This wheel with a large diameter of 200 mm is perfect for replacing very worn wheels in situations where the available axle lengths are very short. Indeed, the length is only 45 mm, which allows for many applications! Polyurethane has good resistance to mineral oils. The abrasion resistance of this type of PU is 38 mm3 in the ISO 4649 test, and the coefficient of friction is 0.20.
