Sealed Replacement Bearing

Upgrade your motor with these double sealed bearings.

Our custom motors come with sealed bearings to ensure long life. However if you have an early (or competitive centrifuge) with a stock JL3405A motor it has only shielded bearings. These fail very quickly if you get any oil contamination on them.
