Ball bearings to adapt to a variety of purposes, providing a wide range of standardized products. Widely used in machine tools ball screw, ball circulation methods are circulating duct type, circulator type, cover type. Preloading way positioning preload (double nut way preload-bit mode), constant pressure preload. May be appropriately selected according to the type of use. There are high-precision grinding screw precision ball screws (accuracy divided from CO-C7 of six levels) and by high-precision cold-rolled ball screw bearings molding (precision into the C7-C10 3 grades) Ball bearings over the years accumulated technology-based products, from materials, heat outside the grounds, manufacture, inspection to shipment, are based on strict quality assurance system to be managed wholesale ball screw, so it has a high reliability. Linear guide is a kind of low-cost consumer manufacturers of ball screw linear motion system for unlimited travel with the cylinder axis with the use. Because carrying the ball point contact with the shaft, so the use of a small load. Ball with minimal friction ball screw rotation Which is good, so that it can obtain high-precision smooth movement. Linear slide rails commonly used electronic equipment, tensile testing machine and digital three-dimensional coordinate measuring equipment and other fine equipment, as well as multi-axis machine tools, presses, tool grinder, automatic gas cutting machine, printer, card sorting machine, food packaging machines and other industrial machinery components.
