Sealing systems

The HIWIN end seals firstly prevent the ingress of foreign substances such as dust particles, chips or liquid into the block’s ball tracks and secondly reduce the amount of lubricant lost. HIWIN provides various sealing systems for the various ambient conditions of your application. The effectiveness of the end seal impacts directly on the lifetime of the linear guideway and should therefore be taken into account at the design stage and selected to suit the ambient conditions of your application.
