Smooth running plain bearings
04 March 2021
NORELEM'S RANGE of plain bearings help ensure devices run smoothly and efficiently for engineers, due to their ability to store oil. the range includes composite plain bearings and rolled composite plain bearings, designed to be used in dry-running and lubricated applications, as they are self-lubricating and maintenance-free.
The ready-to-install plain bearings range is available in either combined steel, bronze and plastic or sintered bronze. norelem’s sintered bronze plain bearings are suitable for devices in continuous operation such as electrical motors, ventilators and household appliances.
Sintered plain bearings are also 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.
norelem’s composite plain bearings are suitable for lubricated applications as well as applications that require rotational and oscillatory movements. The plain bearings range has a no stick-slip effect and absorbs no water, enabling free movement and precision during operation.
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.
The plain bearings exhibit high chemical resistance and comply with the European RoHS guidelines. norelem’s range is available in bushes and collar bushings with an internal diameter of 3-50 mm and in thrust washers.
