Lishui City (susan1125.b2b.hc360.com/) is specialized in the "build bearing production projects, bearings and hardware accessories sales" of the enterprise, the company adhering to the "honesty, hard service" concept, for you provide the highest quality products and services. Welcome to inquire! Contact: Chen Zujiang. Most industrial rail made of steel or cast iron linear slide rails, sliding rails in the long-term use, because there are different degrees of friction between the two contact surfaces, can cause varying degrees of rail surface scratches and pulled the slide rails Bearings, seriously affecting the machining accuracy and productivity equipment. Traditional repair methods commonly used metal plates veneered or replace other methods, but it requires a lot of precise manufacturing and manual scraping, step repair requires more long duration. Machine Tool against scratches and strain problems can be solved using polymer composites. Since the material has excellent adhesion, compressive strength and oil resistance, wear resistance, provides a permanent protective layer for the component. Just a few hours to the site of the rail scratch repair is completed, put into use, compared to the traditional method of operation more simple, less the cost. Spherical plain bearings can withstand a greater load. According to their different types and structures that can withstand the radial load, axial load or radial, axial joint load simultaneously. Since the outer spherical surface of the inner ring inlaid with composite materials, so that the bearing can be generated in the work of self-lubricating. Generally used for lower-speed swing motion miniature slide rails, and low-speed rotation, but also for tilting movement within a certain range of angles, when the supporting shaft and shaft housing bore large misalignment, still work. Self-lubricating bearings used in water conservancy, specialized machinery and other industries.
