Description

Linear Block, Sliding Block

Model: HGH/HGW

• Must be used in conjunction with a linear rail.  
• HGH refers to a square block linear rail, while HGW is a wide (flanged) block type. 
• Linear Sliding Blocks are utilized with linear rails in various industries, including CNC machinery. They serve as load-bearing components on the linear rail.
• Manufactured from steel or aluminum, these blocks contain ball bearings to facilitate movement.
• They enable smooth back-and-forth motion along the rail, facilitating convenient and rapid travel.
• The HGH model is a square-shaped linear block, while the HGW model is a wide (flanged) rectangular block.

Features: Linear Block (HGH and HGW)

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

Specification: Linear Block (HGH and HGW)

Linear Block: HGH

Linear Block: HGW

Installation: Correct Installation Procedure for Linear Sliding Blocks

1. Place the slider parallel to the guide rail.
2. Gently push the slider onto the guide rail.
3. Slide the slider onto the guide rail.
4. Installation is complete; ensure the steel ball retainer is not dislodged.

During installation, do not remove the plastic dummy rails within the slider prematurely. Failure to do so may result in the steel balls within the slider dislodging during assembly, preventing proper installation and function. When disassembling, use the dummy rails to assist in the process and prevent ball loss.

Installation Tips: 

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

Structural and Design Differences:

HGW (Heavy Load Wide Linear Guide)

• Wide Structure: Features a wider rail and block design, enhancing stability and weight distribution.
• Load Capacity: Designed 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 square rail profile containing ball or roller elements.
• High Precision: Provides elevated accuracy in movement, suitable for applications demanding stringent tolerances.

Load Capacity and Stability:

• HGW: Excels in load capacity and stability due to its wider profile, making it ideal for heavy-duty applications. The increased rail width contributes to movement stability and reduced vibration or deflection.
• HGH: Offers good load capacity, though generally less than HGW, with a primary focus on movement precision. It is well-suited for applications requiring high accuracy without extreme load demands.

Applications:

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

Summary:

• HGW: Optimal for tasks demanding high load capacity and superior stability.
• HGH: Ideal for applications requiring high precision and smooth, fluid movement.

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