How to Clean a Diabolo Bearing

A diabolo is a juggling prop made from two plastic or wood tops joined with an axle in the center. To manipulate the diabolo, jugglers place it on a string running between two sticks and use the sticks to move the diabolo along the string or toss it in the air. Good-quality diabolos should glide smoothly along the string. If the diabolo moves slowly or erratically, clean and lubricate the bearings to improve its performance.

Things You'll Need

Wrench or ratchet
Degreaser
Mineral oil
Small jar
Paper towel
Silicone or petroleum lubricant

Instructions

- 1
  Twist the two halves of the diabolo apart to reveal the bearing. You may need to use a wrench or ratchet to remove the nuts on the open ends of the diabolo. Place the washers, nuts and bolts in a safe place so you don't lose them later.
- 2
  Soak the bearing in a small jar filled with degreaser or mineral oil and swirl it briefly. Leave the bearing to soak for 5 minutes. Place the bearing on a paper towel to dry thoroughly before replacing it.
- 3
  Put the diabolo back together and use it normally. If the diabolo still has trouble moving, you can try adding lubricant. You will need to take the diabolo apart again to expose the bearing.
- 4
  Add a drop of lubricant to the bearing. For best results, use a lubricant labeled for use with yo-yos. Wait 5 minutes for the lubricant to sink in.
- 5
  Put the diabolo back together again and use it as normal. It should glide smoothly on the string. If necessary, add more lubricant until the diabolo functions properly.
