CUZN25AI5MN4FE3 is a type of graphite cast bronze alloy bearing
material that is commonly used for applications such as loading
machines and excavators. This alloy is known for its excellent wear
resistance, strength, and ability to withstand heavy loads and
impacts.
When it comes to "PLUG GRAPHITE CAST BRONZE BEARINGS FOR LOADING
MACHINE & EXCAVATOR," these are specifically designed bearings that
are cast from the CUZN25AI5MN4FE3 alloy and then machined or formed
into the appropriate shape and size to fit into the loading machine
or excavator. The graphite in the alloy acts as a natural
lubricant, reducing friction and wear on the bearing surface.
The term "SOLID SLEEVE BUSHING" refers to a type of bearing design
where the bearing is a solid sleeve or cylinder that fits into a
housing or other structure. This design provides support and
guidance for rotating or sliding parts while also reducing friction
and wear.
In summary, CUZN25AI5MN4FE3 graphite cast bronze bearings are a
durable and reliable option for loading machines and excavators,
providing excellent wear resistance and the ability to withstand
heavy loads. The solid sleeve bushing design further enhances the
bearing's performance by providing a stable and reliable support
structure.

For all the global industry
Provide high-quality self-lubricating products
Application Notes
1. Use standard designation when designing if possible;
2. Note if there are any foreign matters on the surface when
assembling;
3. Do not erase the black or grey phenomenon on the sliding surface
caused by the oil film that is formed by the solid lubricant after
using;
4. It is good for mechanical operation and running if lay the
lubricant on the corresponding friction set before installing;

What are the advantages of using solid lubricating bearings?
Solid lubrication refers to the use of solid powder, film or the
whole material to reduce friction or reduce wear lubrication. Then this method used in the bearing effect above is also very
good. Solid lubrication is better than oil lubricated chemical
stability, it can make the bearing lubrication system simple,
without causing pollution to other adjacent parts of the problem,
so the applicability is very good. So it is suitable for oil-free, high temperature, high load, low speed environment, while the solid lubricating bearings are increasingly widely used
in other industrial and agricultural machinery. So it is very
flexible to use, at the same time can be for a variety of special
occasions, the solid lubricating bearings designed into various
shapes to meet the needs of various occasions.
Material
CuZn25AI5Mn4Fe3
Structure Characteristics and Applications
VSB-50 Solid Lubricating Bearing is produced by strengthening brass
that has good physical performance and good capability for casting. What's more, the brass material has pretty good anti-erosion
abitity in air, fresh water and sea water. The surface is regularly
and finely machined with sockets in which particular solid
lubricant is filled. The product is widely used on consecutive
casting and rolling machines, mine-exploiting equipments, ships,
steam engine, etc.

Characteristics
with Solid Graphite Lubrication. Various material specifications,
standard and special shapes are also available
VSB-50 Solid lubricating bearings
1. May work without any ol for long period
2. Extremely high load capacity, good anti-wear and lower friction
3. Particularly appropriate for low speed and high load
4. Suitable for reciprocating, oscillation or intermittent motion
where oil film is hard to be formed
5. Good chemical resistant and anti-corrosion characteristics
6. Can b€ used in wide range of temperature from -40℃-+300℃
Strusture
VSB-50 SOLID LUBRICANT SLIDING BEARINGS material is made of strong
cast bronze based metal with special solid lubricants embedded. The
base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low
temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.
