According to the reports,in order to settle the troubles such as high temperature,low speed,heavy load,heave dust and shock vibration in the operation of machines,we usually use the oil-free self-lubricating bearings.Oil-free self-lubricating bearings could not only be used on aluminium ingot casting machines perfectly but also could be used on the oil-free,high temperature,heavy load,low speed,dust protection,corrosion protection and strong radiation environment.What's more,it could be used on the machines which work under the water.
Although nowadays most of the bearings used on various machines are ball and needle roller,only small part are oil-free self-lubricating bearings. We believe that the powder metallurgy oil-free self-lubricating bearings would become the leading power in near future.
