Product Detail

In the moving parts, because of the long-term friction caused the wear of parts, and the axial clearance hole wear to a certain extent must replace parts, so the designers choose low hardness material with better wear resistance for the sleeve and bushing at design time, it can reduce the wear of the shaft and the shaft sleeve, or when bushing wear to a certain degree to change, so you can save the cost by replacing the shaft or the seat, in general, the Bush and the seat by interference fit, and axis of the clearance fit, because no matter how cannot avoid wear, can prolong the life of shaft parts, and relatively easy to process; there are also some new the designer does not love this design, that is to increase the cost at the time of manufacture, but after a period of time after use, maintenance or according to this party Method of transformation, but the transformation is likely to cause lower accuracy of the equipment, the reason is very simple, two processing can not be guaranteed some of the center of the seat hole position of the sleeve, in some low speed, radial load and high clearance for better place (such as camshaft) to replace the bearing sleeve (in fact, is also a kind of sliding bearing material requirements), low hardness and abrasion resistance, sleeve bore through grinding and scraping, can achieve high matching precision of oil tank must have a lubricating oil on the inner wall of the sleeve, the lubrication is very important, dry grinding, shaft and shaft sleeve will soon be scrapped, here recommended installation scraping hole wall sleeve so, can leave many small pits, enhance lubrication bushing and bushing is selected according to different types of different mining conditions. The most important conditions are pressure, velocity, pressure and velocity product, lubrication state, and load properties. The quick and easy selection of the bushing is included. 
Wrapped in the stem, it is worn out and can be easily replaced. If the bushing is not used, after wear, the replacement is the part. So the replacement is to replace the bushing (when the design is designed, the hardness of the bushing is reduced so that it becomes a bearing wear part in the friction pair). Because of its convenient processing, the replacement cost is low, and it is easy to change. Of course, there is guidance and so on, which is the next.

Feature editing 
The IKO miniature linear bushing bearing is an extremely small straight line motion guiding machine with the rotation of the side and the shaft and the direction of the contact axis in the direction of the axis, and the diameter of the shaft is 3~5mm. The characteristics are: 
1, low friction impedance: the steel ball can be guided by the maintainer, and the steady linear motion is carried out with minimal friction impedance. 
2, stainless steel: also provide stainless steel series, suitable for corrosion resistance requirements. 
3, exquisite design: small size, can be designed in the delicate machinery. 
4, rich changes: in addition to the standard type, there is a series of high rigid long type, can be selected according to use. 


The role of bushing 
The bushing is more flexible in use, and it can play a lot of functions. In general, the bushing is a kind of part for the protection of the equipment. The use of the bushing can reduce the wear, vibration and noise of the equipment, and it has the effect of corrosion protection. The use of the bushing can also facilitate the maintenance of mechanical equipment, the simplification of the structure of the equipment and the manufacturing process. 
The role played by the bushing in the actual work has a great relationship with its application environment and purpose. In the field of application of the valve, the valve cover connection device in the bushing is the stem, in order to reduce the leakage of the valve, so as to achieve the sealing function. In the field of bearing application, the use of the bushing can reduce the wear between the bearing and the shaft seat, and avoid the increase of the gap between the shaft and the hole. [2] 
Lining material 
The material of the bushing is mostly soft metal, rubber, nylon and nonmetal polymer, which are relatively soft and low in price. In all kinds of harsh working environments, bushings are protected by vibration, friction and corrosion. The bushing itself is easy to replace, low cost and economical after damage. 
Selection factors of bushing 
Bushings are widely used and have many kinds. If we want to choose suitable bushing, we must consider its purpose and choose different types of bushings at different working conditions. The main considerations in the selection of the bushing are the pressure, velocity, pressure, velocity, and load properties of the bushing. In addition, the bushing is lubricated, lubricated state also determines its use effect and life. [2]
