Self-Lubricating Sliding Bearings

Bearings are used as a mechanical component to transfer the power and to move a certain part, and this is done by utilizing the small frictional force of the bearings, which makes them rotate easily. Bearing products can be further divided into various types according to different classification methods. When depending on friction type, they can be classified into two major groups, namely, sliding bearings and rolling bearings.

Sliding bearing can represent both the hydrodynamic lubrication bearings requiring lubricants that automatically form the oil film in the space between shaft A and bearing B by way of rotating the shaft and the hydrostatic lubrication bearings requiring lubricants that elevates the rotating shaft by providing the pressurized lubricant from outside.

Besides, they can also represent both the self-lubricating bearings made of special material that requires no lubricants between shaft A and bearing B and the ones made of porous material to be soaked with lubricants. Now let us talk something about the self-lubricating sliding bearings.

With the development of the technology, there are more and more requirements for the performance of the bearings. Even zero maintenance is expected under severe to extreme conditions as well as under maximum loads. The constant pressure on costs additionally calls for increasing uptime of machinery and equipment and uncompromising standards of operational reliability.

Maintenance-free, self-lubricating, heavy duty friction materials produced for bearings of the automotive industry offers bearing solutions guaranteed to operate reliably and safely over long term. Therefore, the self-lubricating sliding bearings are manufactured to meet special requirements.

Self-lubricating composite sliding material manufactured by using a continuous hot rolling sintering technology which increases the reliability and service lifetime of the sliding plates significantly. It is characterized by high wear resistance, insensitive to impact stress and resistant to harsh operational and ambient conditions of mechanical and chemical environment.

It normally requires no lubrication and allows maintenance free. It is suitable for rotational, oscillating and linear movements. These materials can be machined to complex geometrical shapes without the loss of the self-lubricating properties. In addition, they possess a high static and dynamic load bearing capacity. These bearing materials contribute to enhance performance and optimum characteristics in all industrial segments. The dry wear mechanism enables these bearings to operate satisfactorily in the absence of conventional lubricants.
