Safety
WARNING
Death or serious injury may result from misusing the product without following the directions given under this sign.
⚫
Before carrying out maintenance, make sure there is no load or turning force applied to the machine.
⚫ Inspect operation periodically for overloads.
⚫
Comply with Ordinance on Labor Safety and Hygiene 2-1-1 general standards.
⚫ Comply with this manual when conducting unit installation, removal, maintenance and inspection.
⚫ When using with lifting equipment, install a suitable protection device for safety purposes. Otherwise the equipment may occur due to a falling
accident.
Minor or moderate injury, as well as damage to the product may result from misusing the product without following
CAUTION
the directions given under this sign.
⚫
Read this manual throughly before servicing the unit, and handle the unit correctly.
⚫ Design the equipment so that it can tolerate load and rotational force when overloaded.
⚫ For the slip system, Torque Limiter may become high temperature by the friction heating. Please handle with care.
⚫
Mechanical parts may wear depending on the rotation speed and slipping time. Check the operation periodically, and for any mechanical failure,
contact TSUBAKIMOTO CHAIN.
⚫ This manual is an essential part of the unit, and it should remain with the unit at all times including when redistributed.
Note : Failure take heed of information labeled "CAUTION" may also lead to serious accidents depending on the situation.
1. Assembly of Torque Limier
Wipe off oil, rust and dirt from each part before assembling your Torque Limiter. Then, assemble as follows. Note that all units are assembled
with a single disk spring. An additional disk spring is packed separately for use as necessary.
※A spacer is inserted between the disk spring and the lock washer for TL200-1L,TL250-1L,TL350-1L.

2. Machining accuracy on center member

Machine the center member friction surface and bore at 3S～6S.in addition machine the bore diameter of the center member in accordance
with the dimensional tolerance in the catalog.

3. Run-in

Usually, run-in operations for the Torque Limiter are not necessary. If a stable slip torque is required, however, make sure to completely
hand-tighten the adjustable nut or bolts. Then tighten 60 °more and run or rotate the Torque Limiter approximately 500 revolutions. If the
rotation speed is high, run-in several times to reach 500 revolutions.

4. Torque setting

After installing the Torque Limiter to your machine, tighten the adjustable nut or bolts but not too tight. Then, test several times by gradually
tightening the bolts to find the appropriate tightening value. Correlation between the adjustable nut/bolts tightening value
illustrated below. Slip torques vary depending on the friction surface. Graphs only show rough figures, so test with a slightly weaker torque first,
then gradually tighten to find the appropriate torque suitable for your machine. This is the most practical way.
※ Tightening angle 0°in the above charts refer to a condition where a disk spring secured by hand-tightening the adjustable nut or bolts.
