Descriptions of bearing LM40UU
Linear plain bearings are linear locating bearings for unlimited stroke lengths. These linear guidance systems are available as a miniature plain guidance system, linear plain bearings and linear plain bearing units as well as a flat guidance system
Linear block is divied to flange type and slim type without flange. Also, linear block is divided to high load capacity with standard block lenth and ultra high load capacity with longer block length.
"UU" means rubber seals on the both sides of the long type bearing

| Description | A linear-motion bearing is a kind of bearing that aims at offering free motion in one dimension. The structure of the liner motion bearing is that a retainer is built in the outer ring. And the retainer is equipped with many steel balls doing infinite circulatory movement. Besides, the two ends of the retainer are fixed with the spring collar. There is a side window in the straight track. This section is allowing the loaded balls and the axis to do the rolling contact. These products can move relatively under a very low coefficient of friction. Therefore, the linear motion bearings are appropriate for many mechanical equipments, automation equipments, and energy-saving equipments, etc. | ||||||||||||
| Use | Like many other kinds of bearing products, linear motion bearings have a quite wide range of application. At present, they are more widely used in the electronics, machinery, equipment, robots, tools, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machine tools, automobiles and many other mechanical industries. | ||||||||||||
| Category | There are various kinds of linear motion bearing. Generally, it can be divided into rolling-element bearings and plane bearings. The former has the characteristics of smooth motion, low friction, high rigidity and long life. It is quite easy to maintain and replace these products. The latter category is very similar in design with the rolling-element bearings. They can perform on hardened steel or stainless steel raceways. | ||||||||||||
| Feature | 1.Full range of profile sizes – miniature (3, 5, 7, 9, 12, and 15mm) and standard (15, 20, 25, and 30mm) | ||||||||||||
| Advantage | There are many advantages of using linear motion ball bearing. Firstly, the mobile access can make the starting friction resistance and dynamic friction resistance become extremely small. Thus, this can help to save energy and make easier to get a higher velocity. Secondly, it changes little under the increasing of loads. Besides, it is not sensitive to friction coefficient changes. Therefore, the friction coefficient is extremely small under the heavy load. Except for this, it can maintain the long-term accuracy which can lead to the longer life of the machines. Thirdly, the liner motion bearings have quite good interchangeability. It is easy to be installed. Besides, it makes the mechanical structures small and light. Fourthly, it can simplify the process of lubrication and maintenance. | ||||||||||||
