Description

Linear Block, Sliding Block

Model Series HGH/HGW

• Designed for use with linear rails.
• HGH represents a square block linear rail, while HGW is a wide block type (with integrated wings).
• Linear blocks are utilized with linear rails in various industrial applications, including CNC machinery systems, serving as the load-bearing component on the rail.
• Manufactured from steel or aluminum, these blocks incorporate internal ball bearings for drive mechanisms.
• They enable smooth and rapid reciprocal movement along the linear rail.
• The HGH series features a square-shaped linear block, whereas the HGW series offers a wide, winged rectangular block profile.

Correct Installation Procedure for Linear Blocks

1. Align the slider parallel to the guide rail.
2. Gently slide the block onto the guide rail.
3. Ensure the slider smoothly enters the guide rail.
4. Installation is complete; avoid dislodging the steel balls.

During installation, do not remove the protective plastic guide rails from the slider beforehand, as this may cause the internal steel balls to dislodge, preventing proper installation and operation. When disassembling, utilize the guide rails to retain the balls.
Installation tips:
If the guide rail lacks protective features, the sharp edges of the rail (e.g., No. 55 steel) can potentially eject the balls from the ball grooves.

The HGH and HGW series linear blocks exhibit distinct differences in design and application:

Structural Design
HGW (Heavy Load Wide Linear Guide)

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

HGH (High-precision Linear Guide)

• Standard Structure: Characterized by a rectangular profile with integrated ball or roller bearings.
• High Precision: Delivers exceptional positional accuracy, ideal for applications demanding stringent tolerances.

Load Capacity and Stability

• HGW: Possesses higher load capacity than HGH, making it suitable for applications requiring significant weight support and optimized load distribution. The wider rail contributes to improved stability and reduced vibration or deflection during movement.
• HGH: Offers good load capacity but is generally lower than HGW, prioritizing high-precision movement over extreme load handling. It is well-suited for applications requiring accuracy without excessive weight demands.

Application Scenarios

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

Summary:

• HGW: Best suited for applications prioritizing heavy load capacity and high stability.
• HGH: Optimal for applications requiring high precision and smooth operational characteristics.

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