High Assembly HGH-CA/HA Series Linear Guideway

The HGH-CA/HA series are high-assembly (high-profile) ball-type linear guideways. High assembly refers to the relatively greater height of the slider, which provides greater load moment capacity and higher rigidity. This series features a four-way equal load design, offering excellent load-bearing capacity in radial, anti-radial, and lateral directions. Precise manufacturing processes ensure high operating accuracy, smoothness, and long service life, meeting the demands of most demanding industrial applications.

Technology

Key Features and Advantages

Performance characteristics	HGH-CA/HA Series High-Assembly Guide Rails	Low-profile guide rails (for comparison)	Core Values
Structural rigidity	Extremely high. The raised slider structure provides a greater torque-carrying span and offers exceptional resistance to overturning (torque resistance), with minimal deformation under off-centre or cantilevered loads.	Generally suitable for applications with uniform loads and low torque.	Provides a robust motion platform for complex applications involving high dynamics and high precision.
Load capacity	High. The ball circulation system is optimised, featuring a large number of balls, resulting in rated static and dynamic load capacities far exceeding those of low-assembly models of the same specification.	Medium.	Enables more compact equipment design or higher load capacities within the same space.
Operational accuracy	High. Available in multiple precision grades, including Standard (N), High (H) and Precision (P). The guide rails are precision-ground to ensure excellent straightness.	Primarily standard precision.	Forms the foundation for achieving high positioning accuracy and repeatability.
Ease of installation	The ‘high-assembly’ design simplifies installation. It is relatively tolerant of the flatness and levelness of the mounting surface, making it easier to achieve optimal operating conditions.	More sensitive to the accuracy of the mounting surface.	Reduces equipment assembly complexity and commissioning time, whilst enhancing reliability.
Model classification	CA Type: Flanged carriage, side-mounted, saving installation height space. HA Type: Square-shaped slider, top-mounted, offering secure and straightforward installation.	Typically a mainstream mounting configuration.	Offers flexible mounting options to suit different structural designs.

Main Technical Parameters and Selection Guide
1. Accuracy Grade: Typically offers multiple options from standard grade (N) to ultra-precision grade (SP), meeting different needs from general automation to ultra-precision machine tools.
2. Preload Grade: Offers options of no preload (C0), light preload (C1), medium preload (C2), and heavy preload (C3). Higher preload results in higher rigidity, but also slightly increases friction and temperature rise.
3. Sealing and Lubrication:
End seals: Standard configuration, effectively preventing dust ingress.
Bottom seals: Available on some models, providing bottom protection.
Grease nipple: Convenient for daily maintenance and lubrication.
4. Selection Points:
Confirm dimensions: Select the guideway width (e.g., HGH15, HGH20, HGH30, etc.) based on load, torque, and space.
Select model: Choose CA (flange type) or HA (square type) slider based on installation space and method.
Determine accuracy and preload: Select the accuracy grade and preload grade based on motion accuracy and rigidity requirements.

Applications
The High Assembly HGH-CA/HA Series Linear Guideway, with its comprehensive and balanced superior performance, is widely used in:
