configurations to suit unique applications.
Rings made from hardened steel help to provide consistent, reliable performance.
Phosphate-treated rings coated with molybdenum disulphide (MoS2) to minimise friction on contact surfaces
Simplified housing and shaft design reduces installation time.
A-frames, tipping cylinders, front and rear struts and steering cylinders for mining trucks
Equaliser track bars, lifting and tilting cylinders, push shovels, trunnion balls and loosening shovels for bulldozers
Articulated upper and lower steering cylinders and boom and bucket cylinders for wheel loaders
Bucket bar and bucket cylinders for hydraulic excavators
Other applications for space shuttles, heavy movable structures and miscellaneous vehicles
Spherical plain bearings (also known as "spherical plain bearings", "spherical ball bearings" and "ball bushings") have an inner ring with a convex outer ring and a correspondingly spherical but They are designed in such a way that they are particularly suitable for use in the production of bearings with a convex outer ring. Their design makes them particularly suitable for bearing arrangements where the alignment movement between shaft and housing must be adapted, or where oscillating or repeated tilting movements at relatively slow sliding speeds must be permitted.
Spherical plain bearings (also called "spherical plain bearings", "spherical ball bearings" and "ball bushings") have an inner ring with a convex outer ring and an outer ring with a corresponding spherical surface but a concave inner ring. The inner ring is concave. Their design makes them particularly suitable for bearing arrangements where the alignment movement between shaft and housing must be adapted, or where oscillating or repeated tilting movements at relatively slow sliding speeds must be permitted.
Steel-to-steel spherical bushings handle alternating and shock loads in a variety of industrial machinery and construction equipment.
High-carbon chromium bearing steel for inner and outer rings.
Phosphate-treated sliding surfaces are dry-coated with molybdenum disulfide (MoS2) to provide excellent wear resistance, high load capacity and low-torque operation.
Optional polyurethane seals prevent grease leakage and dirt penetration.
These bushings are ideal for applications with fixed directional loads or applications where lubrication is not possible or desired, such as food processing machinery, construction equipment, and applications where oil is not desired or difficult to lubricate.
The durable outer ring has a PTFE lining that is reinforced with a copper alloy mesh on the sliding surface.
The spherical inner ring has a hard chrome plated sliding surface.
Effective wear resistance and low creep deformation ensure long maintenance-free operation.
Optional synthetic resin seals prevent dust penetration.
The spherical plain thrust bearing has a convex sphere on the bearing washer and a concave sphere on the bearing race correspondingly. Though being applicable to axial load, such bearing is also able to withhold joint load from both axial and radial directions. However, the radial load for joint load shall be less than 50% of the axial load. If the radial load is larger, it is recommended to collectively used the thrust bearing together with the radial bearing of GE series. With separable design, the bearing washer and bearing race
Special design
When being operated under special conditions, the spherical thrust roller bearing may be used and which requires be made by steel/steel or steel/PTFE (maintenance-free) compound materials and integrated with sliding contact surface. This kind of bearing can be supplied as needed.
If it is required to operate the bearing without lubricating, the bearing integrating with maintenance-free steel/PTFE compound sliding contact surface shall be adopted (Figure 2). Such combination can withhold heavy load, especially directed heavy load.
