Signature Series Overview

Simple.

Setup with ease-of-use in mind, the Signature Series has eight product lines based on industry-demanded standard features, all at no extra cost or lead time. The brake selection process can be difficult, especially if there are late-stage project changes. The simplified portfolio will decrease the duration of your selection process.

The Signature Series increases clarity and reduces complexity by offering an easy-to-select product line with standard options configurable to your order.

Local.

Being Local does not mean holding a product in a warehouse from overseas and drop shipping it to a customer. It means it’s manufactured in the USA. It means the technical support is in your time zone, speaking your language.

The Signature Series increases operational flexibility while reducing risk by providing locally manufactured and supported product lines.

Stocked.

The number one request from strategic purchasing departments is product availability. Combined with complicated ordering requirements and long lead times from overseas, safety brake availability has become a complex equation. Availability should be quick and easy – available in as little as five days.

The Signature Series removes the need for stocking programs & extended forecasting while adding confidence to your end customer by stocking configurable product with short lead times and flexible options.

The simplest way to receive Stearns products, manufactured & supported in the USA - in as little as 5 days!

Solenoid Actuated Brakes (SAB)

SAB | NEMA C-Face Motor Frame Brakes

NEMA C-Face Motor BrakesSolenoid Actuated Brakes (SABs) can be mounted directly to an electric motor or foot mounted. The compact design delivers high torque 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 and ensure automatic stopping and holding any time power to the brake is interrupted.

AAB | Metric Motor Frame Brakes

Metric Frame BrakesThe Armature Actuated Brakes (AABs) are spring-set, electrically released, friction devices, which develop holding and braking torque in the absence of electrical power. This type of 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.
