MQ-10 MQ-10 Carbon Steel Self-lubricating Bushing

With low carbon steel as the backing, sintered bronze as a medial layer, mixed PTFE with fibers as a self-lubricating layer.
Suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics, the transfer film created will protect the mating metal surface.
Suitable for rotary and oscillating movement, high chemical resistance, lower absorption of water, and reduced swelling. Also performs well with lubrication.
( also known as SF-1 or DU)

      Application characteristics

1. Suitable for oilless or few grease working conditions;
2. Long maintenance-free; Long operating life due to low friction;
4. low vibration, low noise, and non-pollution in operation;
5. Thin wall thickness & low weight for the machine with compact design;
6. low hardness of mating shaft can be mated, so the shafts processing is easy;
7. PTFE film is transferred to the mating shaft, to protect the mating metal surface, also improve running properties;
8. lower absorption of water, heat dissipation, and reduced swelling, to keep the exact sizes;
9. Cu or Tin plated in outer Surface, for good anit-corrosion.

Industry Knowledge

Carbon steel self-lubricating bushings, also known as metal-polymer composite bearings or steel-backed bronze powder with PTFE (polytetrafluoroethylene) bushings, are a type of plain bearing that is designed to operate without the need for additional lubrication. These bushings are made of a steel backing with a porous bronze layer impregnated with PTFE (Teflon) and other additives, providing excellent self-lubrication properties.
The carbon steel backing of these bushings provides strength, rigidity, and resistance to corrosion, while the porous bronze layer provides excellent thermal conductivity and shock resistance. The PTFE and other additives in the bronze layer provide low friction and wear resistance, making the bushings ideal for high-load, low-speed, and oscillating motion applications.
Carbon steel self-lubricating bushings are commonly used in applications such as agricultural and construction equipment, automotive suspension systems, and industrial machinery. They offer several advantages, including reduced maintenance and downtime, longer service life, and improved performance in harsh and dirty environments. They can also operate in a wide range of temperatures and are resistant to corrosion.
These bushings are available in various sizes and dimensions to suit different applications and can be customized to fit specific requirements. However, they can be more expensive than other types of plain b
