Miki Pulley is introducing their unique PBZ Variable Torque Brakes for direct sale to OEM’s in North America. Ideal for variable torque tensioning control in automated packaging systems and similar applications, these brakes provide adjustable and precise torque control.
Unlike conventional mechanical brakes, PBZ Variable Torque Brakes are magnetic particle brakes. They utilize self-contained magnetic particles that slows, stops, holds and restarts a system with repeatable accuracy. The torque is independent of slip speed and is variable from 0 to the rated torque.
The PBZ’s precise fast engagement ensures accurate positioning without jolts or jerking motion. This feature enables repeatable positioning of plastic film including labels, bar codes and other packaging elements with accuracy. Similarly, accurate positioning of wire in electronics and fiber thread in garment fabrication is ensured using Miki Pulley Variable Torque Brakes. A gradual or fast, engagement setting is adjustable for different application requirements. The adjustment range is variable up to the brake’s control circuit capacity.
Another significant feature of the Miki Pulley PBZ Variable Torque Brakes are no wearing components unlike mechanical and similar brakes with calipers and friction surfaces that wear out. PBZ brakes are unaffected by atmospheric conditions so they are well suited for temperature extremes in a wide range of operating environments.
Available in three 24/80V models with rated torque of 3, 6 and 12 Nm, all three sizes have a 400 r/min allowable rotation.
