SOLENOID ACTUATED BRAKES

Stearns offers the most comprehensive line of solenoid actuated brakes (SAB’s) on the market today. We have earned the reputation as the industry’s quality leader by working closely with you,our customers, understanding your needs and developing products with design features to handle your most challenging applications. We have installed millions of Stearns brakes worldwide since 1935. Many brakes operating today are 40 years old or more; evidence of our product quality and reliability. Stearns motor brakes can be mounted directly to an electric motor or foot mounted. The compact design delivers high torque in a small size with fast, positive response and no residual drag when released. Our brakes can be mounted directly onto NEMA C-face motors without special alignment procedures. Many motor manufacturers offer a brake kit which will convert a stock fan-cooled motor into a brakemotor. Stearns Solenoid Actuated Brakes feature unitized construction which makes servicing friction discs easy using only a screwdriver and wrench. The Stearns SAB ensures automatic stopping and holding any time power to the brake is interrupted. And, as with ALL Stearns products, the friction material is nonasbestos. We can produce a brake which meets your specifications, including metric mounting. Chances are, we’ve already manufactured similar requirements from a long list of pre-engineered options.

SELF-ADJUSTING DISC BRAKES

Remote inaccessible locations or high cycling applications require a specially designed, low maintenance brake that will operate at peak efficiency and provide uniform braking for longperiods of time. Stearns exclusive self-adjusting feature helps eliminate the major cause of brake maintenance - friction lining wear. Self-adjusting brakes are also well suited for applications where rapid cycling requires frequent resetting of solenoid air gap. Automatic adjustment also eliminates the errors that can occur with hand adjustment. They can be easily modified to suit your particular application. Depending upon the series you select, these brakescan be direct mounted on motors ranging in size from NEMA 182TC through NEMA 505C.

MANUALLY ADJUSTED DISC BRAKES WITH AUTOMATIC RESET

It’s an unbeatable combination; the features you want most in spring-set disc brakes. Standard features now include: a unique spring design which allows for universal mounting, an air gap adjustment gauge for visual recognition that the brake needs adjustment, a new patented hub design, and genuine Stearns friction discs which are trademarked and patented. The 56 SeriesBrakes come in static torque ratings from 1.5 through 25 lb-ft with NEMA C-face mountings 56C, 143TC, 145TC, 182TFC and 184TFC. Ten different housing, endplate, and release configurations, with a wide variety of preengineered modifications, you can select from 120,000 possible combinations! In addition, for holding applications where friction disc wear is not a factor, Stearns 87,000 Series Brakes are available with an optional manual adjust. The 87,000 Series Brakes are available in static torque ratings from 6 lb-ft through 105 lb-ft, with NEMA C-face moutings, 182TC through 286TC.

BRAKES FOR HAZARDOUS LOCATIONS

Although rugged Stearns Brakes are built to withstand rigorous industrial environments, many applications require additional protection from explosive gases or ignitable dusts.Stearns manufactures a complete line of disc brakes designed from the hazardous locations defined in the National Electric Code (NEC). Each brake is labeled to show the Class, Group, and maximum operating temperature of the brake enclosure. We offer both motor-mounted and footmounted designs, and all Stearns Hazardous Location Brakes are UL Listed and CUL or CSA certified.

DOUBLE C-FACE DISC BRAKE COUPLERS

Stearns Disc Brake Couplers provide maximum versatility, allowing you to add a brake to a C-face motor with a single shaft extension. Using these reliable products, you can couple a C-face motor to a C-face gear reducer.

MARITIME AND NAVAL BRAKES

Are designed for U.S. Navy and Coast Guard military specifications.These units conform to MIL-B-16392C or 46CFR 110.10-1 and IEEE Standard 45. Specialmaterial components help prevent corrosion due to shipboard environments.SAB’s used in marine environments can be custom built to meet the specifications. In addition, all Stearns SAB’s are “Type Approval Certified” by the American Bureau of Shipping. Today, Stearns is focused on being your worldwide, value-added supplier. Our factory-trained field sales force is available to work with you in person to determine your application needs, as well as provide training and support to your engineers andmaintenance staff. Our extensive network of more than 900 distributor branches is your assurance of quality service after the sale. Stearns is a division of Rexnord Industries, LLC, a world leader in power transmission products. We have the resources, experience and dedication to meet your industrial brake, clutch and solid-state electronic centrifugal switch needs.

TRADEMARKED AND PATENTED FRICTION DISCS

Now you can rely on identifying genuine Stearns Friction Discs which assure continuous, reliable performance backed by the Stearns name.A molded ring in the Stearns friction discs makes it easy to visually identify a Stearns disc. The new splined discs are trademarked and patented by Stearns Division, Rexnord Industries, LLC.

Spring-Set (Power-Off) Motor Brakes

Solenoid Actuated Brakes NEMA C-Face Mount

Stearns Solenoid Actuated Brakes (SABs) are spring-set, electrically released, utilizing a solenoid and lever arrangement to release the brake. SABs are available in many configurations including Close Coupled, Double C-face, Division 1 or Division 2 Hazardous location, Foot Mounted, and Navy/Maritime/Marine Duty. SABs mount directly to a NEMA C-face motor.

Armature Actuated Brakes • DC Direct Acting

The Armature Actuated Brakes (AABs) are spring-set, electrically released direct-acting brakes which develop holding and braking torque in the absence of electrical power. Direct acting brakes use a magnet that pulls directly on a plate (armature) to release the brake. This brake can decelerate and hold a rotational load or can be ordered to provide a holding function only, where the motor is used as the dynamic brake.
