Steel Liner

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 main conditions are: pressure, velocity, pressure velocity product, lubrication condition, load property. Bushing fast and easy to select the best automatic selection.

Wrapped in stem, worn out, can be easily replaced. If you do not use the bushing, wear, replace the parts. So replace the bushing (design, it will reduce the hardness of the bushing, making it in the friction pair as a bearing wear parts.). Because of its easy processing, low replacement cost, but also easy to change. Of course, as well as the guiding role, is the second.

Low frictional resistance:

Because of the correct orientation ball retainer, linear motion stability with minimal friction resistance

Stainless steel:

Also provide stainless steel series, suitable for the use of corrosion resistance requirements

Exquisite design:

Small size, can be designed in sophisticated machinery / equipment

Rich change:

In addition to the standard type, there are a series of high rigid long type, can be selected in accordance with the use.
