A PULLEY
A pulley is like an IRON pipe.
Pulleys are put on each end of the bed.

WHAT IS A BEARING?
When two pieces of steel touch each other; they

Bearings use little steel balls to keep the pulley shaft

HOW THE DRIVE PULLEY DOES THE WORK
The drive pulley is turned (driven) by a motor. A sprocket is put on the drive pulley
