Linear guide rail hgr25

Types of linear guide rail HGR25

A linear guide rail HGR 25 is a component that provides flat motion control in machinery. It gives free movement along a straight line. An HGR linear guide consists of a rail and a moving block or carriage that rides on the rail. The block typically uses recirculating ball bearings or bearing rollers to reduce friction between the sliding parts. This design allows for smooth, straight-line motion. Additional features can include self-lubricating blocks for low maintenance or lightweight aluminum rails for portable equipment.

Linear guides can be categorized into 4 main types based on their design and construction:

• Linear guide rail with block slides: This type of linear guide has a stationary rail. It allows a moving block to slide along without any additional space requirements or construction.
• Self-contained linear slides: This linear guide is preassembled, making it easy to insert into equipment or devices without building complexity into the design of the original piece of machinery. They are usually considered as a finished part.
• Miniature linear guides and slides: These types of linear guides provide the same flat motion control but on a smaller scale. This allows use in devices requiring components to be compact and not take up much space to function.
• Interchangeable linear guides and slides: This type of linear guide is made so that when it eventually wears out, it can be easily replaced by a new one of the same size and style without having to change anything else about the machine to accommodate the different part.

Specification and Maintenance

Following are the specification details corresponding with the applicable machines or devices.

• Block size: The block that carries the moving part is available in size 25 (HGR25) and size 15 (HGH15).
• Rail length: The linear slide rail is cut to the required length. This can vary from a few centimeters to several meters.
• Weight capacity: A linear guide's weight capacity depends on its size and dimensions, such as HGR25 or others. A bigger block will have a higher weight capacity. For example, an HGR25 model can bear a load of 9000N (900 Kg) with good stability.
• Movement speed: Linear rails can move components at various speeds, from sluggish to rapid, depending on the device utilizing them. A linear guide rail can handle rapid speeds of up to 4 m/s (meters/second).
• Operating temperature range: The temperature range may vary, but it is typically from minus 20 to Plus 80 degrees centigrade.
• Accuracy: Linear guides have different classes of precision, such as normal, high, and super high. High-precision rails can provide straightness and flatness of 0.02 mm/m or more excellent.
• Load ratings: Linear rails have a set load rating based on size, capacity, and configuration. Those with a higher rating are more suited for heavy-duty use in industrial contexts.
• Lubrication system: Linear rails may have automatic or manual lubrication options, such as grease ports or channels for oil distribution.

Maintenance

The linear guides can last a long time by following a few simple maintenance tips.

• Regularly clean the rails and blocks to remove debris or contaminants.
• Apply lubricant at regular intervals. This reduces wear and tear and prolongs the life of the guide rails and blocks.
• Make periodic inspections, such as looking for signs of damage or excessive play as part of routine maintenance.
• Ensure proper alignment of the linear guide components and fixation as it allows even load distribution and minimum friction.
• Replace the linear slider or rail if there is any sign of damage to maintain the functional quality of connected machines or devices.

FAQ

Q1: How to install HGR linear guide rails?

A1: First, clean the mounting surfaces. Then, put the linear guide and the slider together. The next step is to use bolts to attach them. Adjust the position, and then, test running performance after sealing or applying lubrication.

Q2: What are the features of HGR linear guides?

A2: The HGR linear guide rails possess several features. They have high load capacity, high rigidity, low friction, and smooth movement. The linear motion is stable. Meanwhile, the length is customizable to meet different applications. In addition, HGR20, HGR25, HGR30, and HGR35 are available for different weight-bearing demands. Those make the HGR linear guides suitable for a wide range of applications, such as CNC machines, automation equipment, and industrial machinery.

Q3: Do linear rails support axial loads?

A3: Linear rails are not designed to support axial loads. Applying axial loads may cause premature wear, damage, or failure of the linear motion system.

Q4: Why does the linear guide rail stuck?

A4: There are some possible reasons. Incorrect installation may lead to stuck. Debris or dirt on the rail or carriage may block the moving parts and cause stuck. If the linear rail is damaged or warped, it may affect the running performance too. Incorrect lubrication or over-lubrication may result in stuck as well.
