What to look for when choosing the castors you need ---About Materials 2022-04-08
Caster is a generic term that includes movable castors and fixed castors. The movable castor is what we call a universal wheel, which has a structure that allows 360 degrees of rotation; the fixed castor has no rotating structure and cannot be turned. Usually the two types of castors are used in combination, for example the structure of a trolley has two fixed wheels at the front and two movable universal wheels at the back near the pushing armrest. The movable castors will have a corresponding brake model. The material of castors is mainly divided into TPR super artificial rubber castors, PU polyurethane castors, PP nylon castors and ER natural rubber castors.
