This is the SBM9+456L lightweight miniature linear guide way. It is designed with a ball wire type, which is known for its smooth operation and relatively simple structure. 1. Dimensions The height when the rail is combined with the block is 10mm. This compact height makes it suitable for applications where space is limited, allowing for easy integration into various machinery or equipment with height - restricted spaces. The width of the block is 20mm, and its length is 30.3mm. These dimensions ensure stable movement along the rail and proper load - distribution. The rail width is 9mm, which is optimized to support the block's motion and provide a secure guiding structure. The block upper surface fastening dimension is 15mm in width and 10mm in length, facilitating secure attachment to other components within the mechanical system. The length of the track rail is 456mm, which is an ideal length for applications that require linear movement over this specific distance. 2. Installation - related Dimensions The rail hole pitch is 20mm, and the rail hole size is designed to use an M3 bolt. These specifications enable straightforward and reliable installation of the rail to the supporting structure. The G value, which represents the distance from the end of the rail to the first hole, is 11mm at one end and 5mm at the other end. The pitch of the rail is configured as 11 + (20 X 22 times) + 5, providing a specific pattern for installation that ensures even distribution of forces and proper alignment during the setup process. This SBM9+456L linear guide way is an excellent choice for applications in miniature or space - constrained mechanical systems, such as in some precision - oriented electronic devices, small - scale automated machinery, or other equipment where lightweight and compact linear motion solutions are required. Its precise dimensions and well - thought - out design features contribute to its reliability and performance in such applications.
