Spherical Plain Bearings - Wuxi Huihao Bearing Co., Ltd.

Spherical Plain Bearings

Spherical plain bearings are manufactured in a wide variety of materials and are designed to offer bearing solutions in almost any operating environment. 

Huihao Bearing offers a complete line of spherical bearings available in inch and metric. These High-Quality Spherical Plain Bearings are suitable for heavy-duty, off-highway vehicles, agricultural equipment, construction and mining and logging equipment, packaging and textile equipment, and robotics. 

The plain bearings come in standard industrial bore sizes from 0.5" to 12" inches, as well as metric sizes from as small as 4 to 300 mm.  

Spherical Plain Bearings Characteristics

Spherical Plain Bearings (also known as “Spherical Plane Bearings” "Spherical Ball Bushing Bearings" and “Ball Bushings”) have an inner ring with a sphere convex outside surface and an outer ring with a correspondingly sphere, but concave inside surface. 

Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to accommodate, or where oscillating or recurrent tilting movements must be permitted at relatively slow sliding speeds.

Rod Ends

Rod ends is a kind of Spherical Bearings, it consist of an eye-shaped head with integral shank forming a housing and a standard spherical plain bearing, or a spherical plain bearing inner ring, or a spherical plain bearing inner ring and a sliding layer between the bore of the head and the inner ring. As a rule, rod ends are available with left or right-hand female or male threads. Rod ends from Huihao Bearing have the sliding contact surface combinations steel-on-steel, steel-on-bronze, steel-on-PTFE composite material, and steel-on-PTFE fabric.

Rod Ends Requiring Lubrication

Steel-on-steel and steel-on-bronze rod ends have very wear-resistant sliding surfaces and perform well under conditions of lubricant starvation. Rod ends with this sliding contact surface combination require regular relubrication. They are particularly suited for bearing arrangements where heavy alternating loads have to be accommodated.

Maintenance-Free Rod Ends (Rod Ends Requiring No Lubrication)

Rod EndsMaintenance-free (lubrication free) rod ends from Huihao Bearing have two different sliding contact surfaces: steel-on-PTFE composite material and steel-on-PTFE fabric (depending on the diameter of the shaft). Both have very low friction and can be operated without maintenance. They are used for applications where long bearing lives are required without maintenance, or where operating conditions, such as inadequate lubrication or the absence of lubrication make the use of steel-on-steel bearing inadvisable. The maintenance-free bearings are primarily intended for applications where loads are heavy and have a constant direction.

Huihao Bearing also can produce special Spherical plain bearings according to your drawings or samples.
