SafeSet offers outstanding precision and reliability by protecting all components in the driveline
Rotating equipment drivelines are long-term investments worth protecting. Every minute of unplanned downtime caused by overload is a loss in production. With outstanding safety and reliability, Voith’s torque limiting couplings protect all components in the driveline, resulting in smooth operation, less wear and tear, and maximum performance of your equipment.
Benefits at a glance
Offering you outstanding precision and reliability through
Accurate release torque: Increases productivity
Compact and customized design: Easy driveline integration
Set torque that remains constant over time: No unwanted releases, which reduces repair time
Instant torque limitation in an overload situation: Protects the driveline and avoids expensive standstill costs
Product details
Voith's comprehensive product portfolio covers a range of torque limiting couplings with capacities from 1 to 20,000 kNm.
Tailor-made designs provide additional advantages to the production process. SafeSet, SlipSet, SmartSet, and AutoSet ensure the safe operation of the driveline by releasing or slipping at an exact torque level. In the event of a catastrophic, high-torque occurrence, the torque limiting couplings interrupt the power flow in the driveline, which minimizes damage and production downtime. The Voith Dtect System alerts you in real-time about torque overload situations, helping further protect your investment.
SafeSet – coupling with instant release
SafeSet protects your driveline and maximizes production.
Protect your driveline and maximize production with a SafeSet. The principle is simple and based on friction and adaptability principles. No material fatigue or wear ensures constant torque protection during operation. The torque limiting coupling includes a twin-walled hollow sleeve. Friction is generated upon expansion by pressurized hydraulic oil. The integrated shear tube holds this pressure to ensure a constant but easy adaptable torque transmission. In an overload situation, the SafeSet slips, and the shear tube shears off. Oil pressure drops, and the frictional surfaces separate. Consequently, the SafeSet rotates on the bearings without transmitting any torque.

SlipSet – coupling with peak shaving
SlipSet is designed with the ability to slip instantly instead of releasing in the event of a torque overload.
Ensuring continuous production, the SlipSet is designed to slip in the event of an overload situation. Acting as a shock absorber in drivelines with frequent torque peaks, this torque limiting coupling safely prevents time-consuming repair work and shutdowns. This coupling is compact in design and can be installed in areas with limited space; this ensures optimal positioning in the driveline. The SlipSet torque limiting coupling is ideally suited for applications requiring short peak loads (smaller than slip angle 120°).
In a temporary torque overload, the coupling slips to limit the torque peaks and enables continuous production. If the blockage persists, the SlipSet coupling slips until the drive can be stopped for the obstruction to be cleared. To monitor the maximum slip angle possible, we recommend using the Dtect torque system.m.
Features and benefits
Design features
- Ideally suited for applications requiring short peak loads
- Adjustable torque settings from 50 to 100% of maximum torque setting
- Slip at a pre-set torque
- Immediate slip in the event of a torque overload
Benefits
- Ensures continuous production due to torque limitation without disengagement
- Minimized installation cost thanks to a compact design
- Less maintenance cost due to instant overload protection that protects your driveline from premature wear
SmartSet – coupling with peak ride through and controlled release
Torque limiting couplings from Voith prevent machine damage in high-value rotating equipment. They work like a mechanical fuse in the driveline by protecting the system from costly breakdowns.
SmartSet is a torque limiting coupling with controlled slip based on the same technology as SafeSet, with the additional ability to also slip without releasing, to reduce the short duration and dynamic torque peaks without interrupting production. The SmartSet principle is simple: controlled slip torque for process improvement. The SmartSet coupling can safely slip up to 120° without releasing to limit short peaks. If the torque peak is of long duration in an overload situation, the SmartSet coupling will fully release and save the driveline from severe damage.
Features and benefits
Design features
- Ability to slip up to 120° during a torque peak
- Adjustable torque settings from 50 to 100% of maximum torque setting
- Mechanical slip and release mechanism
Benefits
- Ability to slip without release to reduce the short duration and dynamic peak torques
- Precisely adjustable slip and release torque
- Maximum driveline protection
- Full release during blockage
AutoSet – coupling with peak ride through and automated reset
AutoSet automatically resets the pre-set torque limit after a longer overload/complete blockage.
Controlling the slip and automatically resetting to improve performance and minimize production stoppages, this process-improving torque limiting coupling handles dynamic torque peaks of short duration safely and without releasing. The AutoSet reduces high torque peaks by slipping up to 180°. If the torque peak lasts long, the coupling will release entirely, limiting the torque.
Features and benefits
Design features
- Ensures continuous production due to torque limitation without disengagement
- Complete disengagement during a long peak event
- Automatically resets itself to the pre-set torque limit after a longer overload/complete blockage
Benefits
- Improves production, as no resetting is needed for short peaks
- Lower maintenance cost with no manual resetting needed
- Less investment cost, as no additional equipment is needed
- Continuous operation, even during an overload, improves production uptime
