DAF3K-STL
The DAF3K-STL is a spring-applied brake with a flange mount, designed for engagement and disengagement using spring and air mechanisms. It features a low coefficient facing type and offers a dynamic torque of 5,850 pound-inches. The brake requires a minimum disengagement pressure of 62 PSI and can operate at a maximum pressure of 80 PSI. It supports a maximum RPM of 1,300 and accommodates a bore range with a standard keyway from 1.625 to 2.750 inches (41 to 72 mm). The air volume is 2.13 cubic inches when new and 3.80 cubic inches when worn. The brake is constructed with an aluminum finish and has an open construction design. It mounts on a bolt circle of 13.750 inches and has a shipping weight of 139 pounds.
New clutch or brake torque is approximately 40% less than the rated design torque until the friction and drive discs are worn in (lapped, burnished). The wear-in period varies by application. It is advised to use a service factor of 1.5 to 2 when calculating required torque and to avoid selecting a product for continuous duty at its maximum rated torque.
Torque capacity is only one factor in product selection. It is recommended to contact the engineering department for application review and selection assistance to ensure the right product is chosen for the job.
A repair kit containing common wear items is available, and users are encouraged to stock these kits to minimize downtime, especially if the machinery is critical. For pricing and lead time, contact customer service.

The length of time for wear-in to occur varies by application. When calculating required torque always use a service factor of 1.5 to 2. It is not recommended to select a product for use at its maximum rated torque for continuous duty. PRODUCT SELECTION Torque capacity is only one factor to consider when making a product selection.
