1, to achieve functional when browsing the web page ,Dressing Roller wheel with your finger , you can scroll up and down web pages , eliminating the need for moving the mouse and click on the scroll bar of the bitter, very intuitive to use , and thus have Internet mouse wheel mouse reputation. Moreover, including Microsoft Office and many other editing window and the browser window for editing and browsing, scroll wheel can also be replaced easily flip up and down the scroll bar functionality , especially for large document browsing and editing . 2, to achieve in ACDSee Picture Frame turn , when open multiple image files, we usually use the "Tools " column "Previous" and "Next" button before the turn or back pictures. In fact , when using the mouse wheel can easily flip the picture, but also open the folder where the picture is not open all the other pictures. 3, so that the screen automatically scrolls in many editing window , for example, in Word, press the mouse wheel button , it will appear in the editing window and down a black double-headed arrow , move the mouse pointer to the bottom of the double-headed arrow , the screen automatically upwards scrolling, double-headed arrow mouse pointer leaves farther , faster scrolling . To scroll up the screen , simply move the mouse pointer to the double-headed arrow top. 4 , quickly get the best view of the addition to the flip function, wheel mouse Another notable feature is the Ctrl key is pressed , the scroll wheel can easily display the contents of many windows free scaling, to get the best view .
Needle Dressing Roller bearings from the plane with a flat or cylindrical roller and cage assemblies consisting of flat washers . Needle and cylindrical roller being maintained to keep the plane and guide rails. When used with a different series of plane bearing washer can provide many different combinations of the bearing configuration. As the use of precision cylindrical rollers ( needle ) to increase the contact length so that the bearing load capacity and high availability of high stiffness with a very small space. Another advantage is that if parts suitable for use as a surface adjacent raceway can be omitted when the washer , can compact design , flat needle roller bearings and cylindrical roller bearings Needle roller flat and cylindrical roller using cylindrical surface of repair shaped face , edge stress can be reduced , improving life. Needle roller and cage assemblies plane is the main component plane needle bearings . Radial arrangement of the needle bag holder and the guide . The retainer having a specific sectional shape is formed of hardened steel . Small cage with industrial plastics. Precision needle diameter grouping tolerance 0.002mm, to ensure uniform load distribution . Needle roller and cage assemblies plane using shaft boot. Thus , even if the guide surface at high speed can be obtained at relatively low circumferential speeds. If the adjacent raceway surface is designed to save space-saving washers are eligible for special support . If this program can not be implemented , there is sufficient support in the conditions , the use of thin-walled steel washers AS series also enables a compact design . Flat cylindrical roller bearings 811,812,893,874,894 This bearing is composed of a flat cylindrical roller and cage assembly , a positioning ring bearing the GS and an axis positioning WS components. 893,874 and 894 series flat cylindrical roller bearings can be used for higher loads. Flat cylindrical roller bearing cage by high quality steel stamping, but also by industrial plastics , light metals and brass production, user requests according to the environment . Child or ball thrust bearing thrust needle roller or cylindrical roller by the band cage assemblies and thrust washers components. Needle and cylindrical roller thrust being to maintain and keep the guide frame . When used with a different series of thrust bearing washers may provide many different combinations of the bearing configuration. As the use of precision cylindrical rollers ( needle ) to increase the contact length so that the bearing load capacity and high availability of high stiffness with a very small space. Another advantage is that if parts suitable for use as a surface adjacent raceway can be omitted when the washer , can compact design, thrust needle roller bearings and needle roller thrust cylindrical roller bearings and cylindrical roller using cylindrical surface of repair shaped face , edge stress can be reduced , improving life.
