- Suitable for high load capacity, very good at low sliding speeds, good chemical resistance, long life-span, good damping features.
Fibre reinforced plastic composite sliding bearing
With the COM-KU®/D, we offers you a self-lubricating and maintenance-free plastic sliding bearing, which brings together the greatest advantages of this material: good sliding qualities, chemical resistance and a long service life. This means that it is suited to a range of applications – from machinery, equipment and drive construction to construction and agricultural machinery, shipbuilding and use in off-shore facilities. Read here about the success of this product.
Our plastic sliding bearing COM-KU®/D is manufactured from fibre-reinforced compound plastic using winding technology. Its material characteristics are summarised below:
The sliding bearing is suited for a temperature range between -150ºC and +130ºC and has very good sliding characteristics at low sliding speeds. It resists high to very high loads, including impact loads and edge pressing. It also has good attenuation properties, which has a positive effect on its resistance to impacts.
For a shaft material in COM-KU®/D, steel should be used with a Brinell hardness of more than 200 HB and a roughness depth of less than 6.3 Rz. The tolerance of the shaft varies according to the application, that of the bushing after installation according to its diameter. Please note as a matter of principle that installation dimensions and tolerances should be designed to be “plastic suitable” for plastic sliding bearings. Above all, an enhanced expansion coefficient should be taken into account relative to metal sliding bearings, from which larger tolerance ranges and bearing clearance fits can result. After installation, the COM-KU®/D plastic sliding bearing operates completely maintenance-free. Replacement is easily possible even with lubricated bearings. This means that our product not only saves on costs, but also guarantees operation without any impairment in its area of application. If you have further questions on plastic sliding bearings and other products, we look forward to your message via our contact form or your call!
*) Only the bushing with its wear-resistant material is maintenance-free. Please consider the parts surrounding the bushing, such as housing and shaft, whether they may require anti-corrosion lubrication!
On request further materials are available for higher demands, e.g. for higher temperature ranges.
The above stated material properties are valid for optimal operating conditions. Through changes of the application conditions e.g. higher sliding speed or strain, these values are subject to change.
