Description

Linear Block, Sliding Block for Linear Rails

Model Series: HGH/HGW

• Designed for use with linear rails.
• The HGH series features a square block profile, while the HGW series offers a wider, flanged block type.
• Sliding blocks are utilized with linear rails in various industrial applications, including CNC machinery systems. They serve as load-bearing components on the linear rail.
• Constructed from steel or aluminum, these blocks incorporate internal bearings for smooth linear motion.
• They enable convenient and rapid bidirectional movement along the rail.
• The HGH model is a square-profile block, and the HGW model is a wider, flanged block.

Linear Rail

Correct Installation Procedure for Linear Blocks

1. Position the slider parallel to the linear rail.
2. Gently slide the block onto the linear rail.
3. The slider will fully engage with the linear rail.
4. Installation is complete. Ensure the retaining balls are not dislodged.

 

 
During installation, do not remove the plastic dummy rails from the slider prior to mounting. Failure to do so may result in the loss of retaining balls during assembly, preventing proper installation and function. When disassembling, use the dummy rails to facilitate removal and prevent ball spillage.

Installation Tips:

If not using dummy rails, the sharp edges of rails made from No. 55 steel can easily eject the balls from the ball grooves.

Comparison of HGW and HGH Linear Blocks:

Structural Design

HGW (Heavy Load Wide Linear Guide)

• Wider Profile: Engineered with a broader rail and block for enhanced stability and superior load distribution.
• Heavy Load Capacity: Designed to support significant loads, offering greater capacity than SBR (Support Rail Guide) blocks.

HGH (High-precision Linear Guide)

• Standard Profile: Features a square rail with internal ball or roller bearings.
• High Precision: Delivers exceptional positional accuracy, ideal for applications demanding stringent tolerances.

Load Capacity and Stability

• HGW: Possesses higher load-bearing capabilities than HGH, making it suitable for applications with heavy loads and requiring excellent weight distribution. The wider rail enhances operational stability and mitigates vibration and deflection.
• HGH: Offers good load capacity, though less than HGW, with a primary focus on high positional accuracy. It is well-suited for precision-critical tasks not involving extremely heavy loads.

Applications

• HGW: Recommended for heavy-duty applications demanding high stability, such as heavy industrial machinery, large-format CNC machines, and robust equipment.
• HGH: Ideal for applications requiring high precision and smooth motion, including CNC machines, 3D printers, and manufacturing equipment where accuracy is paramount.

Summary

• HGW: Optimal for applications prioritizing heavy load capacity and high stability.
• HGH: Best suited for applications demanding superior precision and smooth movement.

The selection depends on specific project requirements. For enhanced stability and load-bearing performance, HGW is the preferred choice, while HGH is more appropriate when precision is the primary consideration.
