Cojinetes de fricción
viiplus fabrica cojinetes de fricción en diversos diseños y de distintos materiales. Por consiguiente, VIIPLUS ofrece una amplia gama de cojinetes de fricción disponibles en existencia.
Los cojinetes de fricción son adecuados para movimientos giratorios, oscilantes y lineales, mientras que los cojinetes de fricción rectos (cilíndricos) pueden soportar solo cargas radiales, y los cojinetes de fricción con pestaña pueden soportar cargas radiales y axiales en un sentido.
Cada una de las combinaciones de material y diseño del cojinete de fricción tiene unas propiedades características que hacen que el cojinete sea especialmente adecuado para determinadas aplicaciones.
Stainless steel bushings VS ordinary carbon steel bearings
Bearing steel generally has a high carbon content to enhance wear resistance, while stainless steel generally has a high Cr content of more than 12%, mainly in order to make use of its corrosion resistance. Compared with ordinary bearings, stainless steel bushings not only have obvious advantages in material, but also in process, precision control, more strict than ordinary bearings.
In the working process, stainless steel bushing work steadily, low noise, corrosion resistance, widely used.
Compared with ordinary bearing steel, stainless steel bushings with (ptfe) coating have stronger rust and corrosion resistance.
Plain bearing (Cojinete de deslizamiento)
Curabitur non nulla sit amet nisl tempus.
A plain bearing, also known as a sliding contact bearing or slide bearing, represents the most basic form of bearings. It consists solely of a bearing surface, with no rolling elements involved. In this design, the journal simply glides over the bearing surface. The most fundamental example of a plain bearing is a shaft rotating within a hole.

Typical Application For PTFE Bushing
The stainless steel corrosion-resistant friction bearing is a robust and durable component designed for challenging environments. This bearing is constructed from stainless steel, featuring a core of sintered alloy powder renowned for its resistance to corrosion. Its surface is expertly coated with Ptfe, a material known for its exceptional resistance to various corrosive agents. This innovative design ensures the bearing’s resilience against oil, acids, alkalis, and seawater, while also providing superior wear resistance. Notably, the surface PTFE material is lead-free, making it safer and more environmentally friendly.
This bearing is particularly well-suited for use in industries where resistance to corrosion and chemical exposure is paramount. It finds extensive application in food and beverage machinery, where hygiene and resistance to various substances are essential. Additionally, it is ideal for flow pumps and valves handling acidic and alkaline chemical mediums, pharmaceutical machinery, printing machinery, and chemical machinery. Its robust construction and corrosion-resistant properties also make it an excellent choice for marine industry applications, where it can efficiently function as a reliable and long-lasting sliding part.
Sleeve bearings are cylindrical in shape and are used in applications requiring a high load capacity, like electric motors and gearboxes.
