Hybrid Ceramic Bearings are the best choice for fidget spinners. They have stainless steel races (outer case and inner ring) and ball bearings made from Silicon Nitride (noted as Si3N4) or Zirconium Dioxide (noted as ZrO2).
What size bearings do fidget spinners use?
For the most part, 608 is the “size” used for fidget spinner bearings. The actual dimensions of a 608 bearing is 22mm total diameter, 8mm bore and 7mm width. The vast majority of plastic fidget spinners out there to buy — or 3D print yourself — accommodate 608 fidget spinner bearings.
What bearing spins the longest?
Japanese bearing company NSK has built the longest running fidget spinner at 12 minutes or more. The design uses small, high-precision balls and a weighty brass ring to ensure smooth spinning and maximum centrifugal force.
What are 608 bearings?
The standard inline skates bearings have the designation “608”. The “608” means that the bearings are from the 600 series, with a 8mm inner diameter (the width of the hole, i.e., internal bore).

What is ceramic bearing?
Ceramic bearings are comprised of ceramic rolling elements (balls) enclosed in a ferrous (typically steel) inner and outer race. Since these bearings are constructed from many materials, they often operate in hybrid capacities.
Why do fidget spinners have bearings in the arms?
Fidget spinners are essentially low-friction ball bearings. That’s it. When two objects press against one another, friction prevents them from sliding smoothly. Most fidget spinners have a ball bearing right in the center of the toy, which is what you’re holding as it spins.
What is the longest spinning fidget spinner?
The accomplishment, a team effort by employees at MinebeaMitsumi Inc., was won by Takayuki Ishikawa. The record-setting time: 24 minutes and 46.34 seconds.

How do you make a fidget spinner?
DIY fidget spinner Draw round your template twice onto card and cut the two shapes. Glue the two shapes together using a glue stick. Poke a hole in the centre of the shape using a pin. Make the hole bigger using the end of the scissors so that the toothpick fits loosely.
What does C3 bearing mean?
Internal clearance being C3 means that the bearing has room for expansion if needed between the races of the bearing, whilst holding the outer ring and moving the inner ring in a radial movement you will detect a little amount of play between the two rings. C3 means the bearing has more clearance than standard.
Is Abeec 7 or 9 better?
ABEC includes five tolerances classes: 1, 3, 5, 7, and 9 with 1 being the widest and 9 the tightest. Thus, bearings with a higher ABEC rating have tighter tolerances, and that means better precision, higher efficiency, and the potential to accommodate applications requiring high speeds.
What ABEC is best?
ABEC 1 is the most crude, the least precise, the most durable, and the cheapest. ABEC 3 is what most cheap complete skateboards come with, especially skateboards from China. ABEC 3 bearings work for most skateboarding, but won’t roll very smoothly or fast. ABEC 5 bearings are the norm in skateboarding.

Should you lubricate ceramic bearings?
No, full ceramic bearings can be run completely dry. They do not need lubrication to run. Ceramic is non-porous, unlike steel, as a result it is virtually frictionless.
What is a disadvantage of ceramic bearings?
Ceramic bearings have lower load capacities in comparison to metals and are sensitive to thermal shock. Thermal shock is when the temperature gradient within the material causes a differential expansion, which results in an internal stress. This stress can exceed the strength of the material thus forming a crack.
Are ceramic bearing worth it?
Faster, lighter, and more durable? According to research, a well-made ceramic bearing will roll faster, saving you energy and allowing faster cruising speeds compared to an equivalent steel bearing. This is because the properties of ceramic allow the creation of rounder, smoother bearings.
What type of bearings are used in fidget spinners?
Hybrid Ceramic Bearings are the best choice for fidget spinners. They have stainless steel races (outer case and inner ring) and ball bearings made from Silicon Nitride (noted as Si3N4) or Zirconium Dioxide (noted as ZrO2).
