  • Linear Bearings and Rail Guides – Trimantec

    When using DryLin® linear guides, it is important to ensure that all acting forces follow the 2:1 rule. In a nutshell, if either the drive force (Fa) or applied load force (Fs) are a greater distance than twice the bearing length (wx), then a binding or chattering of the system can occur.

  • Linear Bearings | RS Components

    Linear plain bearings are bearing elements for translation type motion (motion along a path). Unlike roller bearings, linear plain bearings move on a shaft or static guideway, as opposed to on movable component slides. Depending on the type of guiding system, the sliding layer is applied to the rigid or movable component.
