PTFE Composite PTFE Tin Bronze Copper Layer Sheet Steel Backing

PTFE Composite Bearings, featuring a Tin Bronze Copper Layer with Sheet Steel Backing, are an innovative solution designed for exceptional performance in a wide range of industrial applications.

The PTFE (Polytetrafluoroethylene) composite material offers excellent wear resistance and low friction, ensuring smooth and efficient operation. The Tin Bronze Copper Layer provides additional strength and durability, enhancing the bearing's overall performance.

The Sheet Steel Backing provides robust support and stability, allowing the bearing to withstand high loads and pressures. This combination of materials ensures reliable performance even in harsh environments and demanding conditions.

The PTFE Composite Bearings are easy to install and maintain, reducing downtime and enhancing operational efficiency. They are suitable for use in pumps, motors, and other rotating machinery, where smooth and reliable operation is crucial.

Overall, PTFE Composite Bearings with Tin Bronze Copper Layer and Sheet Steel Backing offer a robust and durable solution for industrial applications that require high performance and long-lasting bearing solutions.

Long maintenance-free operating life due to low friction
In applications where other materials have shown insufficient operating life bushing PTFE Composite dry sliding bearings can be the solution. SKF PTFE Composite is specially designed to operate without lubricant and is particularly suited for high load/medium speed applications.
we offers a full range of cylindrical bushings in accordance with ISO 3547 and DIN1494 as well as flanged bushings, thrust washers and strip
.
viiplus PTFE Composite bearings
offer many features and advantages
such as:
• maintenance-free operation
• very good frictional properties
• high load capacity
• operating temperatures up to 250 °C
• sliding velocity up to 2 m/s
• small operating clearance
Material
PTFE Composite dry sliding bearings
combine the mechanical strength of steel
with the low friction of a PTFE-based
self-lubricating sliding layer. The intermediate layer of porous tin bronze guarantees a strong bond between the backing and sliding surface and also improves the
dissipation of heat generated during operation. The bearing is available in two versions. One with a sliding layer without any lead. This version has the suffix E. Another
version where the sliding layer contains
a minor amount of lead incorporates the
suffix B. To protect the bearings from corrosion the steel backing is tin-plated. All PTFE Composite dry sliding bearings can be machined, except for the sliding surface. However, calibration is possible within certain limits
Main applications 1)
PTFE Composite dry sliding bearings are suitable for applications where the load and self-lubrication requirements
are high.
Examples of applications are:
• automotive applications
• materials handling equipment
• home appliances and consumer goods
• textile machinery
Lubrication
The PTFE-based sliding surface permits
smooth, low-friction operation without
lubrication or maintenance. During the
running-in phase, part of the covering
layer of bearing bushing material PTFE Composite dry sliding
bearings is transferred to the mating surface and forms a physically bonded lubricant film. The presence or continuous supply of
oil or other noncorrosive fluids may be advantageous and improve the performance of these bearings.

Strips Area of Use

A dry running bearing with a low coefficient of friction, good wear properties and sliding characteristics. It can be used in both rotary and oscillating applications

Strips Feature

Flat Strips Plain Bearing It is made of high quality low-carbon steel, and sintered and rolled copper alloy as its surface. It has high fatigue strength, load capacity and impact strength.

Strips Structure

Steel bronze powder with PTFE/Fibres mixture

1. PTFE fibres mixture 0.01-0.03mm, lead free: provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant film.

2. Sintered bronze powder 0.20-0.35mm: provides maximum thermal conductivity away from the bearing surface, also serves Dryslide structural detailas a reservoir for the PTFE-lead mixture.

3. Low-Carbon Steel: provides exceptionally high load carrying capacity.

4. Tin plating 0.002mm: provides good corrosion resistance

Self-Lubricating Multilayer Composite Bushing Life

1). PV Value
PV value is an effective criterion to calculate the service life of sliding bearing. If there is 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 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.

Typical Applications

Can meet the demanding criteria for long life and trouble-free performance with or without lubrication.
