The SBMWL12 is a linear guideway model from SBC, designed to meet diverse linear - motion requirements. Mounting Dimensions: With a mounting height (H) of 14mm, width (W) of 40mm, and length (L) of 59.5mm, it provides specific installation - space requirements. The mounting tap hole has a thread specification of M3, which ensures a secure connection during installation. Dimension B is 4mm and J is 28mm, contributing to the overall installation - structure layout. Block Dimensions: The block length (L1) is 42mm. Other dimensions like T (5mm), K (8.5mm), and T1 (2.4mm) are carefully configured for smooth operation on the rail. The greasing hole has a diameter of φ1mm for easy lubrication maintenance. The outer - shape dimensions of the block, such as W1 (24mm), W2 (8mm), and H1 (5mm), are optimized for compatibility with other components in the system. Rail Dimensions: The width of the rail part (F) is not indicated in the table. The bolt holes on the rail have a diameter (d) of 5mm, a depth (h) of 4.5mm, and a spacing (G) of 15mm, facilitating a firm attachment to the supporting structure. Maximum Rail Length: The maximum length of the rail (LO) is 1190mm, making it suitable for a wide range of applications that require linear movement over a relatively long distance. Load - Bearing Capacity: It has a robust basic dynamic load rating (C) of 5.96kN, demonstrating its ability to handle dynamic loads during operation. The basic static load rating (Co) is 9.21kN, ensuring stability when the guideway is stationary. Regarding the permissible static moment, the longitudinal torque under static load (Mto) is 89.18kN - m, and under dynamic load (Mt) is 46.35kN - m. The transverse torque under static load (MLO) is 52.82kN - m, and under dynamic load (ML) is 47.63kN - m. Mass: The rail has a mass of 1.42kg per meter, which is a crucial parameter for system designers when calculating the overall weight of the linear - motion system and assessing its impact on the mechanical structure's performance and energy consumption.
