LINEAR MOTION CONTROL Technical Data Sheet Nexen’s I300 brake is designed for zero backlash holding and emergency stopping making it ideal for indexers and positioning systems. The spring engaged, air released, patented braking element locks and holds the shaft in position without any displacement or reversing of the load. It is flange or shaft mounted and has a keyless compression bushing shaft connection for easy installation and IP67 rated when flange mounted. High torque and short response time ensure the shortest possible stopping distance and precise holding. Brakes can be stacked for additional holding power or redundant braking. Features • Zero backlash • Torque up to 600 Nm [5311 in-lbs] • No shaft rotation due to brake actuation • Shaft end or through shaft mounting • Capable of 2000 RPM • Spring engaged, air released • Releases at 4.1 Bar [60 psi] • Stackable for higher holding power or redundancy
