Steel-backed PTFE bushings, also known as Teflon 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 PTFE (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 PTFE 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 PTFE 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 (PTFE) and a mixture of green polymer material, bearing and sliding bearing .

Structure

1. PTFE / 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 PTFE 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
