PH series linear guides are high-precision yet interchangeableNSK is launching the PH series series high-precision linear guides at the EMO trade fair. According to NSK, high precision can be achieved even when interchanging carriages and rails thanks to an optimised production processes for the guide rails. This interchangeability is said to be particularly beneficial for machine tools.

In the past, designers had to opt for high precision and performance or sacrifice accuracy for the sake of freely interchangeable carriages and guide rails. The PH linear guides, however, which NSK will present for the first time at the EMO trade fair, allow carriages and rails of the same size to be freely combined, where previously this high accuracy was only possible through paired systems. This makes it easier to produce machines and to replace precision linear guides during servicing. Furthermore, the linear guides are available off the shelf.

NSK achieved this simplification by optimising production processes and manufacturing to tighter tolerances. This means that higher precision rails and carriages can now be freely combined. Just like NSK's existing ranges of linear guides, products from the PH series are self-aligning, which makes mounting easier.

The new PH class is available with various different guide carriage types in sizes 15 to 45. All of the designs run much smoother and boast significantly better guaranteed precision than the existing PC class, which already offers very good performance. As for its other series, NSK offers a wide range of options for the new linear guides, such as K1 lubrication units and various types of wipers.

With these properties, the PH linear guides are suitable for applications that require very quiet running. The linear units are also rigid enough to be used for demanding applications, especially in the machine tool industry. See the new PH series linear guides on NSK's Stand B16 in Hall 7 at EMO Hannover, which runs from 19-24 September 2011, or contact NSK now for more information.
