Bearing issues Example Fan Bearings

[Member ModdIt]

We are surrounded by bearings, many of our devices are unable to function without them.

Case, miniature ball bearings here, very much aimed in hope of Helping translating team member
but will apply for others searching for often hard to locate parts.

The bearings needed are 4mm outer diameter and 1,5mm inner (axis hole) diameter, and 2mm
of height only and have seals. They are for a cooling fan.

Translating the bearing size to ISO gives me 1,5x4x2 not having the number and letter combination
usualy engraved somewher on the bearing.
A fan load is axial with radial component so I guess at deep groove bearing, a fan runs at high speeds
is slightly exposed to dust and dirt, is unlikely to be fully sealed.

Most Common type with given dimensions is 681X ZZ. Search in Ebay gives me a number of hits, the bearing
is commonly used in RC models.

In Germany a reputable dealer to contact preferably with the markings on the bearing if differing from above
would be Causemann Flugmodellbau. In other countrys ther are similar specialist shops.

I would ask that dealer as in RC models similar loads and RPM to a fan are common.

OT: if wanted I can likely help out PC hardware wise, you really help antiX with translations, will support
that best I can. Not sure if EMail can be read so here too.
