Product description
Parameter details

Through balancing the nut to perform precise adjustment

The torque limiter is equipped with a scale meter, which is convenient for torque adjustment

Re-reset at equal intervals or 360°

No maintenance

Can be equipped with fine-tuning mechanical switch/proximity switch to stop the motor drive, the assembly drive assembly is directly supported by roller bearings

 

on request:

Equipped with a complete set of transmission components assembly (sprockets, pulleys, gears...)

Can be connected through 8 holes, the component can be circulated with other products on the market

Equipped with connecting flange to connect with the most common intermittent drive unit

Mesh can be customized to stage 30 °, 45 °, 60 °, 90 °,..


The Backlash-free torque limiter has high technology and high accuracy. A backlash-free motion transmission is provided through a highly sensitive reaction action, which can be released instantly after reaching the set release torque.


main application

Bottle blowing machines, filling machines

labeling machines and other packaging machinery

CNC tool machinery, indexing table  

Director, powertrain    

Servo motor, guide rail

 

advantages and features

Protect the product in case of overload

Protect the indexing device when the transmission is overloaded

In the event of a collision, protect the mechanical operating unit

In case of collision or limit stop, protect the slide rail or servo motor

Description

▪If the inner hole of the coupling end needs to be enlarged, the standard torque limiter can be equipped with a larger coupling

▪Assembly tolerance: can be processed according to customer requirements

▪The mass is only related to the hole formation, and the inertia only needs to refer to the coupling with the largest opening hole

▪Can be equipped with micro mechanical switch or proximity switch
