Description

Linear Block, Sliding Block

Model Series: HGH/HGW

• To be used in conjunction with linear rails.
• HGH represents a square profile linear block, while HGW is a wide profile (flanged) block type.
• Linear blocks are designed for use with linear rails in various industrial applications or CNC machinery. They serve as load-bearing components on the linear rail.
• Manufactured from steel or aluminum, incorporating internal ball bearings for linear motion.
• Facilitates smooth and rapid back-and-forth movement along the rail.
• The HGH series features a square profile, and the HGW series offers a wider profile with integrated flanges.

Features for Linear Blocks (HGH and HGW Series)

• High precision, smoothness, superior wear resistance, and low noise operation.
• Utilizes advanced manufacturing technology for precise product construction, characterized by high hardness and durability.
• Offers high load-carrying capacity and low friction characteristics.
• Widely employed in CNC machine tools, machining centers, electronics manufacturing, automation machinery, textile machinery, automotive and woodworking equipment, printing machinery, and more.

Installation Procedure

1. Place the slider parallel to the guide rail.
2. Gently push the slider onto the guide rail.
3. The slider will then slide into the guide rail.
4. Installation is complete without the steel balls disengaging from the guide.

During installation, do not remove the protective plastic rails from the slider in advance. Doing so may cause the steel balls within the slider to dislodge during assembly, preventing proper installation and functionality. When disassembling, the protective rails should be used to retain the balls.

Installation Tips:

If installation is attempted without the protective rails, the sharp edges of the guide rail (typically made from No. 55 steel) can easily eject the balls from their designated grooves.

The HGW and HGH linear block types exhibit several distinctions based on their intended applications and inherent characteristics:

Structural Design & Applications

HGW (Heavy Load Wide Linear Guide)

• Wide Profile Structure: Engineered with a broader rail and block profile, enhancing stability and load distribution.
• High Load Capacity: Designed to accommodate heavier loads compared to standard SBR (Support Rail Guide) blocks.

HGH (High-precision Linear Guide)

• Standard Profile Structure: Characterized by a square rail profile containing either ball or roller bearings.
• High Precision: Delivers superior positional accuracy, making it suitable for applications demanding high accuracy.

Load Capacity and Stability

• HGW: Offers superior load-bearing capabilities and enhanced stability due to its wider design. This makes it ideal for heavy-duty applications requiring reduced vibration and deflection.
• HGH: Provides good load capacity, though generally less than HGW. It prioritizes movement precision, suitable for applications requiring high accuracy where extreme loads are not the primary concern.

Use Cases

• HGW: Recommended for applications demanding high load capacity and stability, such as heavy industrial machinery, large CNC systems, and robust equipment.
• HGH: Best suited for applications requiring high precision and smooth motion, including CNC machines, 3D printers, and precision manufacturing equipment.

Summary

• HGW: Optimized for applications requiring heavy load support and high stability.
• HGH: Optimized for applications prioritizing high precision and smooth, accurate movement.

The selection between HGW and HGH should be based on the specific demands of the application. For superior stability and heavy load handling, the HGW is the preferred choice. For applications where precision and smooth motion are paramount, the HGH is more appropriate.
