Types of HIWIN Linear Rail Blocks

Linear guide blocks are components of linear motion systems that truck along the linear rail. HIWIN manufactures several blocks suited to meet the needs of different applications.

• Figure Block: The HIWIN linear guideway blocks type F is a square block design that provides four-way shear load capacities when used with an equal-square guideway. It features a separate fracture and is self-contained through circular tubing to retain its lubricating oil.
• Flanged Figure Block: This HIWIN block bears a similar design to the figure block guide but features an integrated flange for simple mounting. The integrated flange eliminates the need for extra machining to mount the block, thereby saving time and expenses.
• Regular Block: The standard block design of the HIWIN linear block allows it to move along an infinite number of paths. Standard blocks work properly with standard rails to provide a cost-efficient linear motion solution in situations where load capacity and rigidity are okay.
• Block with Preloaded Option: This type features a preload design that minimizes the internal clearance between the linear guideway and the block. As a result, higher rigidity and precision are provided while also enabling the block to withstand dynamic loads.
• Block with Flange: As mentioned above, HIWIN linear guide blocks with an integrated flange save on expense and time. The flange offers easy installation in locations where space is limited. HIWIN also offers optional tapped holes in blocks that provide more flexible installation choices.

Specifications and maintenance of HIWIN linear rail blocks

HIWIN linear guides specifications depend on several factors, including the type, size, and model.

• Specification of HIWIN linear guide rails:

  Types of HIWIN linear guide rails include square rails and round rails. The length varies from 100 mm to 3000 mm or more. Common sizes of square HIWIN linear guide rails are from 15 mm to 55 mm. For round rails, the diameter is usually from 12 mm to 25 mm. The heavy load capacity of the guide rails also depends on their size and length. The block can support 1500 kg of load or even more depending on the design.

• Specification of HIWIN linear rail blocks:

  HIWIN linear rail blocks have a few common types such as open type, closed type, end seal type, and middle seal type. Each type is different in dimension and characteristics. The blocks have a standard stroke length from 10 mm to 100 mm. Some HIWIN blocks have a self-lubricating option for additional protection. Heavy load blocks can support a load of more than 60 kg, while light load blocks are suitable for lighter duties.

Some HIWIN linear guides are compatible with specific sizes and models. Users must choose the combination to get the desired linear motion system. To combine an accurate fit and optimum performance, the user may need to know the following dimensional data: rail length, block number, rail profile, block dimension, and rail dimension.

Proper maintenance ensures long-lasting linear rail blocks. Lubrication is the most important step in maintaining HIWIN linear blocks and guides. It reduces wear and tear to increase the lifespan. The product is delivered with enough lubricant inside the block. If users install it in a dry or dusty place, they should investigate the need for re-lubrication after some use. They should also check the lubricant amount before starting operations.

Lubricants can be grease or oil. The type depends on the temperature and the rail block's working environment. Use a grease gun with a nozzle to lubricate the product easily. For unsealed blocks, apply grease along the entire length of the rail. Lubricate only the sliding area for sealed blocks. The ideal method is to apply grease after completing the entire setup. This way, enough grease gets distributed along the entire length of the rail and inside the block.

If the product gets dirty, clean it using a lint-free cloth. First, remove the block from the rail, then clean both parts. If dirt is stuck, a solvent can help remove it and clean the surface properly. Maintain a thin film of grease on the surface of both the rail and block to deter future dust and dirt.

Scenarios of Hiwin Linear Rail Blocks

Hiwin linear rails and blocks are used in many industries and machine-making fields.

• Machinery and Equipment that Demand Precision and High Weight Capacities: In a CNC machine, a linear guide may allow a cutting head to travel precisely in two dimensions as it cuts out a shape from a solid piece of material. Also, such machines need guides, which blocks can smoothly and precisely constrain motion along a linear path. Other machines, such as an industrial robot, use linear rails and blocks to achieve the same high-precision motion.
• Medical Imaging Systems: A medical imaging machine, like a CT or MRI scanner, needs rails and blocks to move the imaging equipment precisely as required for its diagnostic procedure. In such a scenario, a heavier linear block bearing may be required to support the scanner's weight. The motion required is often high-accuracy circular motion that takes place over a linear path.
• Robotics Applications: In robotics, linear guides and blocks are used to create robots with joints that can bear heavy loads yet move smoothly and precisely. Robots in heavy industries like automobile assembly may need to carry and assemble heavy parts. The robot will have a joint that uses rails and blocks to allow smooth and accurate motion as it moves an assembled part to its desired location.
• Medical Device and Pharmaceutical Manufacturing Equipment: A linear guide with a block is required in dispensing devices and cell culture media preparation and storage equipment. Many microfluidics applications require media to flow smoothly through narrow channels in precise small volumes. Accurately moving linear guides help promote precise motion in such systems.
• Optical Interferometers and Spectrometers: Optical measurement devices such as interferometers and spectrometers use linear guides to help position optical components precisely when making interference patterns or spectra. Such optical devices require accurate measurement and sometimes also measurement at high frequencies, for example, intervals on the order of hundreds or thousands of lines per millimeter.

How to choose

When selecting linear guideways and blocks for a particular application, it is important to ensure adequate load capacity, rigidity, running accuracy, lubrication, sealing, straightness and surface finish of the rail, mounting accuracy, material, and length of the rail.

• Load capacity

  Ensure that the load capacity of the linear blocks and guides matches the weights and forces of the equipment.

• rigidity

  Select rails with sufficient rigidity to prevent bending or deformation during operation, affecting precision.

• Running accuracy

  Choose linear guides with appropriate running accuracy (such as IT7/6) to meet the precision requirements of the equipment.

• Lubrication

  Consider the lubrication method (such as grease/oil/automatic lubrication, etc.) to ensure smooth operation and prolonged service life.

• Sealing

  Select appropriate sealing elements to prevent dust, contaminants, etc., from entering the interior and damaging it.

• Straightness and surface finish of the rail

  The straightness and surface finish accuracy of the rail directly affect the running accuracy and smoothness of the linear motion system. Choose a linear guide with excellent straightness and surface finish to ensure its precision and smooth operation.

• Mounting accuracy

  Ensure that the mounting accuracy of the linear guide matches the mounting surface of the equipment to ensure proper bonding and alignment.

• Material

  Select the appropriate material (such as carbon steel/stainless steel, etc.) according to the working environment condition to adapt to the corrosive or harsh environment.

• Length of the rail

  Choose the appropriate length of linear guide, ensure that it can provide enough travel and support for the equipment.
