The SBR45FL linear guideway from SBC is a high - quality product designed for precise linear motion applications. Its mounting dimensions are as follows: H is 60mm, W is 120mm, and L is 147.3mm, which are essential for determining the installation space. The mounting tap hole has a thread specification of M12, ensuring a secure connection. For the block dimensions, the length (L1) is 101.3mm. The height tolerance (T±) and other structural dimensions like K, T1 contribute to its stable operation. The rail has a width (F) of 50mm. The bolt holes have a diameter (d) and depth (h), and the hole spacing (G) is designed for proper assembly. The maximum length of the rail can reach 4000mm, making it suitable for a wide range of applications that require extended linear travel. It has a basic dynamic load rating (C) of 95kN, enabling it to handle significant loads during movement. 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 block of this guideway weighs 3.3kg, and the rail has a mass of 10.7kg per meter, which are important factors for system design and weight calculations
