Good product, slow shipping
The bearings themselves are great, but packaging took a while to arrive. Product arrived safely though.

High quality but expensive
Performance is excellent for high RPM motors, but the price point is higher than competitors. Worth it for reliability.

Perfect for miniature robotics
Used these in a custom robotic arm joint. Smooth operation and very low friction. Genuine NMB quality is evident.
