Flange Bushing
Flange bushing introduction
UM flange bushing has an additional flat washer attached to the original bushing outer ring to form a single piece. In the mechanical engineering part, it is loved by many engineers, and the design of the positioning mechanism is omitted. Even if the products of other brands look the same, we are still not inferior to them in terms of performance and quality.
Using our UM’s proprietary formulation technology, the self-lubricating composite material gives the bushing a very low coefficient of friction, while significantly improving wear resistance and service life, allowing for long-term stable operation in a wide range of industries and achieving strength and rigidity comparable to that of metal.

The basic structure of the flange bushing
Flange lining is a simple design combined with a lining, plus positioning functionality engineering ingenuity, which is beneficial to reduce costs. Its core purpose remains the same: to provide a low-friction sliding interface between the shaft and the hole, while absorbing vibration and protecting the mechanism. The following six points are the basic structure of flange bushings:
Inner Diameter (ID)
In contact with the rotating axis, most of them still have very fine gaps, which require good surface finish and wear resistance. It can be designed with a smooth side or with lubrication grooves (grooves).
Outer Diameter (OD)
Press into the inlet hole to form a fixed fit, called interference fit. Some designs include external grooves to facilitate positioning, prevent displacement, or lubrication.
Height (H) or Length (L)
Determine the contact area of the shaft lining and the stability of the shaft deflection. Long or short can be selected according to the application requirements, which is generally proportional to the overall shaft length.
Wall Thickness (t)
Appropriate thickness affects the bearing capacity and shock absorption effect. Thin-walled design can reduce weight, but be aware of the risk of deformation; In addition, continuous increase in thickness does not mean that the bearing capacity can be continuously increased, unless there is a special purpose, excessive thickness is an unnecessary cost waste.
Chamfer (C)
Unified design, the top outer diameter is the guide corner, which helps to easily install into the hole; The bottom of the inner diameter is the guide corner, which helps to easily fit the shaft into the shaft liner.
Flange (F)
One side expands into a disc shape to prevent axial movement of the bushing. It provides additional positioning and bearing surfaces, which is quite convenient to use.
Numbering Description
We usually use numbers and words to represent the size of the bushing, similar dimensions, not necessarily every bushing is an integer. For example, for cylindrical bushings, you will see DBH as the beginning of the number. For flange type bushings, you will see DFB as the beginning of the number.
Then, the subsequent numbers represent the inner diameter, outer diameter, height, flange outer diameter, and version, for example, 12 in the DFB1214042001 represents 12 mm in the inner diameter and 14 means 14 mm in the outer diameter. 04 is represented by the height of 4 mm, 20 is indicated by the flange OD of 20 mm, and 01 is indicated by the version.
The values we provide are approximate and not integers, for example, 14 is likely to be 14.20mm. Therefore, you need to click on the link to enter the product industry to confirm the dimensions and tolerances in more detail.
