Q: Do the Torq/Gards and Torq/Gard Couplings, conform to RoHS standards?
A: We are just starting to receive compliant units so if you require RoHS compliant products, please indicate this when ordering.
Q: What is the allowable temperature range?
A: –10°C to 100°C. If the temperature is outside this range, please consult with R.M. Hoffman Company.
Q: What is the life span of the Torq/Gards and Torq/Gard Couplings?
A: The Torq/Gard is rated at one hundred thousand trips; however, if the machine does not stop tripping then the rating is meaningless. If it trips frequently, the trip torque will gradually decrease, so tighten the adjusting nut (bolts) and set screws as necessary.
Q: Can I use the products in an environment where they may be splashed with oil and/or water?
A: The Torq/Gard is sealed so it excels in environments that are wet, oily or dusty. For other series, it is sometimes possible to upgrade them with these specifications. Please contact R.M. Hoffman Company for more information.
Q: I purchased the TG-400 and when I went to verify its torque with our machine, the amount of torque was found to be insufficient. I would like to switch to the TG-800 What do you recommend I do?
A: The only difference between TG-400 and TG-800 are the springs used. If the spring is changed, the TG-400 will become the TG-800. You will need to re-label and adjust the unit. Call us to purchase new springs.
Q: I am currently using a Torq/Gard but it won’t trip when the machine overloads. What do you believe is the likely cause?
A: There is a possibility that the adjusting nut (bolts) have been tightened too much. Excessive tightening eliminates the disk's deflection, causing the Torq/Gard to be unable to trip, thus rendering it useless as an overload protection device.
Refer to the Torq/Gard catalog or Torq/Gard manual for nut rotating angles and torque correlation diagrams. Never exceed the allowable torque limit by over-tightening the nut.
Q: I would like to use a Torq Gard Coupling for my machine. Does it matter which direction the Torq Gard Coupling is installed on the driven or drive sides?
A: It is possible to install a Torq/Gard Coupling in either direction. But be aware that the maximum installable shaft diameter is different on the Torq/Gard side and coupling side.
