Linear bearing installation advantages and selection methods have?

Linear bearing is a kind of mechanical metal products on the market, is mainly made of metal. Linear bearing has a long service life, corrosion resistance and the characteristics of anti-rust, easiness of maintenance and replacement, so it is widely applied. Today the author is to introduce for everybody linear bearing installation methods, advantages and selection method. Linear bearing installation method 1, before installation of linear bearing must first clear machinery installation the burrs, dirt and surface scars. Linear bearing coated with anti-rust oil, before installation, please use clean oil wash the datum after installation, it usually remove the rust easily after anti-rust oil, datum suggest using lubricating oil with low viscosity daub spindle. 2, will use linear bearing placed gently on the bed, with lateral fixed screw or other fixed fixture make face gently joint and lateral line rail installation. Make sure it fits the screw holes before install and use, assuming base processing holes don't match and forcibly lock bolt, will greatly effect the precision of combination with the use of quality. 3, from the central to both sides in order to linear bearing positioning screw tightening, orbit and the vertical mounting surface laminating, forced by a central location to both ends can get relatively stable precision. After vertical datum plane is a bit tight, strengthening lateral datum of the locking force, make the linear bearing to joint lateral datum. 4, use the torque wrench in accordance with various material clamping torque, position of linear bearing slides slowly tightening the screws. 5 vice rail installed, use the same way, the individual installation and slide to the rail and vice on the rail. After attention slide fitted linear slide rail, subsequent many affiliated parts due to the limited installation space can't install, must accessory installation will be requested at this stage. 6, gently put mobile platform to the linear bearing the main rail with vice rail sliding seat, then lock the lateral force screw of the mobile platform, can be done after installation location. The advantages of linear bearing 1, to the load increase, but the friction coefficient is not sensitive to changes, so under heavy load, small friction coefficient, and the accuracy unchanged for a long time, can get mechanical service life is long. 2, sides of additional oil seal bearing dust also apply to more easily invaded by a foreign body or places. 3, linear bearing interchangeability, easy installation and use to save time, and make the mechanical structure is novel, small, lightweight characteristic. 4, due to the flow of contact can make the starting friction resistance and dynamic friction resistance is minimal, so it can save energy, easy to get a high speed. 5, save for oil formalities, simplifies the lubrication and maintenance. Linear bearing selection method 1, practical aspects of linear bearing. Don't blindly focus on when choosing linear bearing brand, of course, the quality of the brand is relatively better, but some ordinary linear bearing were adopted for design can be solved, they don't have to be sure to use the brand of bearing. 2, determine the scale and model of linear bearing, when choosing linear bearing according to their own needs, choose from set out actually, there are a number of manufacturers specifications, but some linear bearing only a small amount of production or can make to order, only to wait for a long time, want to choose market commonly used linear bearing. The above is to introduce the author linear bearing installation methods, advantages and the entire content of the selection method. Linear bearing is composed of a cylindrical outer ring and multi-column steel ball and adhere to the frame, bearing can do reciprocating linear motion on the shaft. Linear bearing on installation there are many places need to be aware of, so you must be more careful.
