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.
