SF-1D Hydraulic Bushing, SF-1S Stainless Steel Bushings
Material: Steel+bronze+PTFE
The PTFE bushing is made of steel plate, sintered spherical bronze powder in the middle, rolled ptfe and mixture on the surface. It has the characteristics of low friction coefficient, wear resistance, good corrosion resistance and no oil lubrication. It can reduce the cost, reduce the size of the machine, avoid the phenomenon of shaft biting and reduce the noise. PTFE Bushings have been widely used in various machinery sliding parts such as: printing press, textile machine, tobacco machinery, automobile, motorcycle and agricultural and forestry machinery.

Dry sleeves are bushings or sleeves that are designed to fit between the seat in the housing and the shaft. The main function of these products is to separate the rotating parts of the moving structure to prevent them from coming into contact with each other.
Plain bushings, also known as radial bearings, are designed to facilitate the rotation of elements. Crafted from stainless steel, these bushings boast an extended lifespan. Their deployment minimizes the heating of frictional components, thereby enhancing durability. Lubricants are strategically placed between the shaft and the bushing’s bore to enable smooth operation.
These bushings, with an internal diameter starting at 6 mm, feature a cylindrical design and are capable of enduring high radial loads, making them ideal for industrial machinery and tools. Customers can acquire these parts either through online shopping or by placing custom orders.

DP4 composite bushings offer good wear and low friction performance over a wide range of loads, speeds, and temperatures in dry running conditions. We offer high-performance, maintenance-free solutions for many applications.
The SF-1D hydraulic sleeve was developed on the basis of the SF-1P taking into account the principle of operation of the oil pump and shock absorber.
SF-1D hydraulic bushing is developed on the basis of SF-1P while taking into account the working principle of the oil pump and shock absorber. It shows better performance in working conditions without oil lubrication. produced abroad. In addition to covering the same usage of SF-1P, SF-1D in particular frequently adapts to reciprocating motion with high lateral force. It is a trend to gradually replace SF-1P with SF-1D, the latter will cover wide applications in automobiles, engine shock absorbers,s and oil pumps, etc.
CHARACTERISTICS
- Good wear and low friction performance over a wide range of loads, speeds, and temperatures in dry running conditions
- Very good performance in lubricated applications particularly in marginally lubricated applications
- Suitable for linear, oscillating, and rotating movements
- Lead-free material match RoHS specifications.
COMPOSITION
Metal-Polymer Composite Bushing Material
Steel Backed Bushing + Porous Bronze Sinter + PTFE + Fillers
1. PTFE/Fibre mixture thickness 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide-type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides Max. thermal conductivity away from the bearing surface also serves as a reservoir for the PTFE-Fibre mixture.
3. Low-carbon steel, gives exceptionally high load carrying capacity, and excellent heat dissipation.
4. Copper/Tin plating thickness of 0.002mm, provides good corrosion resistance

APPLICATION ADVANTAGES
-
No oil lubrication or little oil lubrication. It is suitable for situations where refueling is impossible or difficult and can be used without or with little maintenance.
-
Good wear resistance, small friction coefficient, long service life.
-
can be used in the range of -195℃~+280℃.
-
Good running performance, low noise, no pollution.
-
A thin wall structure, lightweight, can reduce the volume of machinery.
-
In operation can form transfer film, play a protective role on the grinding shaft, no shaft biting phenomenon.
-
The hardness of the grinding shaft is low, and the shaft without quenching and tempering treatment can be used, thus reducing the processing difficulty of the relevant parts.
-
No water absorption, oil absorption thermal expansion coefficient is small, good heat dissipation, size stability.
- The back of the steel can be plated with a variety of metals, so it can be used in corrosive media and will not rust.
APPLICATIONS
Due to the performance characteristics under dry and lubricated operating conditions, DP4 and DP4B bearing materials are widely used in a wide range of automotive and industrial applications, such as:
