Part list
7.2 Bearing types for motor sizes
The general bearing types and sizes for the various motor
sizes and IE classes are shown in Table 2, Table 3, Table 5
and Table 6 for classes IE1 to IE4, respectively. Type 2Z and
2RS bearings or equivalent closed bearings are greased for
life. Always ensure that the shaft seals are intact. Note that
differences are possible between the bearing size and the
actual frame size.
Motors with re-greaseable bearings must be greased ac-
cording to Section 10.2 and the greasing data plate on the
motor. In case of doubt, contact Hoyer Motors.
