Overrunning clutch without bearings (MDEU)

Overrunning Clutches Without Bearing (MDEU): Compact, Maintenance-Free Freewheels in European Design

The MDEU series of overrunning clutches offers a highly compact, maintenance-free and installation-friendly solution for a wide range of industrial applications. As pre-lubricated roller ramp freewheels in European design, these units are ideal wherever no additional bearing support is required. Built for durability and reliable torque control, MDEU freewheels from MOVET combine proven TSUBAKI quality with user-friendly engineering.

Compact Freewheel Without Bearing: Function-Driven Design

The key feature of the MDEU overrunning clutch is its bearingless construction. Thanks to a roller ramp mechanism, the unit operates reliably without the need for integrated or external bearings. This reduces system complexity, conserves space and lowers overall maintenance requirements. For engineers seeking a compact, robust solution for intermittent or unidirectional torque transfer, the MDEU series provides a highly functional and cost-effective answer.

Direct Mounting Without Flange: Fast and Flexible Installation

MDEU freewheels are designed for direct mounting of the drive element to the outer ring. No special flange is required. This simplifies installation and accelerates assembly processes. With standardized dimensions and a compact footprint, the MDEU clutch can be easily integrated into new or existing machinery – a significant advantage for OEMs and designers seeking modular, adaptable drive components. Even in tight mounting spaces, MOVET MDEU freewheels perform reliably and efficiently.

Pre-Lubricated for Immediate Operation

Every MDEU clutch is factory-filled with long-lasting grease, making it ready for immediate use. No additional lubrication is required before or during commissioning. This feature ensures high reliability even under dynamic operating conditions, such as frequent start-stop cycles or changing rotational directions. The selected lubricant is optimized for durability and thermal stability, supporting long service life in industrial applications.

Typical Applications in Machinery and Equipment

MOVET’s MDEU overrunning clutches are used in a wide variety of mechanical systems, including:

• Conveyor drives requiring backstop functionality

• Labeling and packaging machines with reversing motion

• Auxiliary or emergency drives in gearboxes

• Safety disconnects for idle shafts

• Drive trains with rotating mass overruns

In all use cases, the MDEU ensures safe and precise torque disengagement, protecting the drive components and downstream machinery from damage due to reverse torque or overspeed.
