EGH25CA Linear Guide

EGH25CA Linear Guide

Product Description

The EGH25CA is a low-profile linear guide block engineered for automation applications where vertical space is constrained, yet load capacity and structural rigidity remain essential. Featuring a 33 mm assembly height and an 82.1 mm block body, this standard square block allows machine designers to integrate heavy-duty linear motion into compact physical envelopes.

Four-Bolt Stability for Dynamic Axes
The "CA" designation indicates a heavy-load, standard-length carriage body. Weighing 0.41 kg, the EGH25CA features four M6 threaded mounting holes in a 35 mm × 35 mm pattern. This square configuration provides a stable mounting platform that distributes forces evenly, making it well-suited for high-speed pick-and-place systems, automated inspection stages, and light CNC machining heads requiring consistent stiffness during rapid cycling.

Omni-Directional Loading & Self-Aligning Technology
By employing a symmetrical four-row ball configuration with a 45-degree contact angle, the EGH25CA offers identical load capacities in radial, reverse-radial, and lateral orientations. The circular-arc groove design provides high stiffness while maintaining a self-aligning capability that absorbs minor mounting bed inaccuracies, supporting consistent positioning accuracy and a long, low-friction service life.

Product Components
Square Carriage Body: Precision-machined, low-profile high-strength steel block (Mass: 0.41 kg) featuring a flat top-mounting face.
Recirculating Rolling Elements: Precision-hardened chromium steel balls optimized for wear resistance and consistent contact performance.
Deflector End Caps: High-impact resin components designed with internal return paths for smooth, low-friction ball redirection.
Integrated Ball Retainers: Specialized metal wire guides engineered to prevent ball loss when the block is removed from the rail during installation or maintenance.
Tri-Shield Sealing Kit: Comprehensive integrated sealing configuration (end, bottom, and side seals) designed to exclude debris and retain internal lubricants.
Lubrication Nipple: Includes an end-cap mounted M6 grease fitting for direct and convenient grease or oil replenishment.
