6. ZCA can be installed in vertical, horizontal, or hanging application. For installation in horizontal and hanging
applications, the unit may be damaged if the unit is used while the bolts are under the weight of the ZCA or
additional loads. Ensure that the ZCA is placed in such a manner that the mounting bolts are not subjected
to load. (Fig. 2)

7. When installing a motor, reducer and ZCA, provide a highly rigid cradle to ensure centering accuracy even
under maximum loads. Be sure to align the input shaft and transmission shaft to avoid risk of damage to the
shaft. Tsubaki recommends its line-up of couplings for connecting the shaft.

8. The holes in the housing section are used to affix both sides of the housing section together (snap-fit
construction). There are no bolts for these holes. Do not use these holes to mount the unit, as they lack the
strength to hold the unit and may break prematurely. Use only the mounting holes provided on the drive
section.
9. When the ZCA is driven by a floating shaft, vibration may occur depending on RPM, which may lead to
operational errors. To prevent this, pay close attention to shaft stiffness and coupling backlash.
10. When attaching a chain, gear, or tooth/V belt to the input shaft for drive, verify that any overhang load
applied to the shaft falls below the allowable load.
11. When using synchronized ZCAs, there will be individual difference in backlash, resulting in some
mis-positioning. Be sure to install a separate mechanism to adjust phase by using a coupling with clamp
type, or shim to adjust the height. If the load is not properly balanced, it may cause damage to a unit by
operational load exceeding the basic capacity per unit.
