What are the types of flange screw bearings?

Flange screw bearings, commonly referred to as flange bearings or flange mounted bearings, are used to support shafts and offer a secure mounting surface with a flange. There are several types, each suited to different applications.

Flange screw bearing type

1. 2-Bolt Flange Bearings

Description: These have a circular flange with two mounting holes.

Common Use: Used in light-duty applications where space is limited.

2. 3-Bolt Flange Bearings

Description: These have a triangular flange with three mounting holes.

Common Use: Provide a more stable mounting than 2-bolt versions, often used in agricultural and industrial machinery.

3. 4-Bolt Flange Bearings

Description: These have a square or rectangular flange with four mounting holes.

Common Use: Used in heavy-duty applications due to their secure and stable mounting.

4. Piloted Flange Bearings

Description: These have a central pilot that fits into a corresponding hole in the mounting surface for added alignment.

Common Use: Provide precise alignment and are often used in high-precision machinery.

5. Pressed Steel Flange Bearings

Description: Made from pressed steel, these are lightweight and economical.

Common Use: Suitable for light-duty applications where cost is a concern.

6. Cast Iron Flange Bearings

Description: Made from cast iron, these are more robust and durable.

Common Use: Used in heavy-duty applications where strength and durability are essential.

7. Plastic Flange Bearings

Description: Made from plastic materials like nylon or PTFE, offering corrosion resistance.

Common Use: Ideal for applications where chemical resistance and low friction are required.

8. Stainless Steel Flange Bearings

Description: Made from stainless steel, offering high corrosion resistance.

Common Use: Used in food processing, marine, and other environments where corrosion is a concern.

9. Self-aligning Flange Bearings

Description: Designed to allow for slight misalignment of the shaft.

Common Use: Used in applications where alignment may be difficult or where shaft deflection occurs.

These types of flange screw bearings can be further customized with different types of seals, lubrication options, and bearing materials depending on the specific requirements of the application.
