What is a gravity roller?
A gravity roller conveyor lets a product move on rollers using the force of gravity to move the load. Gravity conveyors are one of the simplest and affordable types of material handling systems. They work by allowing the product to roll along the upper surface.
Gravity roller conveyors are some of the most commonly used conveyors in factories and other industrial settings. They offer a simple, reliable, inexpensive solution for transporting parts, products, and packages.

Features of conveyor roller
a. The precision ball bearing is fixed by impact in the steel housing, tight and durable.
b. The tight steel bearing unit could bear more axial force than plastic bearing unit.
c. Make it possible for the roller to work in the high or low termperature beyond the plastic part bear( e.g. oven or cold storage)
d. Completer series of diameter, wide range of load capacity.
e. Much louder noise.
g. Temperature range: -10 to +80 centigrade degree.

Advantage of gravity conveyor roller:
Zinc-plated is the most popolar suface treatment. The surface is electroplated through electrolysis, resulted in the rustproof in a certain extent.
1. Trivalent chromium blue-white zinc-plated, conformed to the requirement fo environmental protection. Special sealing process make our zinc-plated much more rustproof than common one, especially in the salt spray testing.
2. The suitalge thickness of zinc layer for roller is 8-12μm. If zinc layer is too thin, the rustproof capacity is lowered greatly; but if took thick, the zinc lay is easy spalling, and it brings meaningless cost increase.
3. The rustproof capacity of zinc-plated is limited. It will decay quickly in the moist and acid-base environment. In the case of roller shipment by sea, specially packing for shipment by sea is still needed.
4. Zinc-plated is not of strong abrasion resistance. It will fray gradually in the operation. If needed, you could choose the hard chrome plating or other surface treatment.
5. Food is not allowed to contact directly with zinc-plated surface.
