The ongoing trend towards electrification is driving demand for mechanical screw drives and electromechanical cylinders in virtually all industries. To meet this increased demand, Bosch Rexroth is expanding its range of PLSA planetary screw assemblies with the new intermediate size 48×20. Compared to the next smaller size, high-power applications achieve up to twice the travel speed, performance and productivity at the same rotary speed and with less heat generation.
The new intermediate size complements the already large PLSA portfolio and offers users even more options for a wide range of applications. Presses and dispensing units for example benefit from the increase in performance and productivity. Owing to the higher lead, the same speed level can be achieved at lower rotary speeds. Less heat is generated as a result, which in turn increases accuracy and process stability. Because the load capacities increase with the size, users also benefit from a longer service life compared to smaller lead sizes.
Wider range of applications for PLSA
The durable PLSA planetary screw assemblies are designed for high loads and speeds of up to 50 m/min and allow significantly higher forces compared to ball screw assemblies. Thanks to an innovative system of preloaded individual nuts, cylindrical and flanged, Rexroth planetary screw assemblies achieve dynamic load capacities of up to 544 kN.
Digital engineering and availability
Bosch Rexroth keeps a stock of both the PLSA threaded screws and the nuts so that the customer-specific machined and pre-assembled screws are available with short delivery times.
The simple design of the screw drives with the help of online configurators which guide users intuitively and visually through all the options saves time in engineering. The modules can then be transferred at the click of a mouse to the Bosch Rexroth e-shop, where the prices and delivery times are displayed straight away.
