Roller chain consists of a series of connecting traveling metallic bearings, which must be properly lubricated to obtain the maximum service life of the chain. Although many slow speed drives operate successfully with little or no lubrication beyond the initial factory lubrication, proper lubrication will greatly extend the useful life of every chain drive. The chain drive requires lubrication for six purposes.

1. To resist wear of the pin-bushing joint.  
2. To cushion impact loads.  
3. To dissipate any heat generated.  
4. To flush away foreign materials.  
5. To lubricate chain-sprocket contact surfaces.  
6. To retard rust or corrosion.  

A good grade of clean petroleum oil without additives, free flowing at the prevailing temperatures, should be used. Some additives leave a varnish or gum deposit which prevents the oil from entering chain joints. Heavy oils and greases are generally too stiff to enter the chain joints and should not be used.  

Synthetic lubricants provide better protection with an increase in the following features:

Anti-Wear Additives ● Adhesive/Cohesive Additives ● Corrosion Inhibitors ● Superior Thermal Stability

Oxidation Inhibitors ● Friction Reducers ● Rust Preventatives ● Reduced drag

With proper lubrication, a separating wedge of lubrication is formed between the pins and bushings in the chain joints much like that formed in journal bearings. The viscosity of the lubricant greatly affects its film strength, and its ability to separate moving parts. The highest viscosity oil which will flow between the chain link plates and fill the pin-bushing areas will provide the best wear life. This is essential to minimize metal to metal contact and, if supplied in sufficient volume, the lubricant also provides effective cooling and impact dampening at higher speeds.  

Chain drives should be protected from abrasive and corrosive conditions, and the oil supply kept free of contamination. Periodic oil change is desirable.
