8mm Thrust Bearing

This precision 8mm thrust bearing design is engineered for versatility and ease of use. The ball holder features a slight flex when printed in PLA, ensuring a satisfying snap-in feel. Thrust bearings like this one offer exceptional load resistance and low friction.

This design includes two optional covers for enclosing the bearing, but the ball cage bracket can also be used independently. It rolls smoothly along flat surfaces, providing a uniquely satisfying experience. Perfect for applications such as fidget spinners, lazy susans, or game pieces requiring smooth 360-degree gliding movements, this model inspires creativity and empowers your imagination.

The covers are secured using the two-part central pin and 3x8 screw. The screw enables micro tension adjustments to modify spin movement.
