The RSA-HT high-force rod-style actuator from Tolomatic (Hamel, MN) can also be considered as a replacement for hydraulic applications and offers maximum force capabilities of 12,900 lbf (57.38kN). Features include an IP67 option, standard purge/breather port, and a lubrication system. The actuator includes a grease zerk for lubrication without disassembly. The purge/breather port allows positive pressure to be applied to the actuator to help keep contaminants out, and functions as a breather port in high-speed applications where internal pressures may exert additional forces on the actuator if sealed.
The actuator with reverse-parallel configuration has a high-torque belt design for driving maximum force output. A polyurethane timing belt with carbon tinsel cords is available in 1:1 or 2:1 reduction configurations. The 1:1 configuration allows for reduction gearbox mounting, reducing the overall footprint of the actuator. It is available in three sizes (32, 50, and 64) and in strokes up to 60" (1524 mm).
