Questions about this product
- What are these U-groove bearings actually used for?
- They roll along guide rails to keep linear motion smooth and on track. The deep U-groove seats on the rail so the carriage won't derail. People use them on CNC axes, 3D printer guides, and automated drawer slides.
- What size are they and how much load can they take?
- Each bearing is 6x30x13mm, listed as inner bore, outer diameter, and width. The dynamic load rating is 2.1 kN and the static rating is 1.0 kN. That covers most light to medium linear motion jobs without trouble.
- Do I need to grease or service these bearings?
- No. They ship as sealed 606ZZ bearings, pre-greased and shielded on both sides. The seals keep dust and grit out while holding the lubrication in. You just install them and run them, no re-greasing needed.
