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.

[China Agricultural Machinery Industry News] Agricultural electromechanical businessmen are indispensable in today's modern agricultural production. Not long ago, "Internet +" played a major role in solving the problem of Guangzhou Xuwen pineapple slow sales. However, the development of e-commerce still has problems. Due to the constraints of agricultural machinery subsidies and the characteristics of agricultural machinery products, the development of agricultural electromechanical business still needs to have a long way to go.
"Two" factors restrict the development of "Internet +", and there is still a long way to go.
Along with the development of the Internet, especially the popularity of the "Internet +" boom after the two sessions last year, as the cross-border integration of the agricultural machinery industry and the Internet in the traditional manufacturing field, it has also entered the people's field of vision. Up to now, leading enterprises including China Yituo, Shandong Wuzheng, Zoomlion and other industries have established their own online stores or have online marketing initiatives. The foreign-funded enterprises in China, Aike, also broke out with well-known Internet companies. Cooperation news. In addition, since last year, many agricultural machinery companies have cooperated with industry websites to create the concept of Internet marketing. Of course, compared with tens of thousands of agricultural machinery companies across the country, more agricultural machinery enterprises, especially host enterprises, are still waiting to see.
From the current situation, the agricultural and electrical machinery business has the following two major factors. The first is the limitation of the agricultural machinery subsidy policy. Secondly, the characteristics of the agricultural machinery products themselves are constrained: First, the network operators can not meet the after-sales; second, the online shopping products are difficult to deliver. It is precisely because of the current insignificance of agricultural and electrical traders, the contradiction between online and offline has not been clearly exposed. Once the network direct sales rise, it will not avoid the collision between online direct sales and offline dealers.
Of course, agricultural machinery and electronics may be the future development trend, and the agricultural machinery industry needs to actively research and innovate agricultural machinery and electronics. The development of agricultural electromechanical business is highly correlated with national macroeconomic policies, social development stages, technological changes, quality and services. Perhaps, with the real benefits of agricultural machinery subsidies (no matter who buys and pays for it), the rural informationization (network, computer, mobile phone and other software and hardware conditions) continue to advance, the cultural quality of agricultural practitioners continues to improve, and China The quality of agricultural machinery products continues to strengthen, and agricultural and electrical machinery companies will usher in a real outbreak. However, from the current situation, the agricultural and electrical machinery business still needs to go through a long process of accumulation.
