High Assembly Bottom Lock HGR-T Series Linear Guideway

The HGR-T series is a high-assembly linear guide rail featuring a bottom-locking mounting structure. Unlike traditional methods where screws are tightened from the top of the slider, all mounting screws are fastened from the side or diagonally from the bottom of the slider. This unique design allows the workbench or load to be directly covered and fixed onto the slider from above, without the need for screw clearance holes on the load or the use of spacers. This is particularly suitable for high-end applications where space is extremely limited, integrated design is required, or top access is impossible.

Technology

The core value of the HGR-T series lies in its revolutionary mounting method that "frees up top space and enables seamless integration."

Feature Dimensions HGR-T Series Bottom-Locking Slides Traditional locking slides (e.g. HGH-HA) Core Values
Core Positioning An innovative solution that overcomes the challenges of top-mounted installation, enabling the ultimate in compact and integrated equipment design. A universal, standard installation method suitable for most applications. Overcomes the design limitations imposed by traditional installation methods.
Installation Method Locking from the side or bottom. As the mounting screws do not penetrate the top of the slide block, the load platform can be mounted directly against the upper surface of the slide block. Secured from the top. Installation screws must be screwed in from the bottom of the load platform, or the load platform must be fitted with clearance holes. Allows the load platform to act as a ‘cover plate’ that directly encloses the slide block, simplifying the structure and reducing overall height.
Compact Design Excellent. By eliminating the need for top clearance for mounting screws, the overall height of the moving parts can be minimised, resulting in a simpler structure. Requires space for a spanner or sufficient clearance height. Enables the design of ultra-slim equipment modules and built-in slide rails.
Rigid Connection High. The screws are tightened diagonally from the lower side, generating a downward pulling force that firmly ‘presses’ the load platform against the slide’s reference surface, ensuring a large contact area and a secure connection. High. Screws are tightened vertically, ensuring a reliable connection. Offers connection rigidity equivalent to, or even superior to, traditional methods.
Sealing and Dust Protection Superior. As the top of the slide can be completely covered by the load platform, this fundamentally eliminates the risk of dust, chip accumulation and liquid dripping onto the top, providing better protection. Screw holes or gaps at the top may act as entry points for contamination. Particularly suitable for harsh environments such as cleanrooms, as well as those with high levels of dust and oil contamination.
Ease of Maintenance Note: When installing or removing the load platform, it may be necessary to operate from the side of the equipment, which imposes certain space requirements. Direct operation from above is generally more intuitive and convenient. In specific configurations, maintenance accessibility can be addressed through design.

Main Technical Parameters and Design
1. Locking Structure Principle:  Uses a side-angled hole or bottom countersunk hole design, secured with internal hexagon flat-head screws. During installation, the screw heads are recessed into the slider body and do not protrude.
2. Performance Retention: As a high-assembly type, it fully inherits the high rigidity, high load capacity, and high precision performance of high-assembly guide rails, only changing the mounting interface.
3. Installation Steps:
First, fix the guide rail to the machine bed.
Align and place the load platform on the slider.
From the side or through pre-drilled holes in the load platform, use an extended hex wrench to diagonally insert into the locking holes of the slider to complete the fastening.

Applications
The High Assembly Bottom Lock HGR-T Series Linear Guideway is the preferred choice for the following structurally innovative and space-optimized equipment:
High-speed and high-precision machine tools: Tool magazine movement mechanisms of vertical machining centers, worktables of precision grinding machines, enabling an integrated design without top protrusions.
Semiconductor and panel equipment: In-chamber manipulators of lithography machines and OLED evaporation machines, requiring no exposed screws in vacuum or clean environments.
Medical and laboratory equipment: Motion platforms of automated analyzers and cell culture equipment, facilitating cleaning and preventing contamination.
Industrial robots: Slider for the seventh axis (ground rail) of robots, allowing the robot base to be directly mounted as the load platform without the need for additional adapter plates.

The High Assembly Bottom Lock HGR-T Series Linear Guideway is not just an improvement of a component, but a liberation of design thinking. It frees engineers from the traditional constraint of "having to leave top clearance for screws," opening up new possibilities for more compact, integrated, and streamlined equipment designs. Choosing the HGR-T series means you are pursuing the ultimate optimization and innovation in equipment design, striving to create cutting-edge products that are exemplary in performance, reliability, and space utilization. It represents a significant step forward in linear motion technology to meet the demands of future high-end equipment.
