Tolomatic low-cost belt-drive actuator designed for harsh environments, loads up to 520 lbs

New trapezoidal solid-bearing actuator design optimizes performance in moderate-loading applications requiring high duty cycle and high speed over long strokes Tolomatic’s family of MXB electric belt-drive actuators includes a new solid bearing load-carrying design ideal for harsh environments. The trapezoidal solid bearing provides a rigid, long-lasting bearing system capable of operating in environments that roller bearings would not be able to withstand. With loads up to 520 lbs. (235 kg), speeds up to 100 in/sec (2.54 m/sec) and strokes up to 230 in (5.8 m), the MXB-S belt-drive actuators an economical solution for light- to moderate-loading applications requiring high duty cycle and high speeds over long strokes. The MXB-S actuator can withstand light washdown. “The trapezoidal solid bearing slides along the extrusion, acting as a wiper against contaminants that would clog up a roller bearing belt drive actuator,” said Nick Holmgard, product marketing engineer. The MXB-S is available in six body sizes with in-line motor mounts as well as reverse parallel mounts with 3:1 timing belt reductions. When paired with the ACS servo or stepper EtherNet/IP™-enabled drive and motor package, or with third-party motor and drive utilizing the Your Motor Here® program, the MXB-S actuator is easy to set up and integrate into many applications. In addition to the MXB-S, Tolomatic’s MXB family of high-speed linear belt actuators, offering long strokes with optimal performance, include the MXB-U unguided belt-drive actuator for applications where loads are externally guided and supported, and the MXB-P heavy duty linear actuator with profiled rail bearing and belt-drive drive to achieve heavy loads and high speeds.
