There are several reasons that a linear guide rail may be supplied in multiple sections rather than in one piece: the overall length is longer than the maximum offered by the manufacturer, the machine design or other space constraints don’t allow installation of a single piece in the length needed, or the risk of damage […]
How to calculate hole spacing for linear guide rails
Profiled linear guides—whether profiled rails, cam roller guides, shaft support rails, or plain bearing guides—are typically manufactured with evenly spaced mounting holes that allow them to be secured to a machine base or work surface. For rigidity and integrity of the rail, there’s often a minimum distance, specified by the manufacturer, that must be maintained […]
When to use cam roller guides. (Hint: it’s more often than you think.)
With so many linear guide choices—from roller rails to plastic wheels—deciding which technology is right for your application can be difficult. On one hand, not every application requires machine tool rigidity and the ability to move a small car. But on the other hand, most applications require a guide that can withstand high duty cycles […]
