Do not load overweight on the shaft.
※
Do not put strong impact when insert a coupling into shaft.
※
Failure to follow this instruction may result in product damage.
※
Fix the unit or a coupling by a wrench under 0.15N.m of torque.
※
When you install this unit, if eccentricity and deection angle are larger,
it may shorten the life cycle of this unit.
※
For parallel misalignment, angular misalignment, end-play terms, refer to the "Glossary"
section of Technical Description.
※
For flexible coupling (ERB series) information, refer to ERB series section.
