The HGH Series Linear Guideway (HGH15, HGH20, HGH25, HGH30, HGH35) is an industry-standard, heavy-load linear motion system designed for extreme rigidity and precision. Featuring square-type sliding blocks with circular-arc raceways, this four-row design offers equal load ratings in all directions, making it essential for CNC routers, machine tools, and automation equipment. Available in sizes from 15mm to 65mm, we provide high-quality manufacturing, customizable OEM production (from technical drawings), and flexible B2B payment terms with fast 3–15 day delivery.
The HGH Series Linear Guide is widely recognized as a benchmark for heavy-duty linear motion. Engineered with optimized circular-arc grooves, the HGH block provides a wider contact area between the steel balls and the raceway. This design significantly enhances the load capacity and rigidity compared to standard linear guides. With an equal load rating in radial, reverse radial, and lateral directions, it perfectly absorbs installation errors while maintaining smooth, high-speed, and high-precision linear motion.
We supply the full range of heavy-duty HGH square-type blocks and corresponding rails to fit your exact machine requirements.

Machinery builders and aftermarket distributors choose the HGH series for its uncompromising performance:
4-Way Equal Load Capacity: The four-row design handles forces from top, bottom, left, and right equally well, making it highly stable during multi-axis CNC operations.
Self-Aligning Capability: Easily absorbs structural mounting errors caused by surface imperfections, dramatically reducing assembly time and cost.
Low Friction & High Speed: The optimized ball recirculation design limits friction, resulting in lower power consumption and minimal heat generation during rapid, repetitive movements.
Because of its massive load-bearing capability and high structural rigidity, the HGH series is the default choice for heavy machinery, including:
CNC routers, machining centers, and heavy-duty lathes.
Automotive manufacturing and automated tractor assembly lines.
Precision electric machines and heavy water pump mechanisms.
Agricultural machinery and industrial textile machinery.
We are structured to support global B2B supply chains, offering complete drop-in replacements for popular Taiwanese and Japanese linear guide brands.
OEM Customization: Send us your technical drawings or physical samples, and we can manufacture custom rail lengths, specific hole pitches, or apply your requested brand marking directly on the products.
Packaging: Supplied in our standard industrial packaging or customized to your specific retail/distribution requirements.
Lead Time: Normally 3–15 days for production and dispatch.
Payment Terms: Highly flexible to suit your financial processes. We accept 100% L/C at sight, 30% T/T deposit with 70% against B/L copy, 30% T/T deposit with 70% L/C at sight, Western Union, and PayPal.
Q1: What does "CA" or "CC" mean on an HGH block (e.g., HGH20CA vs. HGH20CC)?
A: "CA" indicates the standard load block length for the HGH series, while "CC" (or sometimes HA) indicates a heavy-load, extended-length block that contains more steel balls for even higher load capacities.
Q2: Are these rails interchangeable with HIWIN HG series?
A: Yes, our linear guides are manufactured to precise international standards and dimensions, making them highly compatible and interchangeable with major brands like HIWIN's HG series, perfect for aftermarket replacement and OEM assembly.
Q3: Can the rails be cut to a specific custom length?
A: Absolutely. Please provide your required overall length and the end-hole distance (E-dimension) when requesting a quote, and we will cut the rails precisely to your specifications.
Q4: Do you require drawings for OEM branding?
A: For simple brand marking on the blocks, your logo file is sufficient. For customized block designs, specialized hole spacing, or non-standard materials, technical drawings or physical samples are needed.
