(Notes) 1. C in the Coupling column indicates direct coupling, and P indicates connection with pulley belt.
2. ZZ indicates a shielded ball bearing, and C3 indicates radial internal clearance (refer to Table 14-2).
3. The vertical type and flange type use direct coupling as a standard.
(4) Grease replenishment frequency and replacement frequency
Select the frequencies from Table 12 according to the bearing No. (BEARING) and No. of poles
indicated on the nameplate.
(The replenishment frequency is noted on the "Grease replenishment procedures" nameplate.)
When the specified number of times of replenishment is exceeded, disassemble the motor, clean
the oil supply and drain parts of bearings, and change all grease.
(5) Grease replenishment and initial greasing amount
(The grease amount is noted on the "Grease replenishment procedures" nameplate.)
