The Bosch Rexroth SEM-E-C 40X20RX6-3 (R151247075) is an adjustable preload single ball screw nut designed for high-precision linear motion applications. This model features a nominal diameter of 40mm and a lead of 20mm, with the direction of the lead being right-handed. Its design includes a flange type C mounting, which is similar to DIN standards, ensuring compatibility with a wide range of installations. The SEM-E-C 40X20RX6-3 is equipped with standard seals and standard axial clearance, offering protection against contaminants while maintaining efficiency in operation. It boasts an adjustable preload mechanism that allows for zero-clearance tuning, enhancing system rigidity and reducing axial play to achieve higher positional accuracy. This capability makes it suitable for applications where precise movement control is critical. With a dynamic load capacity (C) and static load rating (C0), this ball screw nut can handle significant loads while maintaining smooth motion. The product operates effectively within a temperature range of -10°C to +80°C, allowing for continuous use at temperatures up to 80°C and temporary peaks up to 100°C without compromising performance. These temperature thresholds are measured on the outer shell of the nut. The SEM-E-C 40X20RX6-3 conforms to tolerance grade T3 and T5 as per the product overview for screws provided by Bosch Rexroth. Users should note that when operating outside these tolerance grades, adjustment factors must be considered as detailed in the technical notes provided by the manufacturer. This ball screw assembly has a hole pattern BB and belongs to the SEMEC series, offering zero-clearance adjustable single nuts within its category B classification. Weighing approximately . kg, it provides a balance between robustness and weight efficiency for various industrial applications requiring precision linear movement.
