All generations of minibuses have a side (sliding) door. Three rollers are responsible for the door operation, upper, middle and lower. They move along guide rails; for each generation of minibuses, the guides are different.

Structurally, a roller is a rolling bearing, in which the outer cage of the cage is made of plastic or metal. The plastic cover is used to reduce noise, but the life is reduced. The metal version of the outer cage of the separator is more durable. If the machine is a truck, the rollers are changed to metal ones, since there is no need to reduce the noise level of the sliding, but there is a need to increase the service life.
