A Linear rail system is a device that supports the weight and movement of a piece of equipment in a linear or straightway either vertically or horizontally. It does the job well by levitating heavier loads that can be difficult for humans to lift and can potentially harm them if not lifted correctly. With the arrival of linear rails, the human effort has been minimalized as the rails are used to lift and move products or goods.
Linear rails have a variety of names including linear guide rails, linear guideways, linear guides, linear slides and linear guidance systems. So many names that you might get confused by them. Linear rail moves heavy loads along a linear path with a minimum amount of friction or resistance.
What Is It Made of?
The rails are usually made of high-strength, hardened and galvanised steel, hence they are corrosion resistant. These are manufactured using a cold drawing process. This means that the metal is bent and shaped before a roller runner is added. Profiled rail guides are suitable for high loads and to deliver a precise linear motion. They come in many sizes and shapes suiting your demands.
Size and Load Capacity
Linear rails work better than any other guide devices because of its sizes, rigidity and load capacity. Many industries thus incorporate linear rails to do their jobs. When you need a guide system with low friction and high rigidity for loads weighing, linear rails will be the most suitable guide.
Let’s talk about the load capacity, shall we? Linear rail guides can withstand downward loads, lift moment loads and moment loads. Another benefit of linear rail guides is that it can deliver long travel increased stiffness and rigidity compared to the crossed roller guides.
Maintenance of The Guides
Under-lubricated guides tend to wear out pretty easily. This can result in problems with its performance and cause premature failure. Lubrication can make all the difference; the quality of lubrication solely depends on the quality of the lubricant applied. But some guides come with automated lubrication systems, so you don’t have to hassle with lubricating it. However, these guides can be pretty expensive and are complicated to operate. Maintenance-free bearings are cheap linear bearing shafts that are much simpler and have mechanical features added to the bearing slider to store and deliver the lubricant.
To maintain the guide’s health, one thing you can do while checking for problems is looking and listening to the guide. It might sound strange but sometimes a change in sound that the system makes can indicate that it isn’t lubricated enough. Take a door for an example, when you hear an unusual creak from your door, you’d immediately know it needs lubrication. Similarly, you can hear the unusual sound coming from the system if you listen carefully. The guide rails make sounds when they are misaligned or there’s any blockage. When you suspect a potential problem, opening the seals which keep dirt out and lubricate the rails and inspect can help. You can even replace the seal easily if you find any damage or dirt in it.
