Linear Roller Bearings
The linear bearing industry never rests. It seems like everyday new and improved models are coming out that can provide the precision movement that customers want from their linear bearings. They can be used for applications such as drawers, height adjustment mounts, optic alignment, precision dispensing, wafer testing and automated production equipment. Their wide range of uses makes them available in various sizes, materials and other modifications. Custom options are often available by certain manufacturers as well to make sure the product is the perfect match for the future application.
As these products continue to become more advanced, they are able to assist in increasingly difficult applications. For example, newer models are able to provide assistance in space-restricted applications. Then there are options such as plain bearings. While most bearings that are typically thought of contain ball bearings, the plain bearing does not, but aside from that one modification is very similar in design and application to the linear motion bearing. The plain bearing is able to run on hardened or stainless steel shafting. It can also be run on various aluminums. The main differences to consider are that these models are less rigid and can handle wider temperatures than the traditional models. Also, they can handle contamination easier, and may not require sealants or scrapers. Finally, while most ball bearings will require lubrication, plastic versions of the plain bearing do not require this.
The type of bearing best for the application that it is being applied to can vary, sometimes a couple different types might even work. Linear bearing companies are willing to work closely with customers to make sure that the right model is selected to provide the ideal level of precision and the knowledge to care for and keep the product running for a long period of time.
