Oil Sintered Iron Bushing DU-F flanged bushing Manufacturer from bearingtypes's blog

Marginal lubricating bushing on the requirements of grinding parts Solid self-lubricating bearings are mainly JDB-1, SF-1, FB09G, and other series of bearings, in the initial stage of the work gradually through the wear and tear self-lubricating material gradually transferred to the grinding surface of the workpiece surface formed in the hard lubricating film; Its friction and wear properties mainly rely on the performance of solid lubricants, self-lubricating bearings face material is usually copper alloy, aluminum alloy - bimetal, babbitt, PTFE, modified polyoxymethylene, rubber, Molybdenum disulfide, black lead and the like. Which can form a solid lubricating film on the surface of the solid self-lubricating bearing to separate the moving sub-surface, the sliding frictional force can be greatly reduced, and the wear of the shaft can be avoided. Solid self-lubricating bearings and shaft sliding friction occurs,Filled and Modified Fluoroplastic Series and the shaft in the process of running to transmit torque and movement, so the hardness of the shaft material and strength requirements are higher, JDB-1 self-lubricating bearings commonly used metal to wear parts, hardness HRC40 °;DU-F flanged bushing SF-1 bushing is lower, the use of the general 45 # steel can also be. For the friction and wear properties of solid lubricants mainly rely on the performance of solid self-lubricating bearing bearing capacity, high precision rotary, solid lubricating film with impact resistance. The solid lubricating film is solid self-lubricating bearing surface material itself has good self-lubricating properties, in the initial stage of the work gradually through the wear and tear self-lubricating material gradually transferred to the grinding surface of the workpiece surface formed in the hard lubricating film; This is the roughness of the grinding surface of the workpiece have certain requirements, the general requirements of Ra0.4 ~ 1.6 between; too smooth or too rough surface is not conducive to the transfer of lubricant to the work surface hindered the completion of the lubrication film; Solid lubricating bearings are generally required to be grinding the surface to the polished surface; when the solid lubricant film is fully formed, the movement between the shaft and the bearing has actually changed into a friction between the lubricating film and the bearing movement,Oil Sintered Iron Bushing is not directly practical In contact with the bearing surface.
