What is a sprag type freewheel?
Sprag type freewheel clutches enable reliable, high-torque transmission in a compact format. They precisely block rotation in one direction while allowing free movement in the other – making them ideal for use in mechanical and plant engineering.
High-Performance Sprag Clutches for Reliable Torque Control in Industrial Drives
Sprag clutches are essential components for precise and reliable torque transmission in mechanical drive systems. They lock rotation in one direction while allowing free rotation in the opposite direction – automatically and without external controls. Thanks to their compact size, high torque capacity, and robust construction, sprag clutches are ideal for applications in mechanical and plant engineering. MOVET offers a wide range of industrial-grade sprag clutches tailored to meet technical requirements in diverse applications, from compact drive units to heavy-duty systems.
Compact Design: High Torque Transmission in Minimal Space
One of the key advantages of sprag clutches is their ability to transmit high torque within a compact design. MOVET offers clutches in various torque ranges to suit different technical needs: 1–150 Nm for precision automation, 151–300 Nm for light conveyors, 301–700 Nm for mid-range processing systems, 701–3000 Nm for robust industrial drives, and 3001–5000 Nm for heavy-duty systems requiring maximum load capacity. This broad selection ensures optimal system integration without oversizing.
Three Proven Types: BB, TFS, and TSS Clutches
To meet specific application needs, MOVET provides three main types of roller ramp clutches: Type BB is the standard solution for general-purpose applications, offering reliable torque locking in a compact and durable format. Type TFS is engineered for high-torque industrial tasks, providing reinforced construction for demanding environments. Type TSS is designed for high-speed systems that require rapid engagement and precision torque control. All types are available with or without integrated bearings, depending on system architecture and space constraints.
Optional Centrifugal Lift-Off: Reduce Wear and Extend Service Life
For systems with regular idle phases or overrunning operation, MOVET offers sprag clutches with optional centrifugal lift-off. This mechanism disengages the clutch at a defined speed, reducing internal friction and wear. Choose lift-off variants for systems that operate with frequent decoupling cycles, or non-lift-off designs for continuous operation. Selecting the right version depends on the motion profile and speed dynamics of your drive application.
With or Without Bearing: Flexible Clutch Integration for All Systems
MOVET sprag clutches are available in both bearing-supported and non-bearing designs. Bearing-supported units simplify alignment and offer added stability, ideal for standalone modules or dynamic shaft loads. Non-bearing versions allow for minimal dimensions and are suitable for use with external bearing arrangements or compact housings. This flexibility allows precise matching of the clutch to the mechanical design.
Typical Applications for Sprag Clutches in Machinery and Automation
MOVET sprag clutches are used in a wide range of industries, including conveyors, packaging machines, gearboxes with backup drives, backstops in transport systems, and tooling machines. Wherever controlled engagement or one-way motion is required, MOVET clutches deliver operational security, system longevity, and mechanical precision.
Advantages of MOVET Sprag Clutches: Compact, Durable, and Low Maintenance
MOVET clutches offer high torque performance in a compact footprint, automatic one-way engagement without control systems, optional centrifugal lift-off for wear reduction, bearing or non-bearing configurations, and three specialized types (BB, TFS, TSS) to meet a wide variety of mechanical demands. They are easy to integrate into existing or new systems and often operate maintenance-free under normal conditions. MOVET stands for industrial-grade quality, technical expertise, and responsive support – whether for prototypes or serial production.
