边缘润滑bushing

Structure: 1.POM 0.30 0.50mm, has high wear resistance and low friction even only minute quantities of lubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing. 2.Sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the resin mixture. 3.Low-carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation. 4.Copper plating 0.002mm, good corrosion resistance. Features: Suitable for rotary and oscillating movement, lower maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads. Applications: Recommended for applications involving intermittent operation or boundary lubrication... Automotive: suspension joints, kingpin assemblies and stub axles of tucks, automobile driving joint hinges, steering and other linkages, articulation joints, rear chassis hinges, fairleader rollers... Machine tool building industry: spindles in drill, grinding, and milling machines, ram guide plates in multiram presses... Agricultural equipment: gearbox, clutch, bale trips and wheel caster swivels for bale accumulators, front axle pivot bearings, steering idler box bearings and kingpin bearings for harvesters... Be especially well-suited for applications where lubricant can not be supplied continuously or repeatedly.
