What is a flanged sleeve bearing?

• Flange sleeve bearing is a kind of sliding bearing with flange edge structure, which generally consists of a shaft sleeve and a flange. The main purpose of this bearing is to support the rotating shaft, and to reduce friction and wear during operation.
• The biggest feature of flange sleeve bearings compared with common sleeve bearings is the flange edge that protrudes. This structure of the flange also has the function of axial positioning, and prevents the axial movement of the bearing during operation.
• Flange sleeve bearings are usually installed in mechanical equipment holes to bear radial and partial axial loads, so they are widely used in industrial equipment.

The main parts of the flange sleeve bearings consist of:

• Sleeve, body
• Edge of flange
• Inner bore sliding surface
• Lubricating film or self-lubricating material

among which are:

• The sleeve part supports the rotating shaft.
• The flange part is used for positioning and fixation
• It is to reduce friction of internal sliding surface

Some high performance flange sleeve bearings will also increase:

• Layer of graphite lubricant
• Copper-containing materials
• PTFE coatings
• Self-lubricating composite film

To increase wear resistance and service life.

• Sliding friction is the main working principle of flange sleeve bearings.
• When the rotating shaft moves inside the bearing, it creates a lubricating layer between the shaft and the bearing, thereby reducing direct metal contact, friction and wear.

The flange part is responsible for:

• Limit axial motion
• Maintain installation stability
• Enhance equipment operational accuracy

Flange sleeve bearings have a simple structure compared with rolling bearings, and are particularly applicable to the working conditions of low speed, high load and frequent start and stop.
 

Flange sleeve bearings have many obvious advantages , and are widely used in the mechanical equipment .

The main features are as follows:

• basic structure
• Simple to install
• High carrying ability
• Quiet Operation
• Lower maintenance cost.
• Ideal for high load situations

At the same time many flange sleeve bearings also have:

• self-lubricating properties corrosion resistant high temperature resistant
• Suitable for complicated industrial surroundings.

Depending on the operating conditions flange sleeve bearings are made of different materials.

Commonly used materials are:

• Copper alloy Brass Bronze Stainless steel Engineering plastic
• Materials of powder metallurgy

The following methods can also be used in some special environments:

• Composite material graphite
• Composite material of PTFE
• Oil-bearing material

To meet the requirements of maintenance free or special lubrication.

Flange sleeve bearings are used in a variety of industries including:
Many mechanical equipment and industrial fields use flange sleeve bearings extensively.

Common examples of industries include:

• Construction machinery Agricultural machinery Automobile manufacturing
• Motor equipment for packaging machinery
• textile machinery, conveying equipment
• 

Flange sleeve bearings are used for support and positioning in many devices because of their stable structure and easy installation.
