HGH Linear Motion Guide

HGH Linear Motion Guide

HGH (Square Type)
Profile: Features a high, narrow, non-flanged square design.
Mounting Interface: Equipped with four tapped (threaded) blind holes on the top surface.
Installation: Designed for "top-down" fastening; bolts are passed through the mounting plate/carriage and threaded directly into the block.
Ideal Application: Perfect for applications where lateral (width) space is constrained. The compact, non-flanged footprint allows for a narrower machine bed or enables parallel rails to be mounted in closer proximity.

Key Engineering Features of the HGH Guide

4-Way Equal Load Capacity:
The internal ball rows are arranged at a 45-degree contact angle. This geometry allows the HGH block to bear Radial (downward), Reverse-Radial (upward), and Lateral (side) loads with equal magnitude. This versatility makes it ideal for multi-axis machines requiring varied mounting orientations, such as vertical or inverted installation.

Self-Aligning Capability:
The rolling elements utilize a Face-to-Face (DF) circular-arc configuration. This design enables the block to automatically absorb minor installation errors or surface irregularities on the mounting bed. As a result, the system prevents internal binding and maintains high-precision motion even under slight misalignment.

High Rigidity:
Engineered specifically for Heavy Load applications, the HGH series offers significantly higher stiffness than miniature (MG) or low-profile (EG) guides. This structural rigidity makes it perfectly suited for demanding applications like metal cutting, heavy machining, and high-load transport systems.
