The fact that solid lubricants can offer adequate lubrication under extreme conditions may leave you wondering, “What is solid lubricant?” Well, any lubricant helps to reduce friction and wear between two moving parts rubbing against one another. However, solid lubricants provide more functionalities and benefits to moving machine parts.

Solid lubrication is commonly used in bearing parts due to its unique properties. It helps to increase bearing longevity, reduce maintenance needs, and reduce oil loss from washouts. However, different solid lubricants, including graphite and molybdenum disulfide solid lubricants, have distinct properties that we’ll look at.

Let’s find out what a solid lubricant is, how it works, and when to use it.

What is it?

A solid lubricant has lamellar structures that prevent direct contact between two surfaces in contact even in extreme conditions. So, you can use it as an additive in oils and grease. Also, when manufacturing the components, you can allot or add them to the surface. Graphite and molybdenum disulfide are great examples of solid lubricants. 

How Does it Work?

A solid lubricant can mold quickly into a bearing cavity, as it’s a polymer material. It has numerous micro-pores that contain oil. So, the oil gets released as the bearing structure operates. However, the pores will reabsorb the oil when the bearing rests. Notably, a bearing can contain all the oil it will need for its lifespan within the micropores.

When is it Used?

A solid lubricant is an excellent solution for complex applications, including the ones subject to heavy contamination and parts in hard-to-reach locations. You can also use it in applications involving frequent washdowns. Other applications of a solid lubricant are:

  • Solid Lubricant and Washdowns: Applications that require regular washdowns with cleaners or water needs solid lubrication to reduce bearing failure.
  • Solid Lubricant and Agricultural Practices: Solid lubrication can be effective in the agricultural industry by protecting the rolling elements as a secondary sealing system and eliminating the need for bearing relubrication.
  • Reduce Bearing Maintenance: Since many bearing structures are in hard-to-reach places, regular regreasing can be tiresome. Thankfully, a solid lubricant eliminates the need to lubricate the bearing structures frequently.

You may not have heard about all types of lubrication systems. However, you know the function of lubricants: reducing friction between moving parts rubbing or sliding against one another. But for the oil lubricant to work efficiently, it must circulate in the lubrication system.

What are some different types of lubrication systems?

Oil lubricants are vital in enhancing the performance of machine parts. Besides reducing friction, they can act as a coolant to prevent thermal expansion between machine components.

However, there are different types of lubrication systems, including:

  1. Lubrication Pump
  2. Single Line Resistance 
  3. Single Point 
  4. Dual Line
  5. Grease Gun

1) Lubrication Pump

A lubrication pump comes with a built-in metering device and reservoir to help supply lubrication to the vital parts of a machine. You can readily connect it to the machine’s supply and feed lines. However, the pump has a relatively lower lubricant capacity to supply small lubricant volumes.

2) Single Line Resistance

This lubrication system comprises a central pump that supplies a lubricant to single or multiple supply lines that are parallel to one another (multi-line systems). Single-line resistance is a low-pressure lubrication system that works in light and medium machinery. It can dispense a lubricant to 100 lubrication points.

3) Single Point

As the name suggests, a single-point (SP) lubrication system distributes a lubricant to one lubrication point. Therefore, this system is effective when a few lubrication points are in a wide area. Besides, the SP system is automatic and comes in compact sizes comprising a small reservoir tank, metering devices, and feed lines.

4) Dual Line

The lubrication systems operate in two alternating cycles. In the first cycle, the lubricant gets pumped to the supply line from the reservoir. It will then move the injectors’ inlet and discharge pistons in one direction, including the lubricant. Notably, the injectors’ arrangement allows them to be shared by two supply lines. Once the preset pressure is achieved, the system will relieve the first supply line and pump the lubricant to the second supply line.

5) Grease Gun

Grease guns help to dispense grease to lubrication points in a machine and are ideal for maintaining equipment and machinery in industrial plants. First, however, you must add the lubricant to an enclosed canister and load it on the gun. Then, depending on your grease gun’s design, you can dispense the lubricant manually, pneumatically, or electrically.
