Belt backstop (BSEU)

The BSEU series comprises pre-lubricated sprag type freewheel clutches in European design, which are specially designed for backstops. They have an integrated torque arm on the outer ring and are equipped with high-performance V-ring gaskets. Tsubaki's unique, self-lubricating clamping body/roller mechanism ensures a longer service life. The BSEU-2GD series is additionally equipped with a lip seal and an outer cover to ensure improved protection against dust and splash water.

TSUBAKI Belt Backstops BSEU, compact and reliable anti-reverse protection for conveyor systems

The BSEU series of belt backstops from MOVET provides robust, pre-lubricated sprag clutches designed for effective backstopping in inclined or vertical conveyor applications. With high torque capacity, integrated sealing, and easy installation via an outer torque arm, BSEU backstops deliver durable, low-maintenance performance.

Pre-lubricated sprag clutches for long-term operation

BSEU freewheel clutches feature a self-lubricating clamping body/roller mechanism, eliminating the need for regular relubrication. These components are factory-filled with long-life grease, ensuring smooth and quiet operation even under demanding load cycles. Ideal for hard-to-access installations where uptime is critical.

Integrated torque arm, easy installation and secure engagement

Each BSEU backstop includes a torque arm on the outer ring, simplifying alignment and mechanical fixation. This design ensures direct and secure backstop engagement with minimal space requirements – a key benefit in compact drive arrangements.

Enhanced protection with BSEU-2GD variants

The BSEU-2GD series offers advanced sealing with a lip seal and external protective cover, in addition to the standard V-ring gasket. This ensures reliable protection against dust, dirt, and splash water, making these backstops ideal for use in harsh industrial environments.

Broad torque range from 151 Nm to over 5000 Nm

MOVET offers BSEU belt backstops in multiple sizes to support a wide torque range – from mid-duty models at 151 Nm up to heavy-duty versions exceeding 5000 Nm. These freewheels are engineered for both standard conveyors and high-load vertical transport systems.

Available with or without bearings – adaptable to your system

Depending on installation requirements, BSEU backstops are available with integrated bearings for easy handling and mounting, or without bearings for more compact, system-specific arrangements. Both variants offer excellent reliability and vibration resistance.

Optimized for conveyors, bucket elevators, and gearboxes

MOVET’s BSEU backstops are suitable for use in belt conveyors, inclined lifts, vertical drives, gear reducers, and rotary systems requiring anti-reverse functionality. Their compact design, advanced sealing, and easy installation make them a go-to solution for OEMs and maintenance teams.
