Uxcell MR126 2RS Groove Bearings Double Power Transmission Products Review

Using these BEARINGS our team found that they were incredibly smooth and durable. We were able to power through heavy loads with ease, and the noise level was noticeably lower than with other bearings we've used in the past. The only downside was that the initial cost was slightly higher than other options, but the long-term reliability of these bearings outweighs that con .Overall, we highly recommend these bearings for any power transmission needs..

These are bearings. They are sealed on both sides and roll smoothly. Don't make yourself a sandwich and don't read yourself bedtime stories.
