EGW30SA Linear Guide

EGW30SA Linear Guide

Product Description

Series Compatibility: EG Low-Profile Ball-Type Series; runs on standard EGR30 rails.
Dimensions: Assembly Height (H): 42 mm | Flange Width (W): 90 mm | Block Length (L): 69.5 mm.
Mounting Interface: Two M10 threaded holes spaced transversely at 72 mm.
Center of Gravity: 42 mm low profile reduces moment arm distance and dynamic vibration compared to 47 mm high-assembly blocks.
Load Geometry: 4-row ball configuration (45° contact angle) provides equal load capacity in all four directions.
Self-Alignment: Circular-arc DF groove architecture absorbs minor mounting bed inaccuracies to prevent binding.
Applications: Compact automation axes, semiconductor machinery, and pick-and-place systems with restricted vertical clearance.

EGW30SA Performance Highlights
Materials & Build: Precision-ground alloy steel body with hardened GCr15 steel balls.
Dimensions: 42 mm assembly height (H) | 90 mm flanged width (W) | 69.5 mm block length (L).
Low Inertia: Compact 0.62 kg carriage mass optimized for rapid acceleration and high cycle rates.
4-Way Equal Loading: Symmetrical 45° contact angle supports equal loads in all orientations.
Contaminant Exclusion: Tri-Shield end and bottom seals protect internal raceways.
Handling Protection: Built-in wire retainers prevent bearing loss during installation.
Self-Alignment: Circular-arc groove design compensates for minor mounting surface unevenness.
