Mach III Air Engaged-Spring Released Brakes

Mach III air engaged brakes are applied with compressed air and release in the absence of air pressure. They are often referred to as power-on brakes. These brakes are best suited for bringing a load to a stop and preventing rotary motion of a load. The braking torque is linearly proportional to the air pressure applied.   Torque range: 100 to 6,449 lb-in (11 to 728 Nm) Typical applications: Stopping, holding, and cycling

Mach III Air Engaged-Spring Released Clutches

For Mach III air engaged, spring released clutches, the torque transmitted is linearly proportional to the air pressure applied. When air pressure is absent, release springs ensure full separation of clutch discs. As with all Mach III products, a wide variety of configurations are available. Mounting options include NEMA C-face, through-shaft, end-of-shaft, and clutch-couplings.   Torque range: 190 to 41,008 lb-in (21 to 4,633 Nm) Typical applications: Conveyors, belt-driven equipment

Mach III Spring Engaged Air Released Brakes

Mach III Spring Engaged Air Released Brakes   Mach III spring engaged brakes remain engaged in the absence of air pressure. They are often referred to as power-off brakes, fail-safe brakes or holding brakes. These brakes are best suited for applications where they are used to prevent rotary motion of a load and are not suitable for dynamic stopping. These brakes are also available in configurations that mount directly to standard NEMA C-face frames.   Torque range: 59 to 8,775 lb-in (6 to 991 Nm) Typical applications: Food processing, packaging equipment, thermoforming machinery, hoists

Mach III Spring Engaged Air Released Clutches

Mach III Spring Engaged Air Released Clutches Mach III spring applied clutches transmit a fixed amount of torque determined by the spring pressure. When air is applied, it overcomes the spring pressure and disengages the clutch. These clutches feature a machined pilot for easy mounting of a sprocket or sheave. As with all Mach III products, a number of mounting arrangements and options are available to best suit your application.   Torque range: 506 to 24,375 lb-in (57 to 2,754 Nm) Typical applications: Chain and belt driven equipment

XTB Tension Control Brakes

Unlike other brake designs that can direct heat back into the brake, shaft and bearings, the XTB maximizes heat dissipation by deflecting it away from the brake components. This unique airflow design uses fins on the rotor, hub back and calipers to throw dissipated heat into space, not into the brake or shaft. The design also helps draw cooler air around and over the brake. The new, one-piece lightweight rotor pulls cool air into the brake and draws it over the air hoses so they don’t overheat and crack. Torque rating: 2290 lb-in  - 35,280 lb-in (0.2587 kN-m – 3.986 kN-m)
