一、What is self-lubricating SF-1 bushing
SF-1 bushing is a three-layer composite set, which is a self-lubricating bushing made of steel plate, spherical bronze powder, and PTFE three-layer composite coil.It is a sliding bearingmade by rolling.
It has the characteristics of low friction coefficient, wear resistance, good corrosion resistance, and oil-free lubrication. The use of this product has the advantages of reducing costs, reducing mechanical volume, avoiding shaft biting, and reducing noise.
二、SF-1 bushing Materials Structure And Thickness
- PTFE layer: 0.01-0.03 mm
- Porous bronze: 0.2-0.3 mm
- Steel backing: 0.7-2.3 mm
- Electroplating layer: Tin-plating about 0.005 mm, or copper-plating about 0.008 mm
三、oil-free bearing SF-1 bushing Characteristics
- SF-1 self-lubricating sleeve has the characteristic of oil-free lubrication, which is suitable for application scenarios that are difficult to refuel.
- It has the characteristics of low friction coefficient, wear resistance and corrosion resistance, and a long service life.
- The coefficients of static friction and dynamic friction are relatively close, which can stabilize the accuracy of mechanical work.
- It can reduce mechanical vibration, thereby reducing noise.
- The liner can form a transfer film during use, which provides protection for the shaft and has low requirements for the shaft, making it more conducive to the machining of parts.
- Thin walled structure, as well as various thicknesses and shapes to support production.
- The steel back can be electroplated with different metal materials, which can be widely used in different application scenarios.
