10-pack of 623-2RS miniature deep-groove ball bearings for Polyformer and other compact motion assemblies that call for a 3x10x4mm sealed bearing.
Why use 623-2RS here
- 3mm ID x 10mm OD x 4mm width matches the standard 623 bearing size used in small printed motion assemblies.
- 2RS rubber seals on both sides help keep dust and plastic debris out while retaining lubricant.
- Sold as a 10-pack, enough for spares or small subassemblies without buying a full bulk lot.

Gotchas

- Photo shows a single bearing to show seal style; this listing is for a 10-pack.
