HIWIN linear blocks are the parts that permit the linear motion of a linear guideway. HIWIN linear blocks fit over the sharpened rods of the linear guideway, which might sometimes be referred to as a rail. These blocks contain recirculating ball bearings that glide smoothly along the guideway. An example is the HIWIN linear block HGW55CC.
Typically, linear motion blocks are machined from carbon steel, stainless steel, or aluminum alloy. The blocks might be open, which usually showcases one of the main features of linear motion systems, the recirculating ball bearings, or they might be closed. Closed blocks are typically preferred when it is critical for the system to be protected from external contaminants. The same reasoning might be used to apply for open blocks in systems that require high-speed functionality.
In terms of load capacities, linear blocks are usually comprised of a single row, double row, or four-point contact. Single-row blocks can support loads in high-accuracy applications, while double-row blocks are preferred for high-stability and large-load applications. Sufficiently preloaded linear blocks can also be used to achieve a higher stiffness."; They might also be comprised of angular contact ball bearing arrangements. Blocks would typically be angular regardless of the load they are supporting if they are required to have a high rigidity and a high load-carrying capacity.
HIWIN linear blocks also make room for attached parts in machinery with flanged structures. This is referred to as the linear flange block. Another configuration is the linear block slider, which is typically used in conjunction with pinch roller linear actuators and guided by a single rod.
Block size:
The block size of the HIWIN linear block consists of small blocks or balls that fit within a rail or guideway. They provide support and enable smooth movement along the rail. In this context, the HIWIN linear block HGW55CC has an extraordinary HGW55 block size.
Load capacity:
Because of the larger block size, HGW55 blocks support higher loads than smaller blocks. The load rating for linear motion blocks is different for each type of linear motion rail HIWIN makes. For the HGW55CC model specifically, its maximum load is approximately 13,417N for calculating the basic static load rating.
Guideway Compatibility:
The HIWIN linear block is compatible with particular guideways or rails manufactured by HIWIN. This means that the block is specifically intended to work seamlessly with the guideways or rails produced by the same manufacturer.
Seals:
The HIWIN linear block features seals that provide protection against dust and contaminants. These seals help to extend the lifespan and performance of the linear block by preventing the entry of foreign particles that could potentially damage the internal components.
Linear guide blocks should be properly maintained to ensure smooth movement, extend service life, and operate safely. The following maintenance methods are for users to refer to.
Lubrication:
Regularly lubricate the linear guide block to ensure sufficient lubricant supply. Choose the proper lubricant as per the linear guideblock material and operating environment, and apply it evenly to reduce friction and wear.
Cleaning:
Regularly clean the linear guide blocks to remove surface dust, dirt, and other contaminants. Use non-corrosive cleaning agents and soft cloths or brushes to wipe or wash gently, avoiding damage to the block surface. Pay attention to cleaning the deep groove and path to ensure smooth lubricant circulation.
Check and adjust:
Periodically inspect the linear guide rails and blocks for signs of wear, damage, or looseness. If any abnormalities are detected, perform adjustments or repairs promptly to prevent further deterioration and ensure stable operation.
Prevent interference:
Keep the surrounding environment of the linear guide block clean, preventing external contaminants such as dust, water, and oil from interfering with the block's normal operation. Maintain a suitable operating environment and, if necessary, employ protective measures to extend the block's lifespan.
The HIWIN linear block HGW55CC plays a pivotal role in various industries and sectors, from manufacturing to medical facilities. Its ability to facilitate precise motion control and automation systems has made it an indispensable tool across different applications. One prominent sector where linear blocks are used is the manufacturing industry, which encompasses various linear motion systems. These include CNC machines, where the HIWIN linear block aids cutters in making precise and controlled motions to achieve the desired shape on products. It is also used in assembly lines for accurate placement and positioning of components during assembly.
In the robotics industry, HIWIN linear blocks are integral components in automated guided vehicles (AGVs) and robotic arms. AGVs rely on linear blocks to help them move along predetermined pathways with precision. Manufacturing robots use linear blocks to enable different arms to move smoothly and accurately when handling, assembling, or welding tasks.
Medical equipment also uses linear blocks to help achieve precise motions. For example, in MRI and CT machines, linear blocks help the imaging components move smoothly and accurately to capture clear images of the patient's body. Linear motion blocks with HIWIN's proprietary anti-rust technology are used in humid and harsh environments, such as medical cleanrooms.
In the aerospace industry, linear blocks control and move various systems in aircraft. They are used in cabin doors, landing gears, and wing flaps. Linear motion blocks also help increase the jet engines' efficiency by enabling smooth and precise movements of components.
HIWIN linear blocks can also be used dynamically in the entertainment industry. They are integral to constructing theme parks and high-end theaters. In theme parks, linear motion blocks are the backbone of roller coasters, helping them achieve complex and smooth movements to provide riders with a thrilling experience. They also help properly establish and position props in high-end theaters. Sports equipment uses the HIWIN linear blocks to help achieve athletes' training and sports skills.
When selecting HIWIN linear blocks, buyers should consider a variety of parameters to ensure that they are suitable for their particular application requirements.
Load capacity and weight:
Firstly, the maximum weights that will be moved along with the linear motion system should be calculated. This includes both the weight of any attached load as well as the weight of any other components that may be sliding over the linear block. With this total sliding mass determined, a suitable linear block system can be chosen with an adequate load rating to support its entire weight. It is essential to ensure that the selected block can handle the fully loaded weight without experiencing any undue stress or deterioration in performance during regular use. By properly matching the load capacity of the linear block to the complete sliding mass, reliable operation of the entire motion system can be maintained.
Working environment:
HIWIN linear blocks are appropriate for deployment in various kinds of environmental contexts. To suit the working environment, it is essential to choose the correct material and surface treatment. For instance, block slides are appropriate for use in a vacuum environment because they lack lubrication. Furthermore, those with stronger seals or higher-quality greases are generally more suitable for damp settings. Conversely, blocks that are suited for high-temperature situations may possess heat-resistant lubricants and components. The surface treatment of the rail can increase its resistance to corrosion, making it more appropriate for deployment in coastal areas.
Compatible design elements:
Consider the other components of the system that the linear block must connect with, including any guided rails it needs to slide along. In particular, the linear rail blocks that are selected must allow for coherent, efficient compatibility with the linear rails and all other existing elements in the assembly.
Q1: Are all linear blocks the same size?
A1: No, linear blocks come in different sizes, such as HGW15, HGW20, etc. The size is determined by the amount of load the linear block will need to hold and the distance it needs to travel.
Q2: What are the differences between linear blocks and linear guides?
A2: Linear blocks and linear guides are both components that provide linear motion. However, the Hiwin linear guideway system involves multiple linear guides that are often composed of a rail and several blocks. Meanwhile, a single linear block can function independently without the support of a linear guide.
Q3: Are linear blocks easy to replace?
A3: Yes, with good maintenance, Hiwin blocks can be easily replaced when they become worn or damaged.
