The NSK DH series linear guide block is a linear motion component that travels on guide rails to allow smooth and precise motion in industrial machines and equipment. It is used in applications requiring high rigidity, repeatability and load capacity, such as machining centers, industrial robots and automation systems. MR Accesorios Industriales sells this series in different sizes to suit every need.
The DH series designation is read with the letters identifying the family and a number indicating the size. For example, DH15BN, DH20BN and DH25BN correspond to blocks of different sizes, where the number relates to the rail width or load capacity. The BN suffix indicates specific construction features, such as the type of sealing or preload. To select the right block, it is essential to know the rail dimensions and the operating conditions.
These blocks are used in industries such as automotive, metalworking, food and pharmaceutical, in applications ranging from coordinate tables to gantry loaders. In Argentina, they are common in machine tools, packaging equipment and handling systems. Their design allows linear motion with low friction and high precision, making them ideal for processes that demand repeatability and long service life.
To select the right block, take into account the load capacity, required rigidity, operating speed and environmental conditions. It is important to verify proper lubrication and sealing to protect against contaminants. Mounting must be done on flat, aligned surfaces, following the manufacturer's recommendations to avoid incorrect loads. Preload and clearance also influence performance and durability.
NSK DH series blocks can be interchangeable with those from other manufacturers that follow similar standards, but it is always advisable to verify the critical dimensions and load capacities before replacing a component. MR Accesorios Industriales can advise you on compatibility and source the exact part you need.
