Uncoated Aluminum Fidget Spinner Bearing Cap, 1 Set
1 Set (2 caps + 1 set screw) Bearing Cap.
Bearing caps are precision machined from 6061-T6 aluminum and are striaght off the machine. The surface is slightly concave and grooved for an outstanding grip and feel. These are designed with a small step that rides on the inner race of the bearing to prevent contact with the outer race of the bearing while spinning, to keep your spins times at their peak.
Caps will fit most spinners that use industry standard 608 skate bearings.
