Torque Limiter Sprockets Offer Maximum Protection from Torque Overload

Torque Limiter Sprockets parts

When your equipment and machinery approach torque overload, you’ll be thankful you have a Torque Limiter to protect critical drive components.
Torque Limiters are often used in conjunction with sprockets, which guide the rotational movement of equipment and machinery, and serve as an automatic safeguard against torque overload. They are usually sold separately, but U.S. Tsubaki now offers user-friendly, cost-effective Torque Limiter Sprockets, which come pre-assembled and can be made in various sizes and tooth counts for any application.

How does the Torque Limiter Sprocket work?

The Torque Limiter Sprocket works by transmitting torque via two composite friction disks, which are compressed by disk springs against the ground face of the hardened tooth sprocket. The end-user sets the torque limit by tightening the adjusting nut on the device.

During normal operation, when no torque overload is occurring, the Torque Limiter will transmit torque from the driven shaft to the sprocket via the friction disks. As the drive shaft runs, the spring will compress the friction disks against the sprocket. This creates a frictional force that transmits the power from the drive shaft to the sprocket.
When a torque overload occurs, such as during a mechanical jam, the transmitted power will exceed the set torque point, causing slipping between the friction disks and sprocket. If slipping occurs, the frictional force will no longer be strong enough to transmit the torque from the drive shaft to the sprocket. The drive shaft will continue to run, but no torque will be applied to the sprocket. Once the torque overload is removed, the Torque Limiter will automatically reset and resume transmitting torque.

Applications and Uses for Torque Limiter Sprockets

Torque Limiter Sprockets can be used for a variety of applications where continual movement of the machine is important, including conveyors, gearboxes and motors. The slipping of the friction disks allows the machine to power through temporary jams and load increases without incurring damage. Without a torque limiting device, critical drive components are at risk of failure or breakage from torque overload.

By combining the Torque Limiter and sprocket into one product, customers now have access to a complete torque limiting solution that can be customized for specific applications and machinery.

U.S. Tsubaki offers a wide selection of mechanical protection devices and Torque Limiters for any application. To learn more about Torque Limiter Sprockets and select the right configurations for your facility, contact us today.

Protect Your Cables from Dirt, Grime and Particulates

When selecting the proper cable carrier for your application, consider the environment in your plant.  Are your dynamic cables coming into contact with foreign bodies, such as hot chips, chemicals, or other contaminants that might cause damage to the cables? If so, they might need extra protection.  For example, a machine tool that cuts material such as metal or glass will create shavings, chips, and other particulates that can fall on the cable track. Once inside the cable carrier, these particles will cause wear and tear on the cables and hoses as they move. This could lead to severe cutting and damaging of the cables over time, which may result in cable failure, contribute to downtime, and ultimately, lost revenue.

Selecting the right enclosed cable carrier


Enclosed plastic and hybrid cable carriers offer an additional layer of protection, ensuring that debris cannot enter the carrier. These are ideal for applications where coarse contamination, such as chips, metal parts, glass splinters or hot metal spatter, is likely. In many cases, enclosed cable carriers are also used to hide the cables for aesthetic reasons.

The IP Enclosure Rating indicates the level of protection a cable carrier provides against outside contaminants and can help you select the right cable carrier solution for your needs.


Ensuring maximum protection with the KabelSchlepp® TKA Series

The industry’s highest-rated enclosed cable track is the KabelSchlepp TKA series, which is ideal for environments where machine cutting equipment is manufactured or used. It has an IP54 rating, which means the enclosed cable track will not allow anything down to a dust particle or liquid splash to enter the carrier. This level of protection will help ensure maximum life for your cables and hoses.

The TKA enclosed cable track can be made with a variety of material types for custom applications, including custom molded materials to protect against hot chips up to 850 °C. In addition to the high level of protection it offers, the TKA series cable track uses easy-open lids for installation and inspection – offering access to the cables at any link of the cable track – and operates quietly.
