Radial Spherical Plain Bearings
Radial spherical plain bearings feature an inner ring with a convex outside diameter and an outer ring with a concave inside surface. They are ideal for bearing arrangements requiring alignment movements between the shaft and housing, or where oscillating, tilting, or slewing movements occur at slow sliding speeds, often under heavy loads.

Radial Spherical Plain Bearings - Designs and Variants
Standard Steel/Steel Sliding Contact Surfaces
Standard steel sliding contact surfaces are designed for durability and require regular maintenance. They are commonly used in applications where heavy loads are present. Designation suffixes E and ES indicate the need for maintenance.
Heavy-Duty Steel/Steel Sliding Contact Surfaces with Multi-Groove System
Heavy-duty steel sliding contact surfaces feature a multi-groove system that enhances load distribution and wear resistance. These surfaces are ideal for high-load applications and require maintenance. Designation suffix ESL refers to this design.
Steel/PTFE Fabric Sliding Contact Surfaces
Steel/PTFE fabric sliding contact surfaces provide excellent performance in maintenance-free applications. The PTFE fabric reduces friction and increases wear resistance, making them ideal for environments requiring reduced maintenance. Designation suffix TX applies to this type.
Steel/PTFE FRP Sliding Contact Surfaces
Steel/PTFE FRP sliding contact surfaces combine steel with a PTFE coating reinforced with fiberglass. These maintenance-free surfaces offer high performance in harsh environments. Designation suffixes FBAS and FS indicate this style.
Steel/PTFE Sintered Bronze Sliding Contact Surfaces
Steel/PTFE sintered bronze sliding contact surfaces are maintenance-free and combine the strength of steel with the low friction of PTFE. The sintered bronze offers enhanced load capacity and longevity. Designation suffix C indicates this surface type.

Frequently Asked Questions (FAQs)
Q: How do Radial Spherical Plain Bearings differ from other bearings?
A: These bearings feature a spherical inner ring that provides greater misalignment flexibility and load-bearing capabilities compared to standard rolling bearings.
Q: What are the mechanical properties of Radial Spherical Plain Bearings?
A: They are known for their high radial load capacity, durability under misalignment, and resistance to wear in heavy-duty applications.
Q: What materials are Radial Spherical Plain Bearings made from?
A: These bearings are often made from hardened steel, with some models incorporating PTFE liners or coatings for maintenance-free performance.
Q: Can Radial Spherical Plain Bearings accommodate axial loads?
A: While primarily designed for radial loads, some variants can also handle limited axial loads depending on the specific application.
Q: How do Radial Spherical Plain Bearings perform under high-stress environments?
A: They perform exceptionally well in environments that require durability and the ability to handle misalignment and heavy loads, such as in construction and mining machinery.
Q: What are the typical applications of Radial Spherical Plain Bearings?
A: These bearings are commonly used in agricultural equipment, hydraulic cylinders, and heavy industrial machinery, where high load and misalignment conditions occur.
Q: What maintenance is required for Radial Spherical Plain Bearings?
A: Maintenance depends on the type. Bearings with PTFE liners are maintenance-free, while steel-on-steel bearings may require regular lubrication to prevent wear.
Q: How is the load capacity of Radial Spherical Plain Bearings determined?
A: The load capacity is determined by the bearing’s size, material, and design, which allows it to handle heavy radial loads and compensate for misalignment.
Q: How do I choose the right Radial Spherical Plain Bearing for my application?
A: Selection depends on load requirements, operational speed, misalignment tolerance, and whether maintenance-free or lubricated bearings are preferred.
