O-ring (2) for Ball Winder Flange
This is the black o-ring that goes around the large circular section of the spindle. It needs to be replace whenever it shows sins of cracking or other damage or wear and tear. It acts like a tire on the unit so it sees more wear than any other component. However, it lasts and lasts as well. Typical replacement rate for a heavy user such as a yarn shop would be yearly. Knitter at home - every 2-4 years. A lot also depends on the dryness in your location. Dryness dries the rubber out more quickly. The other thing that causes wear and cracking is use how tightly you have it pressing against the steel shaft. The tighter, the more stress on the rubber, the more cracking.

QUESTIONS & ANSWERSAsk a Question
How do you put on the replacement 0-ring?
Hello and thanks for your question. In order to replace the flange O-ring on the spindle of the ball winder, you must remove the spindle from the ball winder. To do this, you loosen the 2 screws underneath the flange by loosening them 1/4 to 1/2 turn of the NUT DRIVER that was provided with the ball winder. This is a 5/16" nut driver. Alternatively, you can use a medium sized flat screwdriver but be careful not to strip the slots in the bolts.
Once you loosen the 2 screws simply pull up on the spindle until it is free of the ball winder.
Then pull the black oring off of the flange by "peeling" the oring out of the slot it is in.
Then position a new oring in it's place.
Then re-install the spindle on the ball winder.
CAUTION! you will need to adjust the tension against the oring properly. See our video
