The bushing is a fitting for the purpose of sealing and wear protection, etc., and refers to a ring sleeve functioning as a cushion. In the field of valve applications, the bushing is inside the bonnet, and a corrosion-resistant material such as polytetrafluoroethylene or graphite is generally used for sealing.
Characteristics of steel sleeve bearing
IKO micro-miniature linear bushing bearings are extremely small linear motion guides that rotate side and axis, infinite linear motion in the direction of the axis of the contact, and the shaft diameter is 3~5mm. Features are:
1. Low frictional resistance: The steel ball can be stably linearly moved with a very small frictional impedance due to the correct orientation of the retainer.
2, stainless steel: also provides stainless steel series, suitable for corrosion resistance needs.
3, exquisite design: very small size, can be designed in delicate mechanical equipment.
4, rich changes: In addition to the standard type, there is a series of high-rigidity long, can be selected according to the purpose.
Basic concept of steel sleeve bearing
The role of the bushing
Bushings have a high degree of flexibility in use, and they can do a lot of work. In general, bushings are a type of component that protects equipment. The use of bushings reduces equipment wear, vibration and noise and provides corrosion protection. The use of bushings also facilitates the maintenance of mechanical equipment, simplifies the structure and manufacturing process of the equipment.
The role of the bushing in actual work has a lot to do with its application environment and purpose. In the field of valve applications, the bushing is placed inside the valve cover to cover the valve stem to reduce leakage of the valve and achieve sealing. In the field of bearing applications, the use of bushings reduces wear between the bearing and the shaft seat, avoiding the increase in clearance between the shaft and the hole.
Bushing selection factor of steel sleeve bearing
Bushings have a wide range of applications and a wide variety of types. To choose a suitable bushing, it is necessary to consider its purpose of use. Different types of bushings are selected for different working conditions. The main considerations in bushing selection are the pressure, speed, pressure velocity product and load properties that the bushing is subject to. In addition, whether the bushing is lubricated or lubricated also determines its use effect and life.
