CHARLOTTE, NC – Bosch Rexroth has extended its line of PSK Precision Modules to include the PSK 40, now the smallest size in its product line. The new size PSK brings high-precision solutions to medical, semiconductor, and small machining applications, where high stiffness and rapid cycle times are required. To speed deliveries, Bosch Rexroth has also localized assembly of the most common PSK models in the U.S., with the most popular, the PSK 60, now available in three days.
The PSK 40 module provides industry-leading speed and length capabilities in this size range. Maximum speed is 375 mm/s, almost twice the speed of competitors’ offerings, allowing faster cycle times and higher throughput. Maximum length for the PSK 40 is 350mm, whereas competing modules are available only up to 200mm. The extended length capability of the PSK 40 reduces the need to use a larger module for longer stroke requirements, saving the user space and cost.
Common to all PSK sizes (40, 50, 60 and 90 mm widths with standard lengths from 100mm to 940mm) is easy installation and alignment, made possible by the machined reference edge on the main PSK body. The single point lubrication system for the ball rail system and the ball screw assembly reduces maintenance costs significantly. The steel base also provides high rigidity, making the PSK well-suited for high-performance, small to medium multi-axis systems.
