Product details

The AST Bearings 6203-2RS is a sealed ball bearing measuring 17 mm bore by 40 mm outside diameter by 12 mm wide. It is cataloged as a pool pump motor bearing and is one of the most common sizes in that work.

Reading the number

6203 is the bearing size, and the 2RS suffix marks it as sealed on both faces. Those seals are what matter in a pump motor: they keep the factory grease in for the life of the bearing and keep water and grit from working their way into the races. The same bearing appears in catalogs written both as 6203-2RS and as 62032RS.

Doing the job once

A motor carries a bearing at each end and they wear together. If a motor has started to howl or the shaft has developed play, replace both while it is apart rather than chasing the noisier one first. Check the dimensions against the bearing you pull out before ordering, since motor frames of similar size do not all use the same bearing.

Questions and answers

What people ask about this product, answered by our pool techs.

What size is this bearing?
17 mm bore, 40 mm outside diameter, 12 mm wide.
What does 2RS mean?
It is the standard bearing suffix for a unit sealed on both faces. The seals hold the grease in and keep water and grit out, which is what a bearing in a wet pump motor needs.
Is 62032RS the same as 6203-2RS?
Yes. It is the same bearing written with and without the hyphen.
Should I change both bearings in the motor?
As a rule yes. A motor has a bearing at each end, both have run the same hours in the same conditions, and pulling the motor apart twice for the sake of one bearing is wasted work.
