Thrust Spherical Plain Bearings
Thrust spherical plain bearings feature a convex spherical surface on the shaft washer and a matching concave spherical surface in the housing washer. They are designed to handle primarily axial loads but can also manage combined radial and axial loads. The radial load component should not exceed 50% of the axial load. For larger radial loads, combine thrust bearings with radial bearings in the GE dimension series.
- High Load Capacity
Designed to handle heavy axial loads in both directions. - Misalignment Accommodation
Allows for compensation of angular misalignments between shaft and housing. - Maintenance-Free Options
PTFE-lined bearings offer maintenance-free operation with reduced friction. - Durable Construction
Made from high-quality materials like steel and PTFE for long service life. - Sealed and Open Variants
Available in sealed versions for protection from contaminants, or open versions for specific applications.
AMIGO thrust spherical plain bearings are widely used in various industries. Their availability matches their versatility across numerous applications in a wide range of designs, variants, and sizes. Examples of applications include:
- Hydraulic cylinders
- Construction machinery
- Agricultural equipment
- Heavy-duty industrial machinery
- Automotive suspension systems

Thrust Spherical Plain Bearings - Designs and Variants
Steel/PTFE FRP Sliding Contact Surface Combination (Designation Suffix F)
Steel/PTFE FRP sliding contact surface combinations are maintenance-free and offer excellent resistance to corrosion. These bearings are ideal for applications that require high durability and a low coefficient of friction under both dry and lubricated conditions.
Steel/PTFE Fabric Sliding Contact Surface Combination (Designation Suffix TX)
This combination offers a maintenance-free solution with a low friction coefficient, suitable for high load applications. The PTFE fabric sliding contact surface ensures reduced wear and increased service life in demanding conditions.
Steel/Steel Sliding Contact Surface Combination (Designation Suffix SA)
Bearings with steel/steel sliding contact surfaces require maintenance but provide high load-carrying capacity. These combinations are robust and designed for heavy-duty applications where durability is essential, especially under challenging operational environments.
