New High-Torque Brake from Rexnord/Stearns


The Stearns® Division of Rexnord Industries, LLC, has launched a new high torque brake designed to easily fit into the drive system of any type of heavy industry equipment. The Series 7EC Electric Caliper brake is spring-set/electrically-released and is used for dynamic stopping, E-stop, and/or holding-only applications. The floating caliper design compliments a variety of tough industry equipment including material handling systems, commercial elevators, industrial lifts, wind turbines, hillside trams, and lock-gate hoists for hydro-electric dams.

“Stearns is the number one supplier of spring-set electrically-released motor brakes in North America,” says Gary Zwick, Stearns product manager. “The new electric caliper brake will continue to bring our customers a top of the line product with efficient technology that outlasts the competition, meaning lower maintenance costs and increased productivity.”

Part of that efficiency is the brake’s ability to easily adapt to drive systems. The disc can be mounted in several locations including directly to a drive shaft (i.e. the disc can incorporate a hub with a QD bushing), bolted to a coupling hub, or directly to large motors since manufacturers can fit the disc to an extended shaft on accessory end of motor. High capacities in torque (500-5,000 lb.-ft.) and speed (up to 10,000 surface feet per minute) are also part of the product’s easy to use design. A high thermal capacity provides additional user versatility through the ability to incorporate gradual stops for high inertia loads.

The brake’s electrical operation eliminates the need for hydraulic or pneumatic components or systems, bringing users a simple, clean and low-maintenance installation. An optional environmental/corrosion protection package that meets IEEE 45 requirements for marine/maritime applications is also available. For more information go online to
