2 Pack U626ZZ Ball Bearings For Linear Motion Slide Systems
✔️ 6x30x10mm Metric Chrome Steel Inner Ring Nylon Groove ZZ Type

You get a handy double set of shielded bearing sleeves built for steady sliding action across rails and tracks. The deep groove design accepts radial and axial loads while keeping friction low for smooth travel. Steel rings pair with resistant nylon grooves to handle wear without slowing performance.

✅ Inner diameter 6 mm fits shaft sizing.
✅ Outer diameter 30 mm provides structural spacing.
✅ Thickness measures 10 mm for compact assembly.
✅ Groove width 6 mm guides pulley wheels steadily.
✅ Groove depth 3 mm ensures secure track engagement.
✅ GCr15 steel core supports reliable load capacity.
✅ Nylon races minimize friction during operation.
✅ ABEC3 precision levels deliver stable slide performance.
✅ ZZ seals keep contaminants out while retaining lubricant.

💡 Why choose shielded bearing pulleys over open rollers for smooth sliding tasks?

You gain steady motion control and less upkeep when your rail system relies on pre-lubricated units sealed against dust. Here is how these handy builds keep your slides buttery smooth and trouble free.
- Deep groove designs catch radial and thrust loads without skewing alignment.
- Nylon grooves resist wear longer than metal paths under friction heat.
- ZZ seals trap grease inside while blocking grit from grinding parts.
- ABEC3 tolerances keep sliders rolling straight for exact positioning.
