1.Determine the required slip torque from the loading conditions or from the design strength of the machine. If the loading conditions of the machine are unknown, set the required slip torque of the torque limiter to 1.5 ~ 2 times the torque the motor produces on the shaft where the torque limiter is mounted.
2.Select a torque limiter that has enough torque range and bore range.
3.Determine the proper bushing length from the thickness of the center member to be inserted between the friction facings. Always choose the largest bushing which does not exceed the width of the center member being shown as max.” in the dimension table.
1.The center member should be machined on its rubbing surface to obtain the rated torque and be flat, parallel, square with bore, and free from rust, scale, and oil. Surface finish recommended is Ra 1.6. If the center member is not in accordance with these specifications, the slip torque will be erratic.
2.Bore of the center member to be machined is shown in the table below. Also, min. numbers of sprockets teeth to be used and bushing length to be chosen are listed in this table.

TORQUE SETTING
TORQUE SETTING- Torque setting of the torque limiter is achieved by tightening or loosening the adjustment bolts and/or the adjustment nut. For torque adjustment of TL50 through TL89 , an adjustment nut is provided, and for TL127 through TL178 , adjustment bolts are provided.
- The torque setting can be made after mounting the torque limiter on the shaft. The process is:
- For TL50 through TL89,
First, rotate the adjustment nut tightly by hand so that the disk spring can fit the plate. Then tentatively tighten the nut by about 60 degrees with a wrench.
Rotated Angle and Setting Torque
Rotated Angle (degree)
- For TL127 through TL178,
First, rotate the nut for fixing the disk spring to the plate, and then tighten each adjustment bolt by about 60 degrees. Then, if the torque limiter slips under normal loading conditions, tighten the nut (for TL50 ~ TL89) or the bolts (for TL127 ~ TL178) gradually until the
torque limiter stops slipping. Always tighten (or loosen) the bolts equally. Try this adjustment several times to find the proper torque setting for the machine. For your guidance, the below chart shows the relation between the effective rotated angle and preset torque.
For precise torque setting, run-in of the torque limiter is recommended, for example, 500 revolution at 50 ~ 60 rpm with a rotated angle of 45 degrees of the adjustment nut or the bolts.
