Ball Bearings NH: 5 Questions We Get Asked Weekly

Somewhere between five and ten times a week, someone from around the state calls or emails asking almost the exact same set of questions about ball bearings in NH. So instead of answering them one at a time, we figured it made more sense to put the answers in one place.

“What size ball bearing do I actually need?”

Honestly, this is the one that trips people up the most. Most ball bearings have a code stamped right on the shield — something like 608ZZ or 6203-2RS — and that code tells you almost everything: inner diameter, outer diameter, and width. If the stamp has worn off, which happens more often than you’d expect on older equipment, measure the three dimensions directly and we can usually match it from there.

“Can I buy just one, or do I have to order a pack of ten?”

You can buy one. This comes up constantly with people doing a single repair — a skateboard wheel, a garage fan, a piece of shop equipment — who don’t need or want nine spares sitting in a drawer. We sell ball bearings individually as well as in bulk packs for shops that go through more volume.

“Do you actually ship to my part of New Hampshire?”

Yes. We’re based in Nashua, but we ship ball bearings across the whole state — up through Manchester and Concord, and out to the towns in between. Most orders within New Hampshire move within a day or two of processing.

“What’s the difference between shielded and sealed?”

A shielded bearing (marked ZZ) keeps out larger debris but isn’t fully sealed against moisture or fine dust. A sealed bearing (marked 2RS) has rubber seals on both sides and holds up better in wetter or dirtier conditions — think outdoor equipment or bicycle hubs — though it can spin with slightly more resistance. Which one you want really depends on the application.

“Why does one listing cost half what another does for the same size?”

This is worth asking about directly rather than assuming the cheaper one is just a better deal. Some ball bearings are resold through two or three distributors before reaching a marketplace listing, and tolerance class can vary more than people realize even within bearings that look identical. Buying from a supplier who sources directly from manufacturers tends to avoid that guesswork entirely.

Where This Leaves You

If you’re anywhere in New Hampshire and need ball bearings — whether it’s a single replacement part or a standing order for a shop — we’re set up to handle both. We buy directly from manufacturers, which keeps specs consistent, and our Nashua location means most of the state gets fast shipping without waiting on an out-of-state warehouse. For a deeper look at why tolerance class affects performance this much, ISO’s bearing tolerance standards are worth a skim.
