CGE worm bearing - source?
« on: December 27, 2017, 10:21:01 AM »
I have a CGE that has lately been making tortured noises when slewing in RA. I initially suspected the worm/RA-gear interface but removing the motor entirely and running at speed 9 makes it emit those noises. I took out one spur gear and voila! the worm turns as if lubricated by sand. Looks like the bearings are shot.

I was looking up the bearing named in this post:

But I couldn't locate an ABEC-7 version ofSSRI814ZZ. At most it's ABEC-3. I know that Deep Space Products sells a replacement pack of 4 for $50 but I need at most 2. Anyone know a source?

Tanveer.

ABEC5, but its more than enough considering the slow rotation of the worm shaft.

i bet the lowest ABEC Timken bearing will be better than a China bearing. there's this youtube video of a German bearing vs a China bearing. suffice it to say that ABEC ratings mean nothing with China bearings.

Now if only I could find 4 other people in the same predicament to share the cost. They want $90 for a pack of 10.

Dynaroll is supposedly based in LA. Don't know if the bearings are made in USA, or they are just a China importer.
