Description

Linear Block, Sliding Block

Model Series: HGH/HGW

• To be used with linear rail.
• HGH is a square block linear rail, while HGW is a wide (flanged) block type.
• Linear Blocks are utilized with Linear Rails in various industrial applications, including CNC machinery. They serve as load-bearing components on the linear rail.
• Manufactured from steel or aluminum, these blocks incorporate internal ball bearings for smooth motion.
• They facilitate easy and rapid linear movement along the rail.
• The HGH series features a square profile block, while the HGW series offers a wider, flanged profile.

Features of Linear Blocks (HGH and HGW Series)

• High precision, smoothness, superior wear resistance, and low noise operation.
• Utilizes advanced manufacturing technology for precise, high-hardness, and durable products.
• Offers high bearing capacity and low friction.
• Widely applicable in CNC machine tools, machining centers, electronics, automation machinery, textile machinery, automotive woodworking machinery, printing machinery, and more.

Installation: Correct Procedure for Linear Block Installation

1. Place the slider parallel to the guide rail.
2. Gently push the slider onto the guide rail.
3. Slide the slider fully into the guide rail.
4. Installation is complete. Do not remove the retaining mechanism for the steel balls.

During installation, do not remove the plastic dummy rails from the slider in advance, as this may cause the steel balls to dislodge, preventing proper installation and operation. When disassembling, the dummy rail should be used in conjunction with the disassembly process to retain the balls.
Installation Tips:
If not using dummy rails, the sharp edges of the guide rail (made of No. 55 steel) can easily eject the balls from the ball groove.

Structural and Design Differences: HGW vs. HGH Linear Blocks

HGW (Heavy Load Wide Linear Guide)

• Wide Profile: Features a wider rail and block design, enhancing stability and load distribution.
• Heavy Load Capacity: Engineered to support higher loads compared to SBR (Support Rail Guide) linear blocks.

HGH (High-precision Linear Guide)

• Standard Profile: Characterized by a square rail with internal ball or roller bearings.
• High Precision: Delivers superior accuracy in movement, ideal for applications demanding precision.

Load Capacity and Stability Comparison

• HGW: Offers superior load-bearing capabilities, making it suitable for heavy-duty applications and providing enhanced stability with reduced vibration and deflection due to its wider design.
• HGH: Provides good load capacity, though generally less than HGW, with a primary focus on achieving high-precision linear motion. It is well-suited for applications requiring accuracy without extreme load demands.

Application Suitability

• HGW: Recommended for applications demanding high load capacity and stability, such as heavy industrial machinery, large CNC machines, and robust equipment.
• HGH: Ideal for precision-oriented applications like CNC machines, 3D printers, and manufacturing equipment where high accuracy and smooth movement are critical.

Summary

• HGW: Best suited for applications requiring heavy load support and high stability.
• HGH: Best suited for applications demanding high precision and smooth linear motion.

The selection depends on specific application requirements. For enhanced stability and load-bearing capacity, HGW is the preferred choice. For applications prioritizing precision, HGH is the more appropriate option.
