JAB Torque Limiters
The Brunel JAB torque limiter can be easily adjusted to your torque setting and is manually reset upon disengagement. During normal operation, there’s no slip, and the torque setting is maintained indefinitely. Special seals are available for dusty operating conditions.
Release torque range: 10 to 4,000 lb-ft (14 to 5,500 Nm)
Typical applications: Conveyors, paper machinery, packaging equipment, machine tools
JB Torque Limiters
Brunel Corporation’s Type JB torque limiters provide instant release at the preset torque. Once the overload releases the clutch, the hub travels one revolution before the clutch automatically re-engages. This makes JB torque limiters perfect for applications where restart must occur in the correct position and where manual resetting is not possible.
Release torque range: 50 to 1,000 lb-ft (68 to 1,356 Nm)
Typical applications: Conveyors, packaging, bottling machines, printing presses, indexing drives
Safeset Coupling
Voith Turbo SafeSet torque limiting couplings protect your equipment from dangerous overloads. In the event of a torque overload, shear tubes break instantly, releasing hydraulic pressure and disconnecting the driveline. Replacing the shear tubes and repressurizing takes only a few minutes.
Torque range: 737 to 14,751,242 lb-ft (1 to 20,000 kNm)
Typical applications: Steel mills, crushers, grinders, conveyors, excavators, gas turbines, trains
SE Torque Limiters
Brunel Safety Element (SE) torque limiters are specifically designed to protect very high torque applications from overload. This modular system allows for a virtually unlimited torque capacity. SE clutches operate with no slip and completely disengage when a torque overload occurs. Special units for waste water and other outdoor, corrosive environments are available.
Tangential force range: 2,250 to 38,000 lb (10,000 to 169,000 N)
Typical applications: Waste water treatment, mining, extruders
SL Torque Limiter
PT Tech’s SL series torque limiter is designed specifically to protect mining applications. Since this is a friction-type torque limiter, no reset is required after a slip occurs. While slipping, the torque limiter will continue to transmit torque equal to the unit’s torque setting.
Torque range: 3,312 to 4,584 lb-ft (4,490 to 6,215 Nm)
Typical applications: Mining equipment
SLQ Torque Limiter
PT Tech’s SLQ series torque limiter requires no adjustment or lubrication. Since this is a friction-type torque limiter, no reset is required after a slip occurs. While slipping, the torque limiter will continue to transmit torque equal to the unit’s torque setting.
Torque range: 438 to 3,828 lb-ft (594 to 5,190 Nm)
Typical applications: Mining, steel, material handling
Smartset Coupling
The Voith SmartSet torque limiting coupling is able to slip up to 120° without releasing during short duration torque spikes. If the overload lasts longer, the coupling will fully release in order to protect the driveline.
Torque range: 737 to 14,751,242 lb-ft (1 to 20,000 kNm)
Typical applications: Steel mills, crushers, grinders, conveyors, excavators, gas turbines, trains
