SF-22 oil free lubrication bearing is an improved product used steel back as base, agglomerated
by globular tin bronze powder in the middle and rolled by acetal resin and polymer material
containing oleophylicity ber and special lubricant. It is the same to external DS bearing and
applicable for the situation of dry friction and little oil lubrication at ordinary temperature,
characterized by low friction factor, well wearing performance and oil free condition lubrication.
At present, the product has been used in swaying motion, situation easy to wear and erode, such
as winding engines, dozers, printing and dyeing machines, coal-cutters, winch truck, traveling
crane and so on.
