HIWIN WEH27 Linear Guide Block | Wide Type High Moment Linear Way

November 26, 2025
Product Overview You are viewing the HIWIN WEH27, a high-performance block from the WE Series (Wide Type). Unlike standard linear guides, the WE series is engineered with a wider rail-to-block contact area. This unique design enables the guideway to withstand significantly higher moment loads and torque, making it possible to use a single rail where two parallel rails might otherwise be needed—saving both cost and installation space.

Key Features:

High Moment Capability: The wide rail design allows for high permissible moments in the rolling direction, providing superior stability for single-rail applications.

Low Profile & Compact: The low assembly height and low center of gravity make it perfect for compact devices and limited-space machinery.

4-Row Ball Design: Features a 45° contact angle for equal load capacity in all directions (radial, reverse radial, and lateral).

Self-Aligning: The DF (Face-to-Face) circular-arc groove design absorbs installation errors, ensuring smooth motion even under heavy loads.

Dust Protection: Comes with standard end seals and side seals (as shown in the video: Red End Caps / Green Side Strips) to prevent contamination.
