Steel base inlaid graphite bearings are specifically designed for high-temperature applications in winder and crane support systems. These bearings incorporate graphite inserts within a steel base, providing exceptional wear resistance and lubrication properties in demanding environments.
Graphite, known for its low coefficient of friction and high thermal stability, serves as the primary lubricating material within the bearing. This natural lubricant effectively reduces friction and wear, ensuring smooth and reliable operation of the winder or crane support system.
The steel base of these bearings offers excellent strength and durability, making them suitable for applications involving heavy loads and high temperatures. The steel construction ensures that the bearings can withstand the rigors of continuous operation and maintain their integrity over extended periods.
In winder and crane support systems, where precise alignment and stability are crucial, steel base inlaid graphite bearings offer a superior solution. They provide the necessary support and stability, while also ensuring smooth and reliable motion of the equipment.
The high-temperature resistance of these bearings makes them ideal for applications involving extreme operating conditions. Whether it's a winder operating in a hot environment or a crane supporting heavy loads in a demanding industrial setting, steel base inlaid graphite bearings can handle the challenge.
In summary, steel base inlaid graphite bearings are an excellent choice for high-temperature applications in winder and crane support systems. Their combination of graphite's lubricating properties and steel's strength and durability ensures smooth and reliable operation in demanding environments.
Steel Base Inlaid Graphite Bearings is made of Iron GCr15 material. It has high compressive strength and is especially suitable for supporting at low, medium and high loads. It outperforms other 500 models due to its excellent high hardness under high loads. Not suitable for water, acid, alkali. Most suitable for supporting the hoisting machine, such as bulldozer support, hoist support, winder support, etc.
Steel base inlaid bearing, is a reinforced product, has a higher compressive performance, in the work can discharge lubrication particles, so that a layer of diaphragm between the shaft and sleeve, played a more than monomer oil lubrication anti-bite advantage, especially suitable for the support parts of lifting machinery.

1. Bronze alloy bearings with graphite plugs provide both good wear
resistance and excellent self-lubricating properties to this
bearing.
2. This marking enables the bearings to run without lubrication or
maintenance.
It is widely used in the field of high load and intermittent motion
as well as oscillating motion conditions.
4. Steel Base Inlaid Graphite Bearings is widely used in automobile
assembly line, water turbine, gate damper, plastic injection
machines, etc.
Steel base inlaid bearing, is a reinforced product, with high compressive performance, when working can discharge lubrication particles, so that a layer of diaphragm between the shaft and the sleeve, has the advantage of more anti-bite than monomer oil lubrication, in the support of lifting machinery is particularly suitable.Suitable for the support of winder and crane, but not suitable for use in water or acid and alkali.

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 is required.With the increasing of cost requirement, the reliability of equipment and plant operation is becoming more and more demanding.
Metal self - lubricating bearings are maintenance-free and self - lubricating under long - term service conditions, making it possible to design reliable long - term self - lubricating systems.Metal type self-lubricating bearing materials can be widely used in high load and low speed conditions of rotation, swing and linear reciprocating movement, but also suitable for traditional lubrication can not be reached or is prohibited from use, or in special conditions such as dust, impact load or radiation conditions need long-term and stable use.
1.Use standard specifications when possible;
2.Please pay attention to the presence of foreign bodies on the surface during assembly.
3.After using the sliding surface, the surface is black or gray-black due to the oil film formed by the solid lubricant. Please do not scrub and use as usual.
4.Before assembly, if the lubricating oil is applied to the grinding parts, the short running period can be reduced, which is conducive to the mechanical operation and operation.
5.When assembling, press in slowly, and do not knock, so as to avoid damaging the bearing and causing deformation.
6.When designing, different parts should be made of appropriate materials, so as to improve the mechanical properties and prolong the service life of the bearings.
7.In high load and reciprocating motion, screw fixation is recommended.
8.Stainless steel or chrome plating is recommended for grinding shafts in fresh water, sea water and at sea.
