If your robot has to take a lot of abuse - landing hard on the wheels, dishing out huge weapon hits, etc. - these deep-groove ball bearings are what you need.
- Perfect for distributing forces into the frame and reducing friction and motor load.
- Use these to support motor shafts, weapon shafts, and other axles with one or two flanged ball bearings.
- A side flange allows fitting into panels without pushing through the hole.
- Available in a variety of metric and US sizes.
- MR63ZZ (non-flanged, note the MR vs MF) is available here as well. If you need to replace the bearing in your Bearing Block, this is the one to get.
Specifications:
- Chrome steel construction
- Double shielded (ZZ)
- Oiled for extended life and high RPM
- No knock-offs! We stock only FAG, NSK and other top bearing brands.
