EGR + EGH / EGW Slider Series – Low-Assembly Ball Linear Guideway
The EGH/EGW series is our low-assembly ball linear guideway product, paired with EGR series guide rails. Featuring reduced assembly height and shortened slider length, it is ideal for compact equipment with limited space. It follows the widely copied EG low-assembly footprint family; verify mounting dimensions per size before substituting. Available in both carbon steel and stainless steel material options, suitable for high-speed automation equipment, medical instruments, inspection devices, and other space-constrained applications. Offered in standard (CA/CC) and extended (HA/HC) slider types, as well as square (EGH) and flange (EGW) mounting styles.
Key Features
- Assembly Replacement – Direct replacement of existing same-series assemblies (slider + EGR guide rail) in customer equipment
- Low-Assembly Design – Reduced assembly height and shortened slider length, optimized for compact equipment with limited space
- Extended Type (HA/HC) – Longer slider body delivers higher dynamic load rating and rigidity than standard type
- Flange Option (EGW) – Mounting holes located on both sides of the slider; can be secured from top or side for greater installation flexibility
- High Positioning Accuracy – Precision machining processes meet demanding displacement accuracy requirements
- Hardened Surface – Guide rails undergo surface hardening treatment for excellent wear resistance and long service life
