  • Linear Bearings: Understanding the 2:1 Ratio and How

    2021-3-20 · The “Binding Ratio” is officially defined as the maximum ratio of moment arm distance to bearing length which will not bind (prevent motion). The Binding Ratio is often displayed numerically as “X:Y,” where “X” is the moment arm distance and “Y” is bearing length. Typically, the value of “X” is divided by “Y” so that the ...

  • What You Need to Know about the 2:1 Ratio - Linear

    CAUTION: Binding will occur if the 2:1 ratio is exceeded. Note: This principle is NOT load dependent. It is NOT due to edge loading. It is also NOT dependent on the driving force used. The bearings will bind whether hand or mechanically driven. The 2:1 principle for linear plain bearings and the resulting binding is a product of friction.

  • Demystifying the 2:1 Ratio in Cantilevered Loads -

    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 Rolling Bearings - University of Utah

    If you choose a hybrid bearing, you can reduce the push-force by 0.5 pounds for every 10 pounds of radial load. Twenty-five pounds of push-force is the upper limit of an average person’s capacity. Therefore, with regular linear bearings, approximately 100 pounds of radial load would be the upper limit of a person’s capacity to push manually.
