History

 

Sliding doors were used as early as the first century CE in Roman houses as evidence by archaeological finds in Pompeii, Italy.

Sliding door gear

The mechanism used to operate a sliding door is called sliding door gear. There are two standard types, top hung or bottom rolling systems.

Bottom rolling door gear

Sometimes a top hung system cannot be used, as the weight of the door cannot be supported from above; in this case a bottom rolling system is recommended

A bottom rolling system consists of two rollers at the bottom of the door running on a track and two guides at the top running in a guide channel. As all the weight of the door is concentrated on the two bottom wheels, more force is needed to move the door than on a top hung system.
