MIKI PULLEY STARFLEX MIKI PULLEY STARFLEX Applications Drive High damping High flexibility High torque Easy to mount and remove Machine tools, hydraulic equipment, pumps, fans, conveyors, textile machinery Servo motor, stepper motor, induction motor Wide range of variations General-purpose Coupling of Simple Construction Motive power is transmitted by a polyurethane elastomer that has the elasticity of rubber. As well as providing excellent absorption of vibrations and shock, these couplings transmit more than double the torque of older jaw couplings. The product range includes three types of hubs, two element hardnesses and two types of fit. This ensures the optimum combination for your transmission torque, response and misalignment. And the ability to combine different hubs means they can be used in a wide range of applications. ■ Various Types of Combinations The line-up includes three types of hubs: pilotbore products that allow free bore drilling, key/ set screw types that enable high transmission torque, and clamp types that are easy to mount and remove. Optimal design of the element shape reduces mounting error counterforfce to not damage the shaft. ■ Shaped like older models Torque transmission surface has linear shape Torque transmission surface has arched shape ■ ALS(B) types Convex shape (crowning) The R and Y types have no backlash and yet can absorb shock and vibration. The shape of the torque transmission surface is linear. The shape of the torque transmission surface is arced. Combined with an undercut to reduce mounting error reaction force. It is also made more flexible by its crowning shape and by removing material from the inner

There are three MIKI PULLEY STARFLEX models. Each has a different type of element. ELECTROMAGNETIC CLUTCHES & BRAKES These are JIS A tight-fit, high-torque, highresponse models that have a shore hardness of 97. These are JIS A tight-fit models that have a shore hardness of 90 and are equipped with a good balance of torque transmission performance, flexibility, and responsiveness. These are JIS A loose-fit, high-torque, flexible models that have a shore hardness of 97.

MIKI PULLEY STARFLEX Customization Examples ■ Intermediary Shaft Types Standard These are long types combining two couplings and a shaft, These are short types with an additionally processed hub, and can be used when distance between shafts is long. and can be used when wanting to shorten the entire length. ■ All-Processed Clamp Types High-precision-processed hubs ensure a high degree of concentricity, to lower unbalance. These are easy-to-handle clamp types. For details, please visit our website. 132 For inquiries on customization

How long is the MIKI PULLEY STARFLEX service life? If power transmission is your primary goal, select an appropriate coupling using the selection procedures of the catalog, then you can expect long-term use. Service life will vary with usage environment and conditions and is heavily affected by usage temperature and mounting misalignment. Contact Miki Pulley for details.
