Words
Q1 | What is the compliance with the RoHS directive? |
---|---|
A1 |
The TGB and TGX series are already compliant. For the TGM series, the changeover is being made progressively. If you need RoHS-compliant products from the TGM series, specify "RoHS-compliant" in your order. Back to questions |
Q2 | What is the allowable temperature range? |
A2 |
The body temperature should be between -10℃ and +100℃. Some coupling series have an upper limit of 80℃. Contact us for use outside this temperature range. Back to questions |
Q3 | Tell me about the life span of the products. |
A3 |
It depends on the conditions of use and cannot be answered definitively. Back to questions |
Q4 | Are there any precautions to be taken when using the TGM series in an environment where water/oil splashes on it? |
A4 |
The TGM series has seals and gaskets to prevent dust, oil and water from entering the parts inside the case, but noted that camshafts and adjusting screws exposed from the case will be subject to corrosion rust caused by water and steam. Back to questions |
Q5 | We purchased the TGB30-L but the torque was insufficient when we checked it with the actual equipment. We want to change to the TGB30-H. What can we do? |
A5 |
The only difference between the TGB30-L and TGB30-H is the spring. If the spring is changed, the TGB30-L will become the TGB30-H, but the torque indicator labeled on the product can no longer be used for set torque adjustment. Although you can use the product with no problem, if you need a torque indicator, you can return to us. We will change the disk spring, set the torque to the minimum point, label the correct torque indicator, and deliver the product to you. Contact your local dealer for more information.

Q6 | We used the Shock Guard but it did not trip when the equipment overloaded. What is the probable cause? |
A6 |
There is a possibility that the adjusting nut (bolt) has been tightened excessively. Excessive tightening eliminates the disk's deflection, preventing the Shock Guard from tripping for overload protection. Refer to the "Tightening Amount - Torque Correlation Chart" in the catalog or instruction manual to confirm the angle of the adjusting nut rotation. Be sure not to exceed the upper limit of the set torque range. Back to questions |
Q7 | We want to use a Shock Guard Coupling. Are there any specific directions for installing it, on the driven side or drive side? |
A7 |
There is no specific direction. You can install the Shock Guard Coupling on either side. Note that the maximum shaft bore diameter is different between the Shock Guard side and coupling side. Back to questions |
Q8 | We want to use a high precision TGX for a high speed shaft, but it cannot stop instantaneously after a trip. Is there something you can recommend? |
A8 |
Special series allows complete release without backlash. Contact us for more information. Back to questions |
Q9 | We want to install a sprocket on the TGB series. What are the recommended sprocket machining dimensions? |
