Permaglide® plain bearings are bearings for very small radial or axial design envelopes. These products are available as bushes, flanged bushes, thrust washers and strips and in two groups of materials. The bushes are available not only in metric sizes but also in inch sizes.
Bushes, washers and strips are supplied in the maintenance-free Permaglide® P1 or the low-maintenance P2. Flanged bushes are made from the maintenance-free Permaglide® P1.
Embodies the product characteristic of a permanently, low-wear gliding. By applying a plastic material onto a metallic base alloy, a lowfriction matrix that unites favourable tribological properties with the load carrying properties and thermal conductivity of metals is obtained. The use of solid lubricants in the plastic matrix makes it possible to use Permaglide® bearings in applications without oil- and grease lubrication.
Depending upon customer requirements and specific applications, a number of maintenance-free and lowmaintenance materials are available with identical microstructure. A porous bronze sinter structure applied to a steel or bronze back and is impregnated with the respective plastic mix. The solid lubricant produces a film between the sliding surfaces. It attributes to low-noise operation at constant speeds and low coefficients of friction throughout the entire service life of the component. This is achieved by means of a mixture of PTFE (Poly Tetra Fluoro Ethylene) with wear-retardant and thermally conductive additives.
It is not possible to find the desired solution for plain bearing applications with products made of maintenance-free materials for all duties and applications. For such duties and applications, low-maintenance materials are available. In this case, the sliding surface
taking up the wear load is formulated from a PVDF (Polyvinylidene Fluoride) matrix.
To reduce the coefficient of friction and improve thermal conductivity, special additives are mixed into the matrix. In addition, the surface of the sliding layer may optionally be equipped with lube bore relieves to accommodate grease or oil.

Wrapped bronze bearings are ideal for applications where there are high levels of contamination. Their running surface is provided with diamond-shaped lubrication pockets or a hole pattern. The lubrication pockets must be filled with grease when the bearing is installed. The wrapped bronze bearings are produced according to the ISO 3547.
The AST090 Series Bushings are wrapped of a cold formable homogenous bronze (CuSn8), which will obtain exceptional material properties. The standard sizes are fitted with diamond shaped lubrication indents on the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film in the startup movement and subsequently reduce the startup friction. The material is suitable for the construction and agriculture industries where high load and slow movement are occurring.

They are used not only in mechanical equipment such as automobiles, information devices, electrical machines, heavy industry/plants, and production equipment, but their use and scope of application also extends to a wide range of industries, including civil engineering and building structures. They help to reduce maintenance, conserve energy, and prevent environmental pollution.
The friction, wear, and lubrication fields of technology are jointly referred to as "tribology." Oiles Corporation Group is constantly introducing new products into the market and increasing our market competitiveness by mastering the tribology and damping (vibration control) categories. We are making every effort to ensure stable profits in any environment and to increase our ongoing business valuation by restructuring the management of the entire group and improving the quality of our management.
Associated with bearings in a broad sense, every machine is designed to run smoothly without a hitch. The bearings are largely divided into roller bearings and plain bearings.
Normal plain bearings tend to seize because of a high load, movement form, mixture of foreign matters, temperature condition, improper lubrication and maintenance, and so on.
Even in the condition where these normal plain bearings are not suitable, OILES bearings exhibit the performance requested for the bearings, such as wear resistance and seizure resistance, to materialize performance enhancement and maintenance-free devices.
Oiles bearings are environmentally friendly plain bearings that require either no lubrication, or a reduced frequency and amount of lubrication. They are widely used in various industrial machines, including automobiles.
