The SBR45SL is a sophisticated linear guideway offered by SBC, designed to meet the demands of precise linear motion systems. Its mounting dimensions are characterized by H of 70mm, W of 86mm, and L of 147.3mm, which are essential for accurately planning the installation space. The mounting tap hole features an M10 thread specification, ensuring a secure attachment during installation. For the block, the length L1 is 101.3mm. The height tolerance (T±) along with other structural dimensions like K and T1 contribute to the smooth and stable operation of the guideway. The width of the rail part (F) is 50mm. The bolt holes have a diameter (d) of 14mm, a depth (h) of 20mm, and a spacing (G) of 19mm, facilitating efficient assembly. The maximum length of the rail can reach up to 4000mm, making it suitable for a wide array of applications that require extended linear travel. It has a robust basic dynamic load rating (C) of 95kN, indicating its excellent capacity to handle dynamic loads during operation. The basic static load rating (Co) is 184kN, ensuring stability when the guideway is at rest. In terms of permissible static moment, the longitudinal torque under static load (Mto) is 2.61kN - m, and under dynamic load (Mt) is 1.53kN - m. The transverse torque under static load (MLO) is 5.07kN - m, and under dynamic load (ML) is 2.97kN - m. The rail has a mass of 10.7kg per meter, an important consideration for overall system design and weight - related calculations.
