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.

Apparently many fidget spinners use this specific bearing!

So... buy a cheap fidget spinner, get three or four China bearings in the bargain.

Thanks! This may well be the thing. Alternately, if someone wants to split Ed's pack of 4 with me, that'd be great as well.

Deep Space Products sell some very nice ceramic ball bearings for the CGE. I put some in mine after I found the same problem and they are very smooth. Be very careful when you adjust the end play because over tightening will cause the bearings to fail.

Stock Drive products has bearings that size too.

There have been a few CGE rebuild threads here ... they have been around for a while so when you search remember to include the archives. There's also an external PDF document on the rebuild (somewhere). They did list the types of bearings used.
