Sufficient bearings life time is guaranteed
just with bearings specified in table 5.
These bearings are filled with special
grease that ensures appropriate life time.
Using other bearing types can lead to
shorter motor life time and Domel cannot
guarantee for these bearings.
Explanation of bearing designation:
6205 ZZ C3 E D EA3 S NSK
Bearing producer

C3
- 6202, 6203 (11-25
m)
6204, 6205, 6206 (13-28
m)
Bearing sealing
ZZ – shields on both sides
DDU – contact rubber seals on both sides
Bearing geometry number
Other data important for new bearing selection:
Consider ambient temperatures expected for motor operation (Motors are designed for
long term operation at temperatures from -40°C to +52°C).
Max. long term bearing operating temperature can reach 80°C
Grease viscosity must prevent grease leakage from bearing
