Flange Collar Bronze Plugged Bearings, Self-Lubricating Bearing Metric Size refer to bearings that have a flange collar design and are made of bronze material. These bearings are often plugged or filled with a lubricating compound to provide self-lubrication properties. They are available in metric sizes, which means their dimensions are specified in metric units like millimeters (mm).
These bearings are commonly used in applications where lubrication may be difficult or impractical, as the self-lubricating compound can help reduce friction and wear over the bearing's lifetime. The flange collar design adds strength and rigidity to the bearing, allowing it to handle higher loads and moments.
The bronze material used in these bearings offers good corrosion resistance, strength, and durability, making them suitable for a wide range of applications in industries like machinery, automotive, and aerospace.
Bronze Plugged Bearings are customer-specified products. Its base is CuSn10P1 material which is lead-free and is widely used in powder
metallurgy products. It has relatively low coefficient of friction but also relatively low load
bearing capacity. After graphite impregnation, it can be used without oil
lubrication.Compared with regular bronze bearings, Bronze Plugged
Bearings has much better elasticity and wear-resistance properties,
is mainly used in low load, high temperature, and moderate speed applications.

The sobf- maintenance-free plain bearings are made of very hard bronze (base material) and specially arranged 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.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.
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.
