The degree of pitch needed on a gravity conveyor will depend on several factors:
1. The type of conveyor, roller or skatewheel.
2. Are the bearings grease packed or lightly oiled?
(Grease packed bearings roll slower.)
3. The weight of the package.
4. The quality or firmness of the package bottom.
The chart at the right gives some idea of how much pitch is required on a gravity conveyor.
