Large diameter rubber rings

Wear-resistant large diameter rubber rings for mounting on rollers and allowing support of rubber tires with wave edges.

How do you read the table?

e.g. Ring 8650: 270-35-89: outer diameter-width-roller diameter. To see what maximum height of wave edge or driver is possible with this ring, take the outer diameter minus the inner diameter. Divide the balance by 2 and this is the space that is made possible with these rings to allow the wave edge or catch to run back.

So: 270 - 89 = 181 mm. Divided by 2 = 90.50 mm. The maximum height of the wave edge or driver is therefore 80 mm.
