Product description

The ready-to-install plain bearings in either combined steel, bronze and plastic or sintered bronze are self-lubricating and maintenance-free. They are used in dry-running and lubricated applications in diverse sectors of electrical equipment, mechanical engineering and construction. The plain bearings exhibit high chemical resistance and comply with the European RoHS guidelines. At norelem, they are available directly ex warehouse in bushes and collar bushings with an internal diameter of 3 - 50 mm and in thrust washers. The rolled composite plain bearings made of steel and sintered bronze are particularly suitable for dry-running conditions. With a copper-tin base, the carrier plate is protected from corrosion and inside, the sintered bronze in combination with a PTFE and lubricant coating ensure smooth rotation. This combination of materials ensures optimum and virtually wear-free sliding with the highest load and conductive capacities. It prevents the flow of additive materials even with high bearing loads. Composite plain bearings are also suitable for lubricated applications as well as for rotational and oscillation movements. The plain bearings have no stick-slip effect and absorb practically no water. Plain bearings made of sintered bronze are oil-soaked and self-lubricating: Oil is transferred to the rotating shaft from the absorptive capillary system, which is then absorbed from the plain bearing when the shaft is stationary. Additional lubrication is not required under normal operating conditions. Due to their ability to store oil, sintered bronze plain bearings are suitable for devices in continuous operation such as electrical motors, ventilators and household appliances. It is simple to assemble the cost-effective plain bearings using a suitable mandrel.
