The SF-1D Bronze Base Ptfe Sleeve Bearing is a high-performance bearing specifically designed for the demanding applications in the metallurgical and steel industry. This bearing combines the durability and strength of a bronze base with the exceptional lubrication and wear-resistant properties of Ptfe (Polytetrafluoroethylene).

The bronze base provides excellent heat dissipation and resistance to corrosion, ensuring that the bearing can withstand the high temperatures and harsh environments commonly found in metallurgical and steel plants. The Ptfe sleeve, on the other hand, offers exceptional lubrication characteristics, reducing friction and wear between moving parts.

The SF-1D Bronze Base Ptfe Sleeve Bearing is also designed for easy installation and removal, making it a convenient choice for applications where frequent maintenance or replacement is necessary. The precision manufacturing ensures a tight and secure fit, minimizing movement and vibration during operation.

The bearing's durability and reliability make it a cost-effective solution for the metallurgical and steel industry. It can handle the heavy loads and high speeds required in various applications, such as rolling mills, conveyors, and other industrial machinery.

In summary, the SF-1D Bronze Base Ptfe Sleeve Bearing is a high-performance bearing that offers exceptional durability, corrosion resistance, and lubrication properties for the demanding applications in the metallurgical and steel industry.

Self-lubricating Bearings

Self-lubricating Bearings is wall wrapped bearing made of triple layer composites material which consists of a steel backing,a sintered porous bronze particles interlayer and calendared with PTFE and Pb mixture as surface layer,It is of low friction cofeeicient,anti-wear,anti-corrosion and can be used without oil,or only a trace of oil os needed.moreover,it is of low cost,low vibration and low noise,compact and light,like POM BUSHINGS widely applied in various sliding articles of different kind of machines,Such as textile machines,tobacoo machines,hydraulic vechicles,antomobiles,agriculture and forests machinese and soon.

· VSB-11

Sf-1b bronze base bearing is based on tin bronze, intermediate sintered bronze ball powder, surface rolling PTEE and high temperature filling material.

It has a high safety factor, especially in places where continuous work cannot be stopped and high temperatures cannot be refuelled. At present, it is widely used in metallurgical and steel industry, continuous casting billet rolling road, high temperature furnace front equipment, cement grouting pump and spiral conveyor. It can be a combination of the outer wave combination, and can also be made to turn the edge, to reach the end face, the inner hole and the effect of friction.

The rolling part of the bridge supports the replacement of the pure PTFE board with the products of sf-1b wear-resistant layer. Meet the requirements of 130N/mm squared.

· Very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions

· Suitable for lubricated applications

· Suitable for linear, oscillating and rotating movements

· Bronze back offers improved corrosion resistance in humid/saline environments

· Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surface, suitable for rotary and oscillating movement. Very high chemical resistance, low absorption of water and swelling, also performs very good lubrication feature, the bronze backing provides the improved corrosion resistance comparing with VSB-10.

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. Bronze backing, provides exceptionally high load carrying capacity, excellent heat dissipation and very good corrosion resistance.
