Sliding bearing bushing function
The working principle of PTFE is to protect the shaft and housing and prevent damage, failure, and friction in the rotating system of different industrial equipment.
Sliding bushings work successfully even where bearing strength and good shaft steering are required. Because the bushings are manufactured in a monolithic form, they are more resistant to axial deficiencies and are very easy to install. Current technology allows the use of common bushings, and until recently it was not necessary to manufacture bearings.
The sliding sleeve is a combination of composite materials and winding fibers. They come in several different types – depending on the application. Each model differs from the other in the elements used for its construction and in the design itself.
Sliding sleeve
Sliding bushings made of composite materials are dry bushings made of three layers of composite materials. They’re perfect for rotating and swinging motion. They are extremely resistant to high radial loads. They don’t need lubrication, so they’re basically completely maintenance-free. They are most often used when building space is limited.
Sliding Bushings – What’s worth knowing about them?
The sliding sleeve is a dry sliding sleeve, also made of three layers of composite material. They are used when there is rotation, oscillation, and linear motion under radial loads. They are also maintenance-free and used when building space is limited. They can also be used when there is a risk of misalignment, edge loads, and high levels of contamination.
Flanged bushing
A flange sleeve made of composite material is a sleeve with a flange on one side. Like previous models, these are made of three layers of composite material. They are used for simultaneously rotating and swinging motion under load rhyming and axial unidirectional. Don’t need… They are lubricated and completely maintenance-free.
Firmware winding fiber sleeve
The bushings are made of a composite material made of coiled fibers. They are used when there is rotational and linear motion with high radial loads, and when alternating, shock or swing loads are present. They are also used in situations where high side loads are possible.
Longitudinal washer
The longitudinal pad is made of three layers of composite material. They are used in bearing configurations to provide axial alignment. They require no extra lubrication and are maintenance-free.
Strip – its structure and application
Strip is made of three layers of composite material. They have embossing, bending, and cutting options, but can also be adapted to the needs of specific applications. They are used anywhere there is dry sliding friction.

Wear-resistant
Self-Lubricating Multilayer Composite Bushing is of excellent anti-abrasion performance, mainly due to the particular molecule structure of PTFE. The abrasion process can be generally divided into three phases, so there are kinds of friction coefficients. See the right graph:
1. “Running-in” phrase: PTFE compound on the bushing is transferred to its mating surface and forms a lubricating film. At this phase, the friction coefficient is bigger, thus the abrasion pace is very quick. See the curve shown in area I of the graph.
2. “Stabilization” abrasion phrase: After the “Running-in phase”, the friction happens between PTFE and PTFE, thus the friction coefficient is smaller and keeps steady. As a result, the wear rate is low and steady. See the curve shown in areaⅡof the graph.
3. “Sharp” abrasion phrase: As PTFE in the porous layer is slowly consumed up, not enough lubricant can be supplied to the gliding media. The friction coefficient and wear rate will rapidly rise. When 70% of the bronze surface is exposed, the service life of Self-Lubricating Multilayer Composite Bushing closes to its end. See the curve shown in area Ⅲof the graph.
PV value is an effective criterion to calculate the service life of Self-Lubricating Multilayer Composite Bushing. If there is a need to prolong the service Life, PV value must be reduced.2). Ambient Temperature
The higher the working temperature is, the shorter the life of the products would be.3). Quality of the Mating Surface
Service life Self-Lubricating Multilayer Composite Bushing can be obviously prolonged if its mating axis is made by alloy steel or is plated by hard chrome and with surface Roughness Ra=0.4~0.63.
