Used to stop non-powered/ gravity rollers from spinning. A pneumatically activated steel channel with a high friction top surface presses against the bottom of a series of non-powered conveyor rollers to prevent them from turning. When air pressure (60PSI or more) is sent to the brake, the brake releases from the rollers. Removing that air pressure allows the spring to return the brake channel against the bottom of the rollers. Brake will still stay engaged in the event of air pressure loss. Available in 2’, 3’, & 4’ lengths for 1.9” diameter non-powered roller conveyors.
