Angular Contact Spherical Plain Bearings
Angular contact spherical plain bearings are designed to handle combined radial and axial loads due to their spherical shape and angled alignment with the bearing axis. They can only accommodate axial loads in one direction and allow for separate mounting of the rings.
- High Load Capacity
Capable of handling both radial and axial loads simultaneously, ensuring durability under heavy operating conditions. - Self-Aligning
Designed to compensate for angular misalignments, improving reliability in various applications. - Versatility
Suitable for dynamic applications with combined load directions, making them ideal for machinery and automotive uses. - Maintenance-Free Options
Available with PTFE-coated surfaces for lubrication-free operation, reducing maintenance time and cost. - Durable Materials
Made from high-strength steel or other materials to resist wear and extend service life, even under harsh conditions.
AMIGO angular contact 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:
- Heavy-duty construction machinery
- Hydraulic cylinders and systems
- Agricultural equipment
- Industrial automation systems

Angular Contact Spherical Plain Bearings - Designs and Variants
Steel/PTFE FRP Sliding Contact Surface Combination
Bearings with the steel/PTFE FRP sliding contact surface are maintenance-free and provide excellent resistance to wear and friction. They are ideal for applications where long service life and low maintenance are key. These bearings are designated with the suffix F.
Steel/PTFE Fabric Sliding Contact Surface Combination
This combination provides low friction and is maintenance-free, designed for high-performance applications that require smooth, long-lasting operations. It is typically used in environments where lubrication is difficult. Designation suffix TX.
Steel/Steel Sliding Contact Surface Combination (SA)
Bearings with this contact surface combination require regular maintenance but offer robust performance for heavy-duty applications. They can withstand significant load pressures and are designated with the suffix SA.
Steel/Steel Sliding Contact Surface Combination (S)
These bearings are suitable for general heavy-duty use, requiring regular lubrication. They are highly durable and are typically used in applications where high-load capacity and resistance to impact are critical. Designation suffix S.

Frequently Asked Questions (FAQs)
Q: How do Angular Contact Spherical Plain Bearings differ from standard spherical bearings?
A: These bearings have a contact angle that enables them to support both radial and axial loads, unlike standard spherical plain bearings, which primarily handle radial loads.
Q: What is the typical contact angle in Angular Contact Spherical Plain Bearings?
A: The contact angle varies depending on the design but is typically optimized to balance radial and axial load capabilities for smoother operation.
Q: Are Angular Contact Spherical Plain Bearings self-aligning?
A: Yes, they have a self-aligning capability, which helps in compensating for misalignments in applications.
Q: Can Angular Contact Spherical Plain Bearings support axial loads in both directions?
A: These bearings generally support axial loads in one direction, but with double row or specific arrangements, they can support axial loads in both directions.
Q: What are the primary applications of Angular Contact Spherical Plain Bearings?
A: These bearings are used in applications requiring combined radial and axial load support, such as hydraulic cylinders, construction machinery, and automotive components.
Q: What materials are used in Angular Contact Spherical Plain Bearings?
A: They are often made of high-strength steel, with options for PTFE or other coatings for maintenance-free operation.
Q: How are Angular Contact Spherical Plain Bearings lubricated?
