Special enhancements to improve accuracy and efficiency in linear motion are available.  OK rolling ring drives are unmatched at lowering production and maintenance costs while boosting productivity.

In broader linear motion markets, such as the OEM design engineering market, SOHO provides expert rolling ring linear motion guidance to explain when and how to use OK rolling ring technology to improve productivity and efficiency.  Now our products have been sold all over the world.  Continuously renewed and updated, the third generation products of aluminium alloy with the craftsmanship and technology introduced from Germany deliver superior performances.
