Without lubrication, the running surfaces of linear guideways are completely destroyed after only 10,000 revolutions.
A guideway coated with DryRunner allows for more than 100 million revolutions without lubrication and thus a service life that is 10,000 times longer. In a vacuum, an unlubricated guideway coated with DryRunner allows more than 50 million revolutions.
To achieve outstanding running performance, we recommend the DryRunner coating in combination with minimal lubrication using a common lubricant.

- The coating is only applied to the running surfaces. From a production standpoint, it is possible to coat other exterior surfaces but not the supporting and locating surfaces of the guideway.
- DryRunner does not provide any protection against corrosion. If corrosion-resistant guideways are required, the guideway must be ordered in a rust-resistant material (RF) or with a Duralloy coating (DU).
The advantages of DryRunner
- Good emergency running properties with insufficient lubrication
- Suitable for applications in air or vacuum
- Minimal wear due to abrasion
- High chemical resistance
Notes:
- DryRunner permits operation with minimal lubrication.
- We recommend using the FORMULA-S cage control (KS) (see section 7.8).
- The special version of the multi-part linear guideway ZG and the quality class SSQ are not possible. Quality class SQ on request (see sections 7.4 and 7.1).
