Oil Free Bushings – Multi-Layer  Bushings (Dry Bush) – Straight

CUSTOM, MADE TO ORDER, PRECISION MACHINED PARTS

Composite product consisting of three layers: steel-backed metal layer, sintered bronze layer and filler added PTFE layer.

Sleeve bushings crafted from PTFE are enhanced with metal reinforcement to accommodate heavy-duty applications, ensuring an extended and dependable lifespan. It is advisable to choose PTFE for sleeve bearings due to its exceptional load-bearing capabilities. If you appreciate the noise-reducing and self-lubricating features of plastic but need a component that can handle rigorous use, this is an ideal choice. Opting for a lubricated material like PTFE eliminates the necessity for additional lubrication. Our PTFE series features a self-lubricating PTFE blend that is fortified with metal for extra strength.

PTFE (polytetrafluoroethylene) pivot bush materials often include a metal backing, such as steel or bronze, combined with a PTFE layer. This combination offers an excellent balance of performance characteristics, including low friction, self-lubrication, corrosion resistance, and high load-carrying capacity.

These materials are commonly used in industries where low friction, self-lubrication, and chemical resistance are critical requirements, such as automotive,  food processing, and chemical processing. 

The metal backing provides structural support and mechanical strength, while the PTFE layer contributes to low friction, self-lubrication, and chemical resistance.

Now, let’s explore the vital connection between bearings and bushings: the sleeve bearing.

Commonly known as bushings, journal bearings, or plain bearings, sleeve bearings boast the most straightforward design in the bearing family. These cylindrical components are prevalent in systems with rotating or sliding parts. Available in various materials, plastic stands out as the most cost-effective option.

While all-metal bearings offer a low friction coefficient, they might produce noise at elevated speeds. Steel sleeve bearings can be lubricated to mitigate this issue. Alternatively, for a quieter, low-maintenance solution with consistently low friction, opting for self-lubricating materials like PTFE is beneficial.

A cylindrical sleeve bearing is perfect for handling radial loads, whereas a flanged sleeve bearing is designed to manage axial loads. For handling high loads, pairing thrust washers with a cylindrical bearing is an effective strategy.
