Linear Roller Bearings

Linear Roller Bearings

Linear roller bearings are a type of rolling-element bearing, meaning they carry a load by placing round elements between two objects. For linear roller bearings, the round objects are cylinders with a greater length than diameter.

One of the most primitive types of roller bearings is a simple set of logs laid along a path for rolling heavy objects. As the object is pulled along the logs, relatively little friction is produced compared with pulling it along a flat surface. Modern roller bearings operate on the same principles.

Linear roller bearings are used in a wide variety of applications. They are cheap and easy to implement. Roller bearings are also able to carry a much heavier load than ball bearings because their cylindrical shape spreads the load over a line rather than a point.
