How to Roll with Linear Roller Bearings
Linear Roller Bearings
Linear roller bearings do exactly what it sounds like they do. They “bear” the weight of an object while it “rolls” along the “linear” path set out for it. It is a simple concept that works in a practical way and requires very little maintenance or expense, which is why such a simple concept is still so popular in our technologically advanced society. You don’t mess with something that is cheap as well as working well, even if advances in other areas are being made. Rolling with the linear roller bearings is smart financially and practically, for a number of industries.
The basics of the system involves what looks like a flat and smooth ruler with raised edges on either side that is filled with rolling pins connected to the raised edges while retaining the ability to rotate. Sizes as well as other specific measurements are often done on an individual basis, although there are standard sizes and materials available from linear bearing manufacturers. Usually, whatever aspect of an object that needs to move along the linear roller bearing axis is altered to fit comfortably within the bearing structure, allowing for friction-free movement back and forth. Another possibility is the attachment of a metallic or plastic match to the linear bearing that buffers the product from direct contact with the rollers.
Applications for linear roller bearings, as well as other linear bearing models such as linear ball bearings and linear rotary bearings, include automotive and aerospace systems, medical beds and platforms, manufacturing machinery, robotic automation and residential and commercial furniture such as desk drawers and filing cabinets. The only difference between linear roller bearings and other models are the basic structure of the movement element. For example, instead of rollers there may be balls that allow for smooth motion in a desk drawer.
