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

WE Type – Four-Row Wide Rail Linear Guideway


The WE series features equal load ratings in the radial, reverse radial, and the lateral direction with contact points at 45 degrees. This, along with the wide rail, allows the guideway to be rated for high loads, moments, and rigidity. By design, it has self-aligning capacity that can absorb most installation errors and can meet high accuracy standards. The ability to use a single rail and to have the low profile with a low center of gravity is ideal where space is limited and/or high moments are required.
