Maintenance free-self lubricating sliding elements solid lubricant, Flange Bushing, Cast Bronze Bearings.

Mainly Mat. ZCuZn25AI6Fe3Mn3, DIN1709/G-CuZn25AI5, CAC304, C8630, SAE 430B, HTB2,500#SP

Self lubricating flange bearings in extra durable bronze:  To embed the solid lubricant, we recommend the following minimum wall thickness:

  • Wear plates: > 5 mm
  • Bushings: 5 % of ID + 3 mm

Lubrication Bronze Bearing Parts

Graphite with additives is used as lubricant.

After grinding in the die, the die is cleaned. When the sliding elements are dry they should be treated with the “correct” oil to prevent the elements from dry running until the working temperature is reached.

Important: Graphite alone doesn’t have enough lubrication function. The proportion of lubrication on the

sliding surface is 25% – 35%.

    Modern design is creating a huge demand for today’s self-lubricating bearing materials. Even in severe extreme operating conditions and maximum load conditions maintenance free is required. With the continuous increase of cost requirements, enterprises have higher and higher requirements on the reliability of equipment and plant operation. Metal self – lubricating bearings can meet the requirements of maintenance – free and self – lubricating in long – term service conditions, which makes it possible to design a reliable long – term self – lubricating system. Metal type self-lubricating bearing materials can be widely used for rotating, swinging and linear reciprocating motion under high load and low speed conditions, and also suitable for occasions where traditional lubrication cannot be achieved or is prohibited, or for long-term and stable use under special conditions such as dust, impact load or irradiation.

    Our products are used in many industries.
