DX bushing
MP20 is a typical marginally-lubricated bearing material,which is based on steel backing,and porous bronze powder are sintered onto the steel backing,POM mixture are evenly coated onto the bronze sinter layer.
| MP-20 Structure | Features |
| Steel bronze powder with POM marginal bearings1.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. | 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. |
| Typical Application | |
| 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. |
