Use a silicone or Teflon spray ONLY. DO NOT use grease, oil,lithium or WD 40. Grease and Lithium are thick type lubricants and are designed to be applied manually to flat or almost flat friction surfaces. Grease and Lithium can also attract dirt which can work its way into the mechanisms and cause wear. White Lithium Grease. Lithium Grease is that thick white grease you often find packed into bearing housings. It is the workhorse of the lubricants and can take high temperatures and pressures. If you have a grease housing which will hold extra grease, using a thick lithium grease. White Lithium Grease. Dielectric grease, on the other hand, is a waterproof grease that repels moisture out of a connection. Because it is non-conductive, it does not allow the flow of electrical current. It is silicone based, which makes it an effective barrier against moisture and salt precipitate.

Silicone Spray Vs White Lithium Grease
Why Use White Lithium Grease

Lucas gun oil works like a champ and doesn't gum up, that and a dab of silicone grease for the gear train once about every three months keeps my reels running smoothly and casting like a rocket. One word of caution; don't use anything in a spray can, the propellant is usually going to do some long range damage and at best, mess up the drag system.
Five common uses for synthetic silicone oil based lubricant grease. The uses of silicone lubricating grease are nearly endless, but here are five of the most common: Scuba gear and underwater devices. Divers use silicone grease to seal and protect dry suit gaskets. Spear-fisherman use it to protect their speargun rubbers and keep them supple.

Some engineers see lubricants as a straightforward, messy ancillary of the industrial age. However, much like rolling-element bearings themselves, lubrication is an ancient technology that’s highly engineered in modern forms. In fact, engineers have used fluids to reduce friction thousands of years, but the advent of the oil industry in the late 19th century spurred modern bearing lubrication. Today, bearing lubricants serve several functions:

Creating a barrier between rolling contact surfaces
Creating a barrier between sliding contact surfaces
Protecting surfaces from corrosion
Sealing against contaminants
Providing heat transference (in the case of oil lubricant)

Silicone Spray Vs White Lithium Grease

Lubricants take the form of either oil or grease. Oil lubricants are most common in high speed, high-temperature applications that need heat transfer away from working bearing surfaces. Bearing oils are either a natural mineral oil with additives to prevent rust and oxidation or a synthetic oil. In synthetic oils the base is usually polyalphaolefins (PAO), polyalkylene glycols (PAG) and esters. Although similar, synthetic and mineral oils offer different properties and are not interchangeable. Mineral oils are the more common of the two.

The most important characteristic when specifying oil for a bearing is viscosity. Viscosity is a measure of a fluid’s internal friction or resistance to flow. High-viscosity fluids are thicker like honey; low-viscosity fluids are thinner like water. Engineers express fluid resistance to flow in Saybolt Universal Seconds (SUS) and centistokes (mm2/sec, cSt). The difference in viscosity at different temperatures is the viscosity index (VI). An oil’s viscosity is correlative to the film thickness it can create. This thickness is crucial to the separation of the rolling and sliding elements in a bearing. Bearings in some applications use oil, but grease is the lubricant of choice for 80 to 90% of bearings.
Grease consists of about 85% mineral or synthetic oil with thickeners rounding out the rest of the grease volume.

The thickeners are usually lithium, calcium or sodium-based metallic soaps. Formulations for higher-temperature applications often include polyurea. The higher viscosity of grease helps contain it within the bearing envelope. The most important considerations when choosing a grease are the base oil viscosity, rust-inhibiting capabilities, operating temperature range and load-carrying capabilities.
