Description

Linear Block, Sliding Block

Model Series HGH/HGW

• Designed for use with linear rails.
• HGH denotes a square block type, while HGW is a wide (flanged) block type.
• The sliding block is utilized with linear rails in various industrial applications, including CNC machinery. It serves as a load-bearing component on the linear rail.
• Constructed from steel or aluminum, featuring ball bearings for locomotion.
• Enables smooth, rapid, and convenient linear motion along the rail.
• The HGH model is a square-shaped linear block, whereas the HGW model is a wide, flanged block.

Linear Rail

Installation: Correct Procedure for Linear Blocks

1. Align the slider parallel to the guide rail.
2. Gently insert the slider into the guide rail.
3. Slide the slider fully into the guide rail.
4. Installation is complete; ensure the retaining balls remain in place.

During installation, do not remove the temporary plastic rails within the slider. Doing so can cause the internal retaining balls to dislodge, preventing proper installation and function. When disassembling, use the temporary rails to secure the balls and prevent their loss.

Installation Tips:

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

Linear blocks of the HGH and HGW types differ in several aspects concerning their application and properties:

Structural Design

HGW (Heavy Load Wide Linear Guide)

• Wide Profile: Features a wider rail and block design, enhancing stability and load distribution.
• Robust Load Capacity: Engineered for heavy-duty applications, offering superior load-bearing capabilities compared to standard SBR (Support Rail Guide) blocks.

HGH (High-precision Linear Guide)

• Standard Profile: Characterized by a square rail profile containing internal ball or roller bearings.
• High Accuracy: Delivers exceptional positional accuracy, making it suitable for applications demanding high precision.

Load Capacity and Stability

• HGW: Optimized for higher load capacities and superior stability. The wider rail design contributes to reduced vibration and deflection during operation, making it ideal for heavy-duty tasks.
• HGH: Provides good load capacity, though generally less than HGW. Its primary advantage lies in high-precision linear movement, making it suitable for applications where accuracy is paramount and extreme loads are not the primary concern.

Applications

• HGW: Recommended for heavy load and high stability requirements, such as in heavy industrial machinery, large-scale CNC machines, and other robust equipment.
• HGH: Suited for applications demanding high precision and smooth motion, including CNC machines, 3D printers, and manufacturing equipment where precision is critical.

Summary

• HGW: Best suited for applications requiring high load capacity and enhanced stability.
• HGH: Ideal for applications prioritizing high precision and smooth, fluid motion.

The selection between HGH and HGW depends on the specific requirements of the application. For applications demanding high stability and significant load-bearing capabilities, HGW is the preferred choice. Conversely, for tasks where precision and smooth movement are the primary considerations, HGH is the more appropriate option.
