Overload Safety Couplings Torq-Tender® & H-TLC

Torq-Tender® Overload Safety Couplings Torq-Tenders are Overload Safety Devices which provide reliable overload protection. When a jam-up or excessive loading occurs the Torq-Tender will reliably and quickly release to prevent system damage. • Standard Torq-Tenders are bidirectional. The torque value is the same regardless of rotation. If specified, the Torq-Tender can be configured at the factory to release at different torque ratings for different rotational directions. • Torq-Tenders are tamper-proof. Once installed, the torque value cannot be changed. This is an important feature that...

Mounting Options Shaft-To-Shaft Mount – Type C The shaft to shaft mount option allows the Torq-Tender to function as a shaft coupling and a torque limiter. Either shaft can be used to drive the load unless an actuating pin model is used where the housing (F Bore) end must be the driver for proper pin operation (see instructions). Through Shaft Mount – Type B The Through Shaft Mount is intended to have a shaft pass though the full length of the Torq-Tender. A component such as a sprocket or sheave is mounted externally on the Torq-Tender. Either the shaft or the mounted component can be used...

Torque Chart For example, if your application speed is 100 RPM and the HP rating is 1.5, then: T (in. lbs.) = 63,025 x 1.5 100 Your calculated torque requirement= 945 in-lbs. Torque is a twisting force that causes rotation and can be theoretically determined with the use of this simple formula: Torque (in. lbs.) = 63,025 x HP RPM It is important to note that there are many factors involved in the selection of the torque value. The calculation above represents a theoretical way to determine a torque value. Consideration should also be given to potentially high start up torques in the drive...

Torq-Tender® H-TLC Torque Limiters The Intelligent Alternative to Friction-Type Torque Limiters. The unique features in the Zero-Max H-TLC give the designer wider parameters in solving overload problems. H-TLC Is Durable. The H-TLC torque limiter is designed for hostile environments. In many applications, a torque limiter may wait for months or years before it is required to disengage. During this time, the torque limiter may be subjected to moisture, corrosion, acids, salts or any number of other contaminants which inhibit the proper operation of the torque limiter and prevent...
