| Message: | Self-lubricating ball bearing DX bushing braking system bushingHigh wear resistance and low friction even only minute quantities of lubricant are supplied,Website:http://www.oilite-bearing.com, the bearing surface carries a pattern of circular indents which should be filled with grease on assembly. Now this materials have been widely used in metallurgy machines, mine machines, water conservancy industries, automotive, agriculture manchines, rolling mill etc which for rotary and oscillating movement.1. PTFE/Fiber mixture thickness 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxidetype solid lubricant film.2. Sintered bronze powder thickness 0.20-0.35mm,provides Max. thermal conductivity away from the bearing surface also serves as a reservoir for the PTFE-Fibremixture.3. Low-carbon steel gives exceptionally high load carrying capacity, excellent heat dissipation.4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.Max.LoadStatic250N/mm2 Friction coefficient0.03~0.20Very low speed140N/mm2Rotating oscillating60N/mm2Max.
