***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth SEM-E-C 16X5RX3-4 (R151201055) is a high-precision ball screw assembly designed for linear motion applications requiring exact positioning and repeatability. This adjustable preload single nut SEMEC is engineered with a flange type C mounting, compatible with DIN standards, ensuring easy integration into various machine designs. The ball screw has a nominal diameter of 16 mm and a lead of 5 mm, moving to the right, which indicates the direction of lead. Equipped with standard seals and standard axial clearance, this model maintains its performance by protecting against contaminants while allowing for minor adjustments in preload to reduce axial play for improved rigidity and precision. The SEM-E-C 16X5RX3-4 features a tolerance grade T, which is consistent across sizes as detailed in the product overview for screws. With a dynamic load capacity C and static load rating C0 specified for tolerance grades T3 and T5, users must apply correction factors for other grades as outlined in the technical data notes. This ball screw can operate within a temperature range of -10°C to +100°C continuously, handling temporary peaks up to +120°C measured on the outer shell of the nut. The SEM-E-C 16X5RX3-4 also boasts an impressive maximum permissible linear speed vmax, contributing to its operational efficiency. The product's zero-clearance adjustable single nut design ensures minimal backlash while maintaining high stiffness and load capacity. It comes in size L1 with a weight of approximately 0.45 kg, making it suitable for various industrial applications where weight and space are considerations. Overall, this Bosch Rexroth ball screw assembly represents a reliable component that combines durability with precision engineering to meet demanding linear motion requirements across different applications without sacrificing performance or longevity.
