    The nine advantages of oil-free self-lubricating bearings

    Self-lubricating bearing is developed on the metal friction surface of the bearing matrix with holes arranged in order and appropriate size, and embedded in molybdenum disulfide, graphite and other composite self-lubricating block embedded in the metal sleeve, the composite bearing made of solid lubricant friction area up to 25-65%.The solid self - lubricating block can work normally at 280℃.But because of its low mechanical strength, bearing self-lubricating bearing capacity is weak, easy to produce deformation, it can be embedded in the metal hole groove to suppress this defect, the formation of metal part bearing function, self-lubricating block lubrication function.The lubrication mechanism of the self-lubricating bearing is that during the sliding friction process between the shaft and the sleeve, part of the molecular oil-free bearing of the self-lubricating material is transferred to the metal surface of the shaft to fill in the tiny non-plane and form a stable solid lubrication film, which causes the friction between the solid lubrication film and prevents the adhesive wear of the shaft and the sleeve.This rational combination combines the complementary advantages of copper alloy and non-metallic anti-wear materials, which is especially suitable for non-oil, high temperature, high load, low speed, anti-fouling, anti-corrosion, and strong radiation environment, as well as for special working conditions in which lubricating grease cannot be added to water or other solutions.

    The area ratio of self-lubricating block to the surface area of self-lubricating block is related to the running speed and pressure strength, and the running speed is low.Pressure strength, metal area should be larger.

    The advantages of oil-free self-lubricating bearings are as follows:

    1. Oil-free or oil-less lubricated bearings are suitable for places where oil cannot be filled or it is difficult to fill. They can be used without or with little maintenance.

    2. Good wear resistance, small friction coefficient and long service life.

    3. There is an appropriate amount of elastoplasticity, which can distribute the stress on a wider contact surface and improve the bearing capacity.

    4. The coefficient of static and dynamic friction is similar, which can eliminate the creep at low speed, thus ensuring the working accuracy of the machine.

    5. It can reduce vibration, reduce noise, prevent pollution and improve working conditions.

    6. Transfer film can be formed in the operation process to protect the grinding shaft, without biting the shaft.

    7. The hardness requirements for the grinding shaft are low, which can be used without adjusting the shaft, thus reducing the processing difficulty of related parts.

    8. Thin wall structure, light weight, can reduce the mechanical volume.

    9. The bushing is made of brass and can be used in corrosive media.

  • FLANGE BUSH

    Solid Mosaic bearing series is the general basic products, regardless of high pressure, low pressure, high temperature, low temperature, oil lubrication, no oil lubrication or water lubrication, can adapt.The matrix of the product is high strength brass, than the general copper set hardness increased by one time, wear resistance increased by more than one time.

    Widely used in: light industry machinery, heavy industry machinery, construction machinery, metallurgical machinery, transport machinery, such as: continuous casting machine, rolling mill, injection molding machine, paper machine, mold guide column, ships, machine tools and so on.
