5-1) Installation coupler
. When attaching a coupler, be careful not to apply impact force or excessive
thrust to the shaft ; otherwise, the bearing may be damaged.
. Shrink fit or shaft-end thread is recommended for mounting (Fig. 3)
The dimensions (A, B, and X) illustrated in Fig. 4 shall be within the tolerance
shown in Table 2.

6. Lubrication
6-1) Shipping condition
6-2) Method of lubrication
The oil splash lubrication method is used for PARAMAX SINGLE STAGE DRIVES SPA Series.
Under certain conditions, grease or forced lubrication should be used.
(1) Splash lubrication
(2) Forced lubrication
(3) Grease lubrication for bearings
Standard input shaft rotating speed range 450 1800r/min.
Grease lubrication will be required depending on an operating condition. In such case, the location and number of
grease nipples should be confirmed in advance. The bearings are packed with grease at the time of shipment.
Supply grease according to the input speed - every 1500 hours when the revolution is under 750r/min, and every
1000 hours when the revolution is 750-1800r/min.
6-3) Selection of lubricant
Refer to Table 3 to select mineral oil or synthetic oil.
Table 4 shows recommended lubricants.
. PARAMAX SINGLE STAGE DRIVES SPA Series units are shipped without oil. Supply recommended oil
before operation.
Table 3 Lubricant table
CAUTION
For a system in which a lubricant motor pump is provided separately, switch on the pump motor prior to
switching on the reducer motor. This will enable proper lubrication of the bearings prior to start up.
Failure to do so may damage the unit.
Use a flow switch and/or sight to verify that lubricant is circulating, and for emergency motor stop if necessary.
