Based on high proprietary processing technology, strict dimensional control is made on the slide unit and external cylinder as well as the track rail and spline shaft, and an unparalleled high interchangeability level is exhibited.
It is a product selection system based on the user’s viewpoint.
  
Units of various forms (External Cylinder) can be combined on the same rail (Shaft), and it is possible to add or replace each unit. Therefore, replacing parts based on sudden changes in the specifications is easy.
Since inventory control of the unit (external cylinder) and rail (shaft) can be conducted singly, it is possible to respond to short term delivery.
Since strict accuracy control is conducted in units of parts, it is possible to make settings of accuracy classes or high preload.
Normally, when a plurality of sets is assembled, it is necessary to control the combination of units (external cylinder) and rails (spline shaft) for each set. In the case of Interchangeable products, set control at the time of assembly work is not required, and it is instrumental in conducting the work efficiently.
There are lots of variations of form, size, and types of materials, etc., and the optimum product can be selected for all applications.
To match the various applications, standards corresponding to abundant options are available. Designation can be made by adding supplementary symbols to the arrangement of bearing numbers.
As for the slide units, numerous types are available in terms of shape of cross-section and length. Any of these can be combined freely on the same track rail. Furthermore, the track rails can also be connected for use.
Accuracies are classified into three classes, namely, Ordinary Class, Upper Class and Precision Class. Thus, it is possible to correspond to applications that require high running accuracy. In addition, since the mutual difference of heights is controlled with high accuracy for a plurality of sets, even when track rails are used in parallel, they can be used with a sense of security.
Since high accuracy dimensional control that makes the most of simple structures is conducted, we were able to realize the interchangeability of a slide unit to which preload is given.
In addition, several preload areas are set, making it possible to handle applications that require rigidity which is of one rank higher.
