Application of JDB in Oilless Bearing
JDB has a strong wear resistance, JDB has high strength, hardness, chemical resistance and
strong. As well as cutting machine performance is also very good. JDB often made of sheet metal,
bar, pipe, casting parts and so on.
JDB is widely used, made by casting into the bearing and bushings, the domestic now mainly use
JDB for production of solid lubricating oilless bearings (solid bearing), is the use of high-
strength brass (Usually graphite, molybdenum disulfide, polytetrafluoroethylene, oil an other
lubricants), the superiority of its mainly in the copper alloy and non-ferrous metal grinding
materials have their own complementary advantages, both with a high carrying capacity, but also
break through the general bearing oil film grease lubrication through the boundaries of oil-free
lubrication, embedded solid lubricants easy to form a lubricating film, its friction and wear
properties to a great improvement in the role of stable and reliable high cost. Compared with the
composite oil-free bearings, it has a good workability, high precision, strong carrying capacity,
good wear resistance advantages. This self-lubricating guide can be used in many areas, such as
:ergineering machinery joints excavators, mine scraper, rotary drilling rig, concrete pump
truck, rock drilling machinery, hoist, port crane. Mechanical casting machinery, water machinery,
transportation machinery, rolling mill, blow molding machine blown film machinem injection
molding machine cross head mold differential, tire curing machine, trailer balance beam, vacuum
switch.
