Spherical plain bearings (plugged graphite), or bushings, are metal-on-metal bearings consisting of a spherically ground inner ring housed in a mating outer ring without any rolling elements.

Spherical plain bearings have a self-aligning function and are suitable for applications where the rotating shaft has a deflection angle. The sliding bearings are self-aligning bearing unit systems made entirely of metal-graphite self-lubricating bearings. They include base bearings, rod-end bearings, and spherical bearings, and the product range is constantly being expanded.

Self-Lubricating Spherical Bearings

Suspension Bridges maintenance-free bearings. The spherical plain bearings with self-lubricating material technology will accommodate the small but important movements that occur between the bridge and its supporting cables.

“Wind pressure, loads and vibrations from traffic flow and temperature variations are all causes of roadway movement on suspension bridges,” said the low-maintenance, but very effective solution Suspension Bridges maintenance-free bearing oscillating bearing; spherical plain bearing solution.

Conventional roller bearings are not suitable for bridges under constant heavy loads for long periods of tiny movements and the possibility of surface failures. Our company’s oscillating bearing; spherical plain bearing solves this problem by providing a larger load bearing surface, providing sufficient durability for the life of the bridge without the need for repair or replacement.

The design of each oscillating bearing; spherical plain bearing mount ensures that even if the sliding layer is damaged by exposure to loads in excess of the design value, the structure of the joint is protected and the function of the sliding bearing is reduced.

These challenging requirements developed bearing solutions, and engineers used a combination of materials from the standard, well-proven product line of self-lubricating oilless bearings. The connecting balls are made of metallic materials and are pressed into the manufactured plain bearings. Low-friction plain bearings include a backing made of steel, stainless steel, or bronze and a surface layer for self-lubricating bearings. The surface layer is a bronze material manufactured using powder metallurgy technology – it is not porous and oil-impregnated, but highly compressed and coated with a solid lubricant material, such as graphite or PTFE.

The bearing housing forms a two-part spherical ring to provide longer maintenance-free service life, high static and dynamic load capacity, and low friction characteristics produced by a uniform layer of solid lubricant.

The design is completed by the use of a thrust self-lubricating bearing, also made from, which absorbs axial forces. This bearing is ideal for dry running at slow sliding speeds, has a very high resistance and is well suited to extreme temperatures and corrosion.

This is not the first time that plain bearings have provided a reliable, low-maintenance solution for bridge construction projects. Many bridges around the world have benefited from this self-lubricating bearing technology for bridge design applications.

A leading global supplier of plain bearings and self-lubricating bearings, the company provides products and services to vehicle and equipment manufacturers and service personnel in the automotive, light, medium, and heavy commercial, marine, rail, power generation, and industrial markets worldwide.

 

Radial Spherical Plain Bearings
A spherical plain bearing (plugged graphite), or bushing, is a metal-to-metal bearing consisting of a spherically ground inner ring mounted in a mating outer ring without any rolling elements. While all plain bearings are precision ground and made of hardened steel, they can be customized to include special materials, clearances, surface finishes or configurations to suit unique applications.

Size Range. Available in bore diameters from 12.7 mm to 600 mm (0.500 in. to 23.622 in.).

Design Attributes
Rings manufactured from hardened steel help provide consistent, reliable performance.
Phosphate-treated steel collars coated with molybdenum disulfide (MoS2) minimize friction on contact surfaces.
Simplified housing and shaft design reduce installation time.
Applications
A-frames, tipping cylinders, front and rear struts, and steering cylinders for mining trucks
Equalizing track bars, lift and tilt cylinders, dozer blades, trunnion balls, and trencher blades for bulldozers
Articulated upper and lower steering cylinders and movable arm and bucket cylinders for wheel loaders
Rod and bucket cylinders for hydraulic excavators
Other applications for space shuttles, heavy movable structures, and various vehicles

self-lubricating radial spherical plain bearings

The outer ring of this bearing is a steel sleeve, the inner layer is a solid mosaic bearing. It is on the base of high-strength brass. A high-performance solid lubricant product inlaid with graphite or mos2 solid lubricants.It breaks through the limitations of general bearings relying on oil film lubrication. During use, the solid lubricant graphite is rubbed against the shaft by frictional heat, Excellent conditions for the formation of oil and powder,It can replace traditional flanged linear motion bearings, and linear sliding bearings, and make the solid lubrication characteristics eternal.

Oilless bearing embedded with solid lubricant, has a  spherical shape.

A spherical bearing is a  bearing in which the journal portion of the bearing
