    It’s a cartridge bearing that only half exited. 😉

    Looking at replacement headsets, what is a ‘semi-cartridge’ bearing? I understand what is meant by a cartridge bearing, but semi-cartridge?

    A cartridge bearing that’s not fully hardened 😆

    I think that its marketing-speak for caged bearings, also called a retainer.

    Could mean a few things, cartridge bearing lower with cup & cone upper,or a pre-assembled cup & cone assembly that’s held together with a circlip so it looks like a cartridge, or maybe mrketing speak for a poor quality, barely sealed cartridge that’s not really up to the job.

    Hmmm, lots of good supposition, short on definitive facts. Anyone able to put this to bed?

    Impossible to answer really without context. I suspect it’s a component with 2 bearings, one cartridge one not , but who knows?

    Bottom bearing cartridge, top one caged perhaps?

    As suggested above by JoeG, for a headset I’d reckon it’s probably some kind of caged bearing setup – eg very much like a sealed bearing in effect but not actually one.

    OK, yes I know it’s marketing speak. So is ‘cartridge’ bearing. But we all know what they are referring to as a cartridge bearing. So, semi-cartridge bearing is a marketing term for what exactly?

    It isn’t a headset with one cartridge and one loose or caged ball either, because FSA who sell a headset with semi-cartridge bearings, also sells headset with cartridge bottom bearing and caged ball top bearing.

    I’ve posted a question with Wiggle.

    Whatever it is I’d probably avoid it anyway

    Oh I wasn’t in the market for one, just curious.

    From Wiggle:

    I can confirm that on a Semi-cartridge bearing the seals are open at sides for servicing. I hope this helps.

    If the seals are open, then surely they aren’t seals? 🙄
