Perforated wrapped bronze bushes are widely used in industrial applications due to their high load capacity, self-lubrication properties, low friction characteristics, and corrosion resistance. They are ideal for applications requiring long bearing life without continuous maintenance and are commonly found in various industries such as construction, mining, agriculture, and automotive sectors.
Wrapped bronze bushes are constructed by sintering bronze material with fine pores filled with oil or grease under vacuum or pressure. They are then wrapped with a layer of PTFE for self-lubrication and wear resistance. These bushes operate on the principles of hydrodynamic lubrication, offering corrosion resistance, cost-effectiveness, and high load capacity. They find applications in shock absorbers, electric motors, industrial machinery, pumps, compressors, and gearboxes. These bushes are designed to reduce installation space, protect against contamination, and extend service life after greasing. They are suitable for various applications such as hoisting machines, construction equipment, automobiles, tractors, trucks, machine tools, and mineral engines. Wrapped bronze bushes are cost-effective compared to other bearing types and offer advantages like self-lubrication, low friction, high wear resistance, and corrosion protection
Specific types of bronze bushings, namely BRO-MET, FB090, BRM10, and WB800. These are specialized bushings often used in various machinery due to their durability and superior wear resistance.
Bronze bushings are made from bronze and feature built-in lubricant reservoirs. This design significantly reduces the likelihood of the component being deprived of lubrication and becoming defective. Such a configuration ensures a long service life for the bushing and thus helps protect friction mechanisms of the equipment from overheating and failure. Bronze bushings are resistant to aggressive environments. They are suitable for use in machinery and industrial equipment and are characterized by low operational noise.
The inner diameter of the bushings available in the “PromBering” catalogue ranges from 10 mm, with the outer diameter starting from 12 mm. They come in a cylindrical design. The production uses a bronze alloy that meets international standards DIN 17662.
In summary, bronze bushings are renowned for their durability, ability to work in harsh environments, and their capacity to maintain lubrication, which reduces maintenance and extends the lifespan of the equipment in which they are used.
Bronze bushings, in general, are preferred in industrial applications because of their excellent load-bearing capabilities and resistance to wear and tear. They’re especially useful in high-load, high-temperature situations where other materials might fail or degrade more rapidly.
- Bronze: This is a range of self-lubricating, sintered bronze bushings. The bronze base offers excellent load-bearing capacity, and the bushings have a porous structure that can be impregnated with oil or another lubricant to reduce friction.
- FB090: Also known as wrapped bronze bushings, these are made from bronze strips with oil-filled holes or pockets. The oil provides self-lubrication, reducing friction and wear. They are widely used in construction machinery, agricultural machinery, and other high-load applications.
- BRM10: These bushings are made of high-strength brass with embedded solid lubricants, typically graphite. They are designed for high-load, slow-moving applications, and the solid lubricant allows them to operate without additional lubrication.
- WB800: These are self-lubricating bushings made from bronze with an embedded solid lubricant. They’re well suited to situations involving heavy loads and low speeds and perform well in environments where traditional lubrication is difficult or impossible.
In summary, these bushings provide a reliable and maintenance-free solution for a variety of demanding applications. Their self-lubricating features reduce maintenance requirements, extend equipment lifespan, and help improve the overall efficiency of the machinery in which they are installed.
