Tri Fidget Spinner - Fidget Toy with Hybrid Silicon Nitride Si3N4 Ceramic Bearing and ABS Frame - Anxiety, Stress Reducer (Black)
Description
- Silicon Nitride Ceramic Hybrid Bearing: Silicon nitride ball bearings are much harder than metal, this reduces contact with the bearing track. This reults in 80% less friction, 3 to 10 times longer lifetime, 80% higher speed, 60% less weight, the ability to operate with lubrication starvation, higher corrosion resistance and higher operation temperature, as compared to traditional metal bearings.
- Super Strong and Durable Frame: Made from high quality ABS, the frame is super strong and durable, you'll never have to worry about breaking your spinner. Plus, it's 100% safe to use.
- Great EDC Toy: The spinner can spin about 1 to 3 minutes, depending on the force you use. It's about 3 inchs wide and tall and weighting 0.11 lbs, quite small, lightweight and easy to carry around.
- The New Anxiety and Stress Reducer: Fidget toys is the cure for people with nervous or bored energy, it helps people quit nail-biting, leg shaking, desk-drumming, pen-clicking, etc
- 100% Satisfaction Guarantee: We offer 60 day warranty covering manufacturing and material defects. If you're not satisfied with your purchase for any reason, you will receive a full refund.
Explore the Amazing Collection of Fidget Spinners from Tonado-Spinners What's Ceramic Hybrid Bearing Ceramic hybrid bearings have steel races and ceramic balls. Ceramic balls are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually friction-less and capable of spinning faster than steel balls. What's Silicon Nitride Ceramic Silicon nitride is a chemical compound of the elements silicon and nitrogen, with the formula Si3N4. It is very hard (8.5 on the mohs scale). Silicon nitride ceramics have good shock resistance compared to other ceramics. Therefore, ball bearings made of silicon nitride ceramic are used in performance bearings. A representative example is use of silicon nitride bearings in the main engines of the NASA's Space Shuttle. 100% Satisfaction Guarantee We offer 60 day warranty covering manufacturing and material defects.
