Description

Linear Block, Sliding Block

Model Series: HGH/HGW

• Designed for use with linear rails.
• HGH refers to a square block linear rail, while HGW denotes a wide (flanged) block type.
• Linear 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 contain ball bearings that facilitate movement.
• They enable smooth, rapid, and convenient linear motion along the rail.
• The HGH series features square-profile linear blocks, while the HGW series offers wide, flanged block profiles.

Features: Linear Blocks (HGH and HGW Series)

• High precision, smooth operation, superior wear resistance, and low noise levels.
• Advanced manufacturing technology ensures precise products with high hardness and durability.
• High bearing capacity and low friction coefficient.
• Widely applicable in CNC machine tools, machining centers, electronics, automation machinery, textile machinery, automotive woodworking machinery, printing machinery, and more.

Linear Block: HGH

Linear Block: HGW

Installation: Correct Installation Procedure for Linear Blocks

1. Position the slider parallel to the guide rail.
2. Gently slide the block onto the guide rail.
3. Continue sliding the block along the guide rail until fully seated.
4. Installation is complete. Ensure the retaining balls remain in place.

During installation, do not remove the plastic dummy rails within the slider prematurely. Doing so can cause the internal balls to dislodge, preventing proper installation and operation. When disassembling, ensure the dummy rail is used to retain the balls and prevent their loss.

Installation Tip: Using a guide rail without dummy rails, especially those made of #55 steel with sharp cutting edges, can lead to the premature ejection of balls from the ball grooves.

The HGW and HGH linear block types exhibit distinct differences in their design and application:

Structure and Design
HGW (Heavy Load Wide Linear Guide)

• Wider Profile: Features a broader design for both the rail and block, enhancing stability and weight distribution.
• Heavy Load Capacity: Engineered to support heavier loads, offering superior load-bearing capabilities compared to SBR (Support Rail Guide) blocks.

HGH (High-precision Linear Guide)

• Standard Profile: Characterized by a rectangular rail with integrated ball or roller elements.
• High Precision: Delivers exceptional accuracy in linear motion, making it suitable for applications demanding high precision.

Load Capacity and Stability

• HGW: Provides higher load capacity and stability, ideal for heavy-duty applications. The wider rail width contributes to increased movement stability and reduced vibration or deflection.
• HGH: Offers good load capacity, though generally less than HGW, with a primary focus on movement accuracy. Suitable for applications requiring high precision rather than extreme load bearing.

Applications

• HGW: Employed in applications requiring significant load capacity and high stability, such as heavy industrial machinery, large CNC machines, and robust equipment.
• HGH: Used in applications demanding high precision and smooth motion, including CNC machines, 3D printers, and precision manufacturing equipment.

Summary

• HGW: Recommended for applications prioritizing heavy load capacity and high stability.
• HGH: Recommended for applications prioritizing high precision and smooth motion.

The selection between HGW and HGH depends on specific application requirements. HGW is the preferred choice for enhanced stability and load capacity, while HGH is more suitable when precision is the primary concern.
