bearings for Sysmic S1?

Pablo - 20-9-2020 at 11:37 AM

I have had my buggy for a number of years, and have not been kind to it as far as conditions go. It's probably well overdue for replacement bearings.

I've got the wide turbine style aluminum wheels on the back of it and the narrower one on the front.

Any idea what size bearings to order and a good place to get them from?


Thanks, Paul

The bearing number should be stamped on the side. I think they are 6204rs.
Should be able to get them off Amazon.

I learned the hard way that it is more than just those four numbers and a suffix (I.e. -2RS where it is 2 rubber seals).

Make sure to get the right outside diameter (measure the rim) and inside diameter (measure the bearing or know that it was a 20mm bolt installed). Both are typically in mm.

I replaced all my bearings this summer. I went by the number and missed the 5/8" so I have 10 bearings that are 15mm, not 5/8". Oops. This is for my land sailer...not siesmic rims!

What I bought for my Siesmic rims was 6004-2RS (notice this is different from what Cheezy has):

42mm O.D.
20mm I.D
12mm thickness

But again...measure yours.

To remove bearings there is typically an indent in the internal spacer...or move the spacer to the side and hit the back of one bearing to remove. To install...use the axle bolt with 2 large washers that push in the steel part of the bearings (ie don't push on the rubber seal!).

P.s. search for my post on the Ivanpah buggy and you will see the pile of Old bearings.
