The roller has an aluminum core with a hexagonal bore and is coated with a black rubber compound of 70±5 ShA. The rubber is abrasion-resistant and may leave marks on the material.
The roller is suitable for installation in various Kölle machines. Kölle rollers 76-644 are also available as standard with a white rubber compound of 60±5 ShA and a gray rubber compound of 65±5 ShA.
It is also possible to have the old roller re-rubberized, which is a more economical option (please send us an inquiry).
