Linear Roller Bearings

In numerous precision movement applications, the linear motion bearing can be found. These products are able to provide smooth linear motion for the objects in which they are used for. When it comes to deciding the perfect linear bearing, rotary bearings can be the right choice. A linear rotary bearing is able to combine multiple linear bearing technologies to provide the smooth and low friction movement on a straight line. Typically, they are found in manufacturing, medical, construction and agricultural industries. Their applications can include drills, die cutters, engines, industrial robots, automobile assembly lines, dental tools, printing equipment and a vast array of other uses.

Rotary bearings can come in a variety of materials, sizes and specifications to make sure that the precise model that you need is available. Common materials include aluminum, stainless steel, hardened steel, plastics or ceramics. Each material is able to offer its own unique set of benefits and attributes, so each must be thoroughly evaluated before making a final purchase decision. In many ways, these products are similar to another common bearing model, brushings. These models are able so slide along the shaft without the ball bearings, relying instead on lubrication to provide the smooth movement.

Linear rotary bearings are cylindrical in shape. They are smooth, and often polished although whether or not they are polished will depend on the material that is used in their construction. Generally there are only a few centimeters in length and the shaft ranges from around 6 to 20 millimeters in diameter. Like other bearings, they have tracks that are lined with cylindrical ball bearings. The ball bearings within the system are able to reduce the friction by 100 times, and also increase the life of the bearing itself. By using these products correctly, and checking up on them occasionally, it is easy to make sure your motion applications work with the highest levels of precision available.
