Esco Transmissions SYNCHRON 35FM AS-250 Torque Limiter

Description

The SYNCHRON 35FM AS-250 from Esco Transmissions is a mechanical torque limiter, also known as an overload clutch. It is designed to provide reliable protection for drive trains by immediately disengaging when a preset torque is exceeded. This unit features automatic re-engagement, which resets the clutch once the overload has passed, minimizing downtime. This specific model includes a 30mm bore with a keyway and comes with a sprocket pre-installed.

FAQ

The SYNCHRON size 35 series typically has an adjustable torque range from 5 to 40 Newton-meters. The exact setting should be calibrated on the device itself according to your application's requirements.

This is a ball-detent type clutch. Upon overload, spring-loaded balls are forced out of their detents, disengaging the drive. Once the overload is cleared and the rotational speed is reduced, the springs automatically push the balls back into their detents, re-engaging the drive at the same angular position.

The sprocket is bolted to the torque limiter flange, as seen by the six hex bolts on the face. This modular design allows the sprocket to be replaced if it wears out, without needing to replace the entire torque limiter unit. You would need to ensure the replacement sprocket has the same bolt pattern and dimensions.
