Great value for money

Compared to other mechanical clutches in this torque range, the TL500 offers excellent value. The chain-type design seems much more durable than friction disc models we used previously.

Reliable overload protection

Using this in an agricultural irrigation pump setup. It has saved us from several costly repairs due to debris clogging the intake. Highly recommended for heavy-duty applications.

Works as advertised

No complaints about performance. It slips exactly at the set limit. The only minor issue is that it requires a bit of space around the coupling for maintenance access.

Solid build quality

The construction feels very robust. Installation was straightforward with the provided keyway specs. Only giving 4 stars because the instruction manual could be more detailed regarding torque calibration.

Perfect for our conveyor system

We installed the TL500 on our chip conveyor last month. It handled a jam perfectly by slipping immediately, preventing any motor damage. Reset was instant once the blockage was cleared.

Essential safety component

This device gives us peace of mind running our automated systems overnight. If something gets stuck, the limiter protects the drive train without needing an operator to intervene immediately.

5 FAQ

Q: Does this model require manual resetting after a torque slip event?

A: No, the TL500 features an automatic re-engagement mechanism. Once the overload condition is removed and speed synchronizes, it resets itself automatically.

Q: Can this be used in outdoor environments exposed to rain?

A: Yes, the unit is zinc-plated for corrosion resistance and is suitable for outdoor use in standard weather conditions, such as in drip irrigation systems.

Q: Can I adjust the torque slip threshold myself?

A: Yes, the TL500 includes an adjustable spring mechanism that allows you to calibrate the slip torque within a specified range. A torque wrench is recommended for precise setting.

Q: Is lubrication required for the chain mechanism?

A: The unit comes pre-lubricated from the factory. However, for extended life in high-cycle applications, we recommend light lubrication every 6 months.

Q: What is the maximum bore size this coupling can accommodate?

A: The TL500 supports bore diameters ranging from 20mm up to 45mm. Please refer to the technical datasheet for specific keyway dimensions for each size.
