Trusted & Reliable PTFE Bushings Supplier
High-performance PTFE bushings alternatives with PTFE-lined, metal-backed bushings, and self-lubricating bearings technology.
Sliding-bearing PTFE bushings are a type of self-lubricating bushing made from a synthetic polymer called polytetrafluoroethylene (PTFE). These bushings offer low-friction properties and are highly resistant to wear and corrosion. They are often used in applications where there is a need for high durability and low maintenance requirements.C opposite bushings have a smooth surface that is able to glide easily against the surface of the rotating shaft, which reduces friction and wears. They are also resistant to chemicals, making them ideal for use in harsh environments where chemical exposure is a concern. One of the main advantages of composite bushings is that they are self-lubricating, which means that they do not require additional lubrication from an external source. This can make them a good choice for applications where regular maintenance or lubrication would be difficult or time-consuming. Composite bushings are commonly used in a wide range of applications, including automotive and industrial machinery, aerospace, and medical equipment. They are often used in bearings and other rotating components where low friction, high wear resistance, and long service life are required.

Our PTFE-free bushings are cost-effective and provide exceptional value in the long run.
bushings are commonly used in applications where high loads, low speeds, or oscillating movements are present. They are particularly well-suited for use in harsh or corrosive environments, where conventional lubrication methods may not be practical or effective.
The self-lubricating feature of bushings eliminates the need for external lubrication, which reduces maintenance costs and extends the lifespan of the bearing. The low friction coefficient of the PTFE layer also helps to reduce energy consumption and improve the efficiency of the machinery.
PTFE bushings are available in various sizes and configurations to suit different applications. They can be used in a range of industries, including automotive, aerospace, and marine.
PTFE bushings offer excellent low-friction properties and wear resistance, making them a reliable and effective choice for self-lubricating bearings in a range of applications.

High-performance composite bushings, PTFE-lined bearings, metal-backed bushings, self-lubricating bearings technology.
Steel Bearing is often confused with PTFE lined, metal backed bushings. PTFE-lined bearings are now designed to withstand high speeds and loads, extreme temperatures, corrosive chemicals, and a wide range of other application requirements and environmental factors. composite bushing PTFE-lined bearings replace bearings for five major reasons
1. thinner bearing bushings PTFE-lined bearings
PTFE-lined bearings consist of a metal housing with a PTFE coating
PTFE-lined bearings are composed of a self-lubricating composite polymer compound containing solid lubricant composite. during operation, these sliding wear layers are transferred to the shaft to help reduce the coefficient of friction and wear rate, and to eliminate the risk of bearing-to-metal contact.
2. Stainless steel bearings are more resistant to corrosion and chemicals
Bearings are resistant to corrosion
In applications where water or chemicals are present, PTFE lined bearings with metal housings are backed with stainless steel. in these types of environments, plain steel backed can rust, corrode and contaminate sensitive areas, as well as cause bearing failure. Bearings made of stainless steel are less prone to rust and the self-lubricating material is resistant to chemicals, oils and other corrosive media.
3. Use PTFE lined bearings to save weight
PTFE lined bearings are much heavier than the normal ball bearing option. When using a heavier bearing, regardless of the material, more energy is required to operate the bearing system. This can be a problem, especially in vehicle applications such as automobiles, aerospace applications, recreational vehicles and bicycles.
In comparison, composite PTFE-lined bearing bushings are very light weight, about 90% less than the normal deep groove ball bearing option. The reduced weight reduces fuel consumption and CO2 output and lowers the overall drive force requirements. As a comparison, PTFE-lined bearing bushing is much easier to install. 4.
4. lower friction coefficient
Coefficient of Friction Chart
Due to the low value of PTFE, the coefficient of friction of PTFE-lined bearings is usually very good at the beginning of the bearing’s service life. composite bearing material is a homogeneous mixture of base polymer, reinforced fibers and solid lubricant. Because the lubricant particles are spread throughout the thickness of the bearing, the bearing has a short start-up phase when it engages the shaft surface, after which it maintains a low coefficient of friction throughout the life of the bearing.
How the friction between the sliding bearing and its shaft changes over the life/wear of the bearing.

Oil Free Bushings – Multi-Layer Steel PTFE Bushings (Dry Bush) – Straight Bearing
Different types of oil-free or self-lubricating bushings. They’re used in applications where regular lubrication is not feasible or desired.
- Oil-Free Bushings: As the name suggests, oil-free bushings do not require lubrication to reduce friction and wear. These bushings are made from materials that have inherently low-friction properties, such as certain types of plastic or composite materials. They’re often used in applications where regular lubrication is not practical, such as in food processing or pharmaceutical equipment.
- Multi-Layer Steel PTFE Bushings (Dry Bush): These are a type of self-lubricating bushing that consists of multiple layers. The innermost layer, which is in contact with the shaft, is typically made of a low-friction material such as Polytetrafluoroethylene (PTFE). The middle layer is usually a porous material that has been impregnated with PTFE, and the outer layer is often made of steel for strength and durability. These bushings are also referred to as “dry bushes” because they do not require additional lubrication.
- Straight Bearing: This is a type of bushing that has a straight or cylindrical shape. They can be made from many different materials, including metals, plastics, or composites. They’re often used in applications where the shaft has a linear, rather than a rotating, motion. If made from self-lubricating materials or designed with a multi-layer structure like the steel PTFE bushing, they also could be oil-free.
These oil-free bushings can provide a number of advantages, including reduced maintenance, longer service life, and the ability to operate in environments where traditional lubrication is not possible. However, they may not be suitable for all applications, especially those involving high speeds or heavy loads.
