EGH Series Linear Guide

EGH Series Linear Guide

Product descriptions

The EGH Series is categorized as a High-Assembly, Low-Profile Recirculating Ball Profiled Rail Guide. It uses the same high-load, 45-degree contact angle as the EG/EGW models but features a block that is taller in its cross-section.

Its primary functions include:

High Rigidity in a Compact Footprint: The taller profile of the block provides enhanced rigidity, particularly against pitch and yaw moments, compared to a block of the same length and width, while still maintaining the overall benefits of a low-height rail.

Facilitating Short, High-Accuracy Strokes: It is frequently chosen for applications requiring high precision and stiffness over short travel distances, where a small block length is preferred to save space.

Use in Paired Systems: The EGH's enhanced stiffness makes it an excellent choice for being mounted in a pair (two parallel rails) for heavy-duty, compact applications.

The EGH Series is used in CNC machining centers (where compactness and rigidity are crucial), tool changers, and various types of measuring instruments.

Component Parts

The EGH series is an integrated system consisting of:

The EG Guide Rail: A hardened, precision-ground steel rail with the standard EG low-profile cross-section. It features the meticulously shaped Gothic arch raceway grooves.

The EGH Bearing Block (Carriage): A tall, compact steel housing that travels along the rail. It contains the recirculating ball bearings, the ball return elements (end caps), and robust wiper seals to maintain lubrication and exclude contaminants.

Rolling Elements: High-precision steel balls that ensure rolling contact between the block and the rail.
