Basic knowledge of Slidie Bushing Bearing

  Slide bushing bearing is a ring structure component with sealing and wear protection functions. It is mainly used in mechanical fields such as valves and bearings. It achieves sealing function by wrapping the valve stem or reducing the clearance between the shaft seat. It uses corrosion-resistant materials such as polytetrafluoroethylene and graphite to reduce equipment maintenance costs. During processing, it is necessary to control the precision of the cone angle difference and wall thickness difference of the tightening sleeve.
  This component can reduce mechanical vibration, noise, and corrosion, and the selection should be based on pressure, speed, and lubrication conditions. During installation, it is required to cross tighten the bolts and perform regular rust prevention treatment. The thread locking function must comply with the general thread standard to achieve bearing fastening. The flexibility of using slide bushing bearing is relatively high. It can also have many effects. Generally speaking, bushings are a type of component used to protect equipment. The use of bushings can reduce equipment wear, vibration, and noise. And it has anti-corrosion effect. The use of bushings can also facilitate the maintenance of mechanical equipment, simplify the structure and manufacturing process of the equipment.

  The role of the liner in practical work is closely related to its application environment and purpose. In the field of valve applications, a liner is installed inside the valve cover to cover the valve stem, thereby reducing valve leakage and achieving a sealing effect. In the field of bearing applications, the use of bushings can reduce wear between the bearing and the shaft seat, and avoid increasing the gap between the shaft and the hole.

The materials of bushings are mostly soft metals, rubber, nylon, and non-metallic polymers, which are relatively soft in texture and have lower prices and costs. In various harsh working environments, the lining is subjected to vibration, friction, and corrosion to protect the wrapped components, and the lining itself is easy to replace, low-cost, and cost-effective after damage.
Factors influencing the selection of lining materials
The use range of bushings is wide and there are many types. To choose a suitable bushing, it is necessary to consider its purpose of use and choose different types of bushings for different working conditions. The main considerations in selecting a liner are the pressure, velocity, pressure velocity product, and load properties that the liner needs to withstand. In addition, whether the liner is lubricated and the lubrication status also determines its effectiveness and lifespan.
