The Bronze Thrust Bearing 954 Bronze with Graphite Plugs is a
highly specialized component designed to provide superior wear
resistance and durability in thrust bearing applications. The
combination of 954 bronze and graphite plugs offers a unique blend
of properties that ensure smooth and reliable operation.
The 954 bronze, often referred to as tin-based bronze, is chosen
for its excellent strength, corrosion resistance, and thermal
conductivity. This material is well-suited for demanding
applications that require a bearing material that can withstand
high loads and temperatures.
The graphite plugs, evenly distributed within the bronze matrix,
provide a continuous source of lubrication. Graphite is a natural
lubricant that reduces friction and wear, ensuring smooth operation
of the thrust bearing. The plugs act as reservoirs of graphite
lubricant, releasing it as needed to maintain the desired level of
lubrication.
The incorporation of graphite plugs into the 954 bronze matrix
results in a thrust bearing that is both strong and
self-lubricating. This eliminates the need for external
lubrication, reducing maintenance requirements and downtime. The
self-lubricating properties also ensure consistent performance and
longer bearing life.
The Bronze Thrust Bearing 954 Bronze with Graphite Plugs is
suitable for a wide range of industrial applications, including
heavy machinery, presses, punches, and other equipment that
involves thrust loads. It is particularly well-suited for
applications where lubrication may be difficult or undesirable due
to dust, dirt, or other contaminants.
In summary, the Bronze Thrust Bearing 954 Bronze with Graphite
Plugs offers superior wear resistance, durability, and
self-lubricating properties. It is an excellent choice for thrust
bearing applications that require a reliable and long-lasting
bearing solution.

PODKŁADKA ŚLIZGOWA SOBW , SOBW- maintenance-free - sliding washer is made of very hard bronze (base material) and
specially placed solid grease (graphite).
Set the graphite to match the direction of travel.
The base material bears the load, and the solid grease ensures the
lubrication of the bearing throughout its service life.
The graphite composition must be able to lubricate the sliding
surface of bronze.As the bearing rotates, the grease film diffuses
to brown.
This means that there is always a gap between the two sliding
surfaces in order for the bronze and graphite to work effectively.
Recommended maximum operating temperature: 300°C (bearing manufactured at 1000°C) greater clearance shall be
provided to compensate for thermal expansion at operating
temperatures above 100°C.

Bronze Thrust Bearing enhance the hardness of high hardness brass, giving rise to higher
load bearing capacity and better wear-resistant property. The
products are widely used in continuous casting rolling machine,
mining equipment, engineering equipment, injection-molding
machines, etc. Because of its high hardness, it's difficult to
machining and finish, it's recommended only for really high load
applications.
Basic material | CuZn25A16Fe3Mn3 | Dynanic load | 120N/mm² |
Base hardness | HB210~275 | Friction Coef | <0.16 |
Temperature Max | 300℃ | Speed limit | dry 0.4m/s oil 5m/s |
Necessary maintenance usually involves checking consumption every
six months to two years, depending on usage time and load.It is
recommended that the parts be re-lubricated each time they are
removed.Do not remove the existing solid grease layer.Continuous
lubrication is not required, as the part does not require
maintenance if all requirements for the use of bronze with solid
grease are complied with.Machining: bronze is easy to process.
Basically, there is not much difference between our products and
ordinary steel processing.No special tools are required, but
remember to use sharp tools, preferably new ones.
It is recommended to use the grease for HSS or carbide tools.As
with ordinary steel, the distance of the machine is about 0.3 mm
during rough milling.When milling/roughing, use low feed rate and
low cutting depth.Operating temperature: -50°C / + 200°C (Max.
300°C)
Application characteristics
Jdb-1 is a universal basic product, regardless of high pressure,
low pressure, high temperature, low temperature, oil lubrication,
oil free lubrication or water lubrication.They all apply.
The matrix of the product is high-strength brass, which is twice as
hard as the general copper cover.Wear resistance increased more
than twice.
Therefore, the continuous casting machine, rolling mill, conveyor
in the metallurgical industry can be used.Also used for plastic
injection molding machine locking mechanism, extrusion
mechanism.Automatic switch of high voltage, lifting support of
construction machinery, and arc door support of water conservancy
project.Pulley and drive wheel parts.There are also paper dryer,
automobile mold, ship anchor sliding parts and so on.
JDB 1 2 is mainly suitable for low load, high temperature and medium speed applications, such as fireplace door hinges, oven raceway, light industrial
machinery, machine tool industry, etc.
The internal material of jdb-3 is the same as that of jdb-2. In
addition to the function of jdb-2, it also reflects the functions
of saving cost, improving compressive strength and welding and
installation of end face and matrix.
It is suitable for non-oil lubricating parts in construction
machinery, metallurgical machinery and conveying machinery.
Jdb-4 is a typical material - saving product where mechanical
properties are not required.It can be used as a substitute material
for jdb-2.Can greatly reduce the cost, to meet the use of
requirements, such as: mold guide sleeve, injection molding machine
mold frame.
Jdb-5 is an enhanced product.It has very high compressive
performance, especially suitable for supporting parts of the crane,
such as excavator support, winch support, crane support, etc.But
because the matrix is steel.So should not be used in water or acid,
alkali occasion.
