Concave Bearing

Shielded size C concave bearing, 10 ball - wide bearing for unresponsive yoyos.

Fits most modern day unresponsive yoyos such as YoYoFactory Shutter, Replay Pro, MagicYoYo N12, Y01 Node, Y03 Hertz. If bearings start to become noisy, yoyo lubricant is recommended to keep it spinning quietly!

Note: bearings are moving parts and will eventually require maintenance/cleaning - soak in lighter fluid/isopropyl alcohol to loosen up dirt. Avoid exposure to sudden temperature changes and minimize opening the yoyo (so that dirt & string fluff doesn't get in). Clean string will also improve bearing life.
