1 Low-Profile Linear Guide System Low-Profile height and width Replaceable polymer sliding pads Anodized aluminium rail High speed and acceleration possible Lubrication-free Light weight 62.1

2 Low-Profile Linear Guide System The low-profile range offers extremely low profiles in several widths. Like all DryLin products the carriages run without grease or oil in an anodized aluminium profile. The selected materials and the unique design make a cost-effective and flexible guide system.

LLYZ LLZ Floating in z-direction LLY Floating in y-direction LLYZ Floating in yz-direction Floating bearings for linear slide guides In the case of a system with two parallel guides, one side needs to be configured with floating bearings. A suitable solution comprising fixed & floating bearings is available for every orientation, whether horizontal, vertical or lateral. This type of assembly 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 the expected parallelism error. This creates an additional degree of freedom on 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 sufficiently flat (for instance, milled down) to prevent strains from occurring in the system. Floating Fixed Automatic compensation of parallelism errors 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 bearings is more than twice the bearing spacing (2:1 rule), a static friction value of 0.25 can theoretically result in jamming on the guides. This principle applies regardless of the value of the load or drive force. Floating Fixed 2 x 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 can result in uneven motion or even system blockage. Such situations can often be remedied with relatively simple modifications. If you have any questions on design and/or assembly, please contact our application engineers. 1x The 2:1 Rule Clean room suitability and ESD-compatibility You can find detailed information on Page
