Description

Linear Block, Sliding Block

Model Series: HGH/HGW

• Designed for use with linear rails.
• HGH denotes a square profile linear rail block, while HGW is a wide (flanged) profile block type.
• Linear 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 incorporate internal bearings for smooth motion.
• They facilitate easy and rapid linear movement along the rail.
• The HGH series features a standard square profile, whereas the HGW series offers a wider, flanged profile.

Features of 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 load-bearing capacity and low friction.
• Widely applied in CNC machine tools, machining centers, electronics, automation machinery, textile machinery, automotive and woodworking machinery, printing machinery, and more.

Linear Rail

Installation: Correct Procedure for Linear Blocks

1. Place the slider parallel to the guide rail.
2. Gently push the slider onto the guide rail.
3. The slider should slide smoothly into the guide rail.
4. Installation is complete; ensure no steel balls are dislodged.

During installation, do not remove the protective plastic guide rails from the slider beforehand, as this can cause the internal steel balls to dislodge, preventing proper installation and function. When disassembling, use the protective rails to prevent ball loss.

Installation Tips:

If not using with protective rails, the sharp edges of guide rails made of No. 55 steel can eject the balls from the ball groove.

The HGW and HGH series linear blocks differ in several aspects based on their intended applications and characteristics:

Structure and Design
HGW (Heavy Load Wide Linear Guide)

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

HGH (High-precision Linear Guide)

• Standard Structure: Characterized by a square profile rail with internal ball or roller bearings.
• High Precision: Provides high accuracy in motion, suitable for applications demanding stringent tolerances.

Load Capacity and Stability

• HGW: Offers higher load capacity and stability than HGH, ideal for heavy-duty applications requiring robust support and minimized vibration or deflection due to its wider profile.
• HGH: Provides good load capacity, though less than HGW, prioritizing motion accuracy for applications with moderate load requirements.

Applications

• HGW: Used in applications demanding high load capacity and superior stability, such as heavy industrial machinery, large CNC machines, and other equipment requiring exceptional durability.
• HGH: Utilized in applications requiring high precision and smooth movement, including CNC machines, 3D printers, and precision manufacturing equipment.

Summary

• HGW: Best suited for applications requiring high load capacity and maximum stability.
• HGH: Ideal for applications prioritizing high precision and smooth linear motion.

The selection between HGW and HGH depends on the specific requirements of the application. For enhanced stability and load-bearing capabilities, the HGW series is recommended. For applications where precision is paramount, the HGH series is the more appropriate choice.
