Steel-backed bushings, also known as ptfe bushings, are a type of precision mechanical component commonly used in various industrial applications. These bushings feature a steel backing that provides excellent mechanical strength and stability, while the (Polytetrafluoroethylene) lining offers excellent chemical resistance, low friction, and long-lasting wear resistance.

The customized size option allows for precise fitment in a wide range of machinery and equipment. Wh you need bushings for high-speed rotating shafts, linear motion guides, or any other application, these bushings can be tailored to meet your specific requirements.

Manufactured in China, these steel-backed bushings offer a cost-effective solution while maintaining high quality and performance. Chinese suppliers have extensive experience in manufacturing precision mechanical components and can provide reliable products that meet international standards.

In summary, steel-backed bushings with customized sizes, supplied by China, are an excellent choice for industrial applications that require high performance and durability. Wh you're looking to replace worn-out bushings or upgrade your equipment with improved performance, these bushings are worth considering.

Self Lubricating Plain Bearing

alternative MU(SF-1,SBT,SKF PCM)Steel Backed Bushings,high performance  rings in steel, environmental protection is based on a steel substrate, medium bronze powder, a spherical sintered surface rolling four ethylene () and a mixture of green polymer material, bearing and sliding bearing .

Structure

1. / Pb composition, 0.01-0.03 mm, anti-abrasion material, which forms a lubrication film to protect the shaft during the machine in operation.

2.bronze powder layer, 0.2-0.35 mm, which further strengthens the combination of the steel sheet and the layer. Bronze has good thermal conductivity. It can transfer the heat it produces

3.during operation more quickly.

4.Low-carbon steel, which improves load capacity and heat transfer.

5.Copper / tin coating layer, anti-corrosion.

Application

Oil-free or minimal oil condition, maintenance-free or fair need a little maintenance.
Resists abrasion, low coefficient of friction, long service life.
Operating in -190 ℃ ~ + 280 ℃.
Easy to mend, silent, non-polluting.
Thin, light wall, which can reduce the volume of the machine.
Formation of a film transferred during operation to protect the tree.
Low demand on the tree, even without surface hardness treatment, which reduces the cost of the coupling components.
No absorption to water/oil,small coefficient of thermal emption,good thermal conductivity and size stability.
The back of the steel strip can be plated with various metal,anti-corrosion.
The products now are used in sliding components of different
machines,such as auto machines,piston pump,gear pump,textile
machine,auto-sides machine,injection machine,sports machine,office
