Metal-Polymer Plain Bearings Oil/Grease Lubricated Bushing With Blue POM Coated Self Lubricating Bearing
Metal-Polymer Composite Plain Bearings| VIIPLUS Self-lubricating Bearings
Metal-polymer composite plain bearings are bearings for very small radial or axial pouches. They work with little noise and are particularly suitable where high loads must be supported in combination with a relatively slow rotation and rotation movement. These products are available as bushings, flanged bushings and thrust washers in two groups of materials.
Metal-Polymer Plain Bearings Grease Lubricated
POM bearings are made with a steel support on which a sintered bronze layer is applied. An upper POM layer is then applied to this bronze layer. The intermediate bronze layer ensures effective heat dissipation and creates a strong union between the steel support and the sliding surface.
The steel primer is provided with a layer of copper or tin to prevent corrosion, while the top POM layer contains grease wells to retain grease.
·Quiet operation free of squeaking or knocking.
·Damage prevention to shaft.
·Virtually wear-free bearing surface with minimal lubricant.
·Low friction for smooth rotation at startup and at low speed under high load conditions.
·Seizure-free sliding surfaces.
·Excellent shaft misalignment tolerance.
·Ability to withstand impact loads.
·Excellent load-carrying performance even under oscillating and fretting conditions.
·Metal-Polymer Plain Bearings for grease or oil lubricated applications
·Standard parts contain recesses in the sliding layer; smooth sliding layer available on request
·Optimal performance at relatively high loads and low speeds
·Suitable for linear, oscillating and rotational movements
·A wide range of parts available from stock
STRUCTURE AND COMPOSITION
Metal-Polymer Composite Bushing Material
Steel Back + Porous Bronze Sinter +
POM with Lubrication Indents
1. Self-lubricating. POM layer 0.3-0.5 mm. Once the lamination process is complete, the POMs are filled in the intersection of the bronze layer, the lubrication marks are printed, which are full of oil grease, which will be removed and transferred to the mating surface, form a lubricating film physically, which will reduce the fire. and protect the coupling shaft.
2. Porous bronze layer; The layer provides self-lubricating strength. Layer.
3. Steel support The layer provides load and thermal conductivity
4. Copper / tin layer.

Main advantages of POM bearings include:
·High sliding velocity
·High load capacity
·Low friction coefficient
·Minimal bearing play
|Process fluid lubricated
Metal-Polymer Plain Bearings are particularly suitable for harsh environments where frequent maintenance is not possible.
