Top Of The Rail

Different factors affect the effectiveness of a top of the rail. One, it’s the load requirements. Here check the linear guide weight capacity and size before purchase to make sure you order a machine that will support your intended use. Secondly, check the orientation of the slide. This will help you know the motion and location of a load; hence, you can determine the repeatability and accuracy of the load. Since linear guides come with different orientations and mounting types, this will guide you in choosing the right top of the rail for your application. Third, make sure you know the installation requirements and the application design before ordering a top of the rail online. With that, you can determine which linear guide is ideal for your application. Check also whether a machine has a self-lubricating feature which can be either grease fittings or polymer place. These features supply lubrication to your slide bearings, enhancing the effectiveness of the system. It also increases the linear guide durability as the lubrication reduces friction which can cause damage to the linear guide. You should also check the linear guide durability as buying a durable product will reduce the maintenance and repair cost.

There are two categories of linear guides; plain bearing slides and roller or ball bearing slides. The plain bearing slides use plain surface bearings that have minimum lubrication and friction. This top of the rail is strong and fit for both lateral and radial loads. They include dovetail slides, cylindrical column slides, and Boxway slides. On the other hand, bearing slides rely on a roller element that minimizes friction. They are ideal for light-duty uses as the bearing tends to break or deform when high pressure is applied.
