Misumi USA, Inc: Belt drive actuators

The pulleys used in MSA Series Actuators feature precision-machined one-piece steel construction, nickel plated for durability and corrosion protection, and an integral shaft for superior strength.  The timing belts are made of specialty steel cords molded into highly-flexible polyurethane material to protect against damage and deformation.  All MSA Series Actuator models have been extensively tested over tens of millions of cycles with no failures and all have a repeatability of +/-25 µm or better, according to the company.
