Thread: Are ball bearings standardized?

  1. #1

    Are ball bearings standardized?

    My front wheel bearings are starting to make a knocking noise, Im pretty sure theyre about to fall off.

    Can I just buy any new bearings, like the kind they use on skateboards and inline skates? Which kind should I buy?

    If you post what chair, front wheels you have, someone on here will be able to tell you what size bearings to buy and where to get them.

    But I'm guessing it's just loose if it's making a knocking noise.

    And I guess to answer your question, yes you can buy new bearing. Sportaid, Spinlife... They're both good

    What they ^ said, and this thread should be interesting to you.

    I'm referring to the wheel bearings. It's a KI Mobility Catalyst 5 chair. I have no idea what brand the front wheels are, whatever comes standard with the chair.

    Should I get a certain type of bearing? I was reading up on the ABEC standard, but I don't know what is best for front wheels on a wheelchair?
