A new RSH electric hygienic rod-style actuator has been released by Tolomatic, delivering clean, continuous control to automation machinery. RSH actuators are designed to help improve repeatability, enhance quality, reduce contamination potential and increase flexibility of hygienic machine designs, particularly for the food, beverage, medical, healthcare and pharmaceutical industries.
“We designed the RSH for ‘mission critical’ hygienic applications,” said Andy Zaske, vice president of sales and marketing for Tolomatic. “For the past 10 years we have been delivering stainless actuators into hygienic applications. The RSH builds off all of that learning and delivers maximum design flexibility, 24/7 reliability for high-duty cycles, exceptionally clean operation and enhanced control to give machine designers better efficiency, quality and yield.”
The RSH is clean-in-place (CIP) compatible, allowing designers to achieve open machine designs, and rated IP69K to withstand high-pressure washdown. The front-face sealing O-ring ensures a hygienic design from head to toe. The polished all-316 stainless-steel, smooth exterior resists corrosion and eliminates the need for protective shielding, which simplifies and lowers the cost of machine design. Design engineers can leverage the Tolomatic Your Motor Here® database to select from a variety of stainless steel motor manufacturers for a complete all stainless hygienic package.
A dual-seal system protects the internals of the actuator, and the new innovative quick-change seal cartridge makes it easy to replace seals out in the field without special tools. This ability to change out the rod seals (a wear item) on the machine provides much easier maintenance, lower costs and helps insure long life for the actuator. Additionally, a hygienic breather/purge port can be used to further help prevent contaminants from entering the actuator.
The RSH is designed for forces up to 7,943 lbf (35kN), speeds up to 20 in/sec (498 mm/sec) and stroke lengths up to 48 in. (1200mm). It is available in both ball screw and roller screw options. While ball screws are an economical option with medium life and force capabilities, roller screws (manufactured by Tolomatic) provide higher force capability, increased life and improved accuracy.
All Tolomatic actuators are designed with Endurance TechnologySM, a Tolomatic design principle that incorporates features designed for maximum durability and extended service life.
