FÖHRENBACH GMBH - Positioniersysteme

The RK line is equipped with a cross type handle and, from size 300 on, with a hand wheel. Our slides that run on roller bearings, in single-axis or multi-axis designs, are supplied in the materials grey cast iron and aluminium. The roller bearing slides run in preloaded, hardened and ground Vee-guides. This ensures a smooth, zero-play and extremely precise longitudinal movement - even under high load. Slides which must be designed with T-grooves or higher rigidity can be produced in a reinforced version.

The RH line is equipped with a hand wheel and a scale ring with a 0.02 mm scale gradation. Sizes 075 up to 200 can, on option, also be furnished with a 0.01 mm scale gradation.

The RA line descripes a roller beared slide in a special sealed version. The standard type is equipped with a gap seal (approx. 0.5 mm). Special types with felt or nylon scrapers are possible, too.

Our cross roller guide rails are freely interchangeable standard elements. Our guide rails allow the assembly of extremely rigid and precise linear guides without any play. Benefits Able to carry high loads running extremely smooth require little space long serviceable life Mounting instructions: When mounting the guide rails make sure the bearing surfaces have been machined in a parallel manner and are to the angle. The tolerances of the bearing and mounting surfaces shall conform to the process tolerances of the guide rails (standard quality). The prestress applied depends on the respective mounting conditions, on the rigidity of the assembled slide structure respectively. We recommend to apply a prestress equivalent to a value between 5 and 20 % of the maximum admissible load. However, the load carrying ability of the overall guide rail structure thus realized will, at any case, be reduced by the prestress applied.

The miniature roller slides can be delivered either as open type or with end plates. The exterior part is made of aluminium, the interior part consists of hardened steel. With standard drilling pattern.

This guiding system makes it possible to accurately position your products. Furthermore, you can fix it exactly at the desired place. The innovation lies in the backlash-free clamping, horizontal and vertical side misalignment ≤ 3 μm. Useful advantages: compact sizes and the possibility of adjusting and locking the guide by a hex screwdriver. Clamps permit a fast combination to 2 axis systems and/or 3 axis systems or the fitting of axis systems on a base plate. Features Dovetail slides made of Aluminium, natural anodized 5 sizes: 20, 30, 50, 80, 120 mm with standard stroke between 5 and 100 mm Backlash-free clamping Compact sizes Adjustment with knurled micrometer knob (standard) or hex screwdriver High load ratings Guides without play High damping Scale with knurled micrometer knob Mounting kit (clamps) Easy and quick to combine to 2 axis systems and/or 3 axis systems Optional position readout (starting from size 30 mm)

The highest accuracy class “Ultra-Precision plus” impresses with an accuracy of 0.0005 mm, thus 0.5 µm. Due to the fact that the control unit of the Föhrenbach slides is compatible with the interfaces of almost all measuring systems, this extraordinary repeatability does not depend on a particular system or a specific provider. Föhrenbach profiled guide slides with integrated linear motor are available in the series PFL (with bellows covers) and PCL (with sheet metal covers). For both series three sizes are available. We developed three resp. two linear motors of different force.
