Products Description
This Spherical Plain Radial Bearing has an inner ring with a spherical convex outer diameter and an outer ring with a spherical concave inner diameter. The inner ring is installed in the matching outer ring without any rolling element to adapt to unique applications. Its design makes it particularly suitable for bearing arrangement, which can well adapt to the alignment movement between shaft and shell, or it must be able to oscillate or repeatedly tilt or swing at a relatively slow sliding speed.
Features
This Spherical Plain Radial Bearing is made of high quality hardened steel, which has high strength and good rigidity after precise grinding, which can provide you with consistent and reliable performance during use. At the same time, its surface is coated with molybdenum disulfide, after careful treatment, the friction of the contact surface can be minimized to ensure smooth operation. In addition, we can also provide you with customized orders according to your needs, including special materials, gaps, surface finish or configurations to adapt to unique applications.

Custom Spherical Plain Bearings
Custom Spherical Plain Bearings for OEM Applications
Standard sizes are not always the right solution for industrial equipment. If your application requires a non-standard bearing, we can manufacture spherical plain radial bearings according to drawings, samples, or application requirements.
Available customization may include:
- Non-standard bore or outside diameter
- Special bearing width
- Different internal clearance
- Special sliding contact material
- PTFE or other lining options
- Customized lubrication grooves or holes
- Right-hand or left-hand thread
- Special surface treatment
- Sealing configuration
- Special packaging and labeling
- OEM branding
For a quotation, send us the bearing drawing or the basic dimensions. If a drawing is not available, provide the shaft diameter, housing dimensions, load, movement, speed, temperature, and working environment. Our engineers can review the
requirements and recommend a suitable configuration.
Applications
Spherical plain radial bearings are commonly used in mechanisms where controlled oscillating movement and radial load support are required.
| Industry | Typical Application |
|---|---|
| Agricultural Machinery | Linkages, hydraulic mechanisms, implements and pivot points |
| Mining Equipment | Heavy-duty linkage and articulated mechanisms |
| Conveying Equipment | Pivoting rollers, linkage assemblies and support mechanisms |
| Textile Machinery | Slow oscillating mechanisms and linkage systems |
| Packaging Machinery | Moving arms, joints and positioning mechanisms |
| Printing Machinery | Pivoting and oscillating components |
| Food Processing Equipment | Linkage systems and low-speed moving assemblies |
| Chemical Equipment | Mechanical joints where the selected material is compatible with the environment |
| Construction Equipment | Articulated joints and heavy-load mechanisms |
| General Industrial Machinery | Mechanical linkages, pivots and oscillating connections |
The bearing should be selected according to the actual load, oscillation angle, movement frequency, lubrication condition, temperature, contamination level, and required service life.
FAQ
1. What is a spherical plain radial bearing?
It is a plain bearing with a spherical sliding contact between the inner and outer rings. It is mainly used for radial loads and applications involving oscillating or tilting movement.
2. Does a spherical plain bearing need lubrication?
Some types require regular lubrication, while maintenance-free types use self-lubricating sliding materials. The choice depends on the bearing design and working conditions.
3. What is the difference between an open and 2RS spherical plain bearing?
An open bearing has no sealing arrangement. A 2RS bearing has seals on both sides to help protect the sliding contact from dust, dirt, and moisture.
4. Can you supply custom spherical plain bearings?
Yes. We can provide customized dimensions, clearance, sliding materials, seals, surface treatment, and other specifications based on drawings or application requirements.
5. What information is needed for a quotation?
You can send us the bearing number, drawing, dimensions, required quantity, or application information. For a new application, load, movement, speed, temperature, and working environment are also helpful.
