Schematic representation of floating bearings

Floating bearings for linear slide guides

In the case of a system with two parallel guides, one side needs tobe configured with floating bearings. A suitable solution comprising fixed & floating bearings is available forevery orientation, whether horizontal, vertical or lateral. This type ofassembly prevents jamming and blockage on the guides resulting from discrepancies in parallelism. Floating bearings are created through a controlled extension of play in the direction of theexpected parallelism error. This creates an additional degree of freedomon one side. During assembly, it must be ensured that the floating bearings exhibit a similar degree of play in both directions.The contact surfaces on the guides and carriages should be sufficientlyflat (for instance, milled down) to prevent strains from occurring in the system.

Eccentric Forces

To ensure successful use of maintenance-free DryLin® linear bearings, it is necessary to follow certain recommendations:If the distance between the driving force point and the fixed bearingsis more than twice the bearing spacing (2:1 rule), a static friction valueof 0.25 can theoretically result in jamming on the guides. This principleapplies regardless of the value of the load or drive force.

The friction product is always related to the fixed bearings. The greater the distance between the drive and guide bearings, the higher the degree of wear and required drive force. Failure to observe the 2:1 rule during a use of linear slide bearings canresult in uneven motion or even system blockage. Such situations canoften be remedied with relatively simple modifications. If you have any questions on design and/or assembly, please contactour application engineers.
