Description

Linear Block, Sliding Block

Model Series: HGH/HGW

• Must be used in conjunction with a linear rail.
• The HGH series features a square block linear rail, while the HGW series is a wide (flanged) block type.
• Sliding blocks are utilized with linear rails in various industrial applications, including CNC machinery, serving as the load-bearing component on the rail.
• Constructed from steel or aluminum, these blocks contain internal ball bearings for actuation.
• They facilitate smooth, rapid, and reciprocating linear motion along the rail.
• The HGH model is a square linear sliding block, whereas the HGW model is a wide rectangular block with flanges.

Features of Linear Blocks (HGH and HGW Series)

• High precision, smoothness, excellent wear resistance, and low noise operation.
• Advanced manufacturing technology ensures precise products with high hardness and durability.
• Offers high load-bearing capacity and minimal friction.
• Widely implemented in CNC machine tools, machining centers, electronics, automation machinery, textile machinery, automotive woodworking machinery, printing machinery, and more.

Installation: Correct Installation Procedure for Linear Sliding Blocks

1. Align the slider parallel to the guide rail.
2. Gently insert the slider into the guide rail.
3. Slide the slider along the guide rail.
4. Installation is complete. Ensure no steel balls are lost during the process.

During installation, do not remove the protective plastic rails from the slider in advance, as this can lead to the loss of internal steel balls, preventing normal installation and operation. When disassembling, use the protective rails to prevent ball ejection.

Installation Tips:

If the guide rail (made of No. 55 steel) is not used with the protective false rails, the sharp edges at the corners of the rail can easily eject the balls from the ball grooves.

Linear blocks of type HGW and HGH differ in several aspects concerning their application and characteristics:

Structure and Design

HGW (Heavy Load Wide Linear Guide)

• Wide Structure: Designed with wider rails and blocks to enhance stability and weight 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: Features a rectangular profile containing internal ball or roller elements.
• High Precision: Provides highly accurate movement, suitable for applications demanding exceptional accuracy.

Load Capacity and Stability

• HGW: Possesses higher load capacity than HGH, making it ideal for tasks requiring substantial load support and improved weight distribution. The wider rail enhances operational stability and minimizes vibration and deflection.
• HGH: Offers good load capacity, though less than HGW, prioritizing movement precision. It is well-suited for applications requiring high accuracy but not excessive load conditions.

Applications

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

Summary

• HGW: Recommended for applications requiring high load capacity and superior stability.
• HGH: Recommended for applications demanding high precision and smooth movement.

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