The most common lubricants are grease and oil. Grease is made from oil and thickening agents. Additives are also added into lubricants, but the amount depends on their application. Engine oils can have dispersant added, which keeps insoluble matters grouped. During circulation, these insoluble conglomerated matters get removed.
On the other hand, a viscosity index improver can be added when the temperature goes from severe cold to hot. Additives are lengthy organic molecules, which stay grouped in cold temperatures and unravel during the heat environment. The oil’s viscosity gets adjusted and thus allows better flow in cold environment while maintaining high-temperature properties.
Lubricants are needed in machines, vehicles, and industries. Nboljor in Sweden stocks lubricant oil suitable for industrial and vehicle use. They offer biodegradable lubricants from recognized suppliers to customers around Sala and Vasteras. Technical support is offered to corporate customers and even the waste oil from their vehicles is taken care of.
Tips to choose the right lubricant
Before you shop for oil or lubricant, it is wise to gain awareness about the different types to make an informed buying decision.
Three common additives used in making oils are detergents, antioxidants, and corrosion inhibitors.
- Detergents prevent forming.
- Corrosion inhibitors prevent from corroding.
- Antioxidants prevent oil from oxidizing.
The long polymer chains cannot be squeezed easily, so oil is a helpful slippery barrier. Oils are available in different viscosity level like 5W or 10W. A lower number means thin oil, easy to flow. Oil lubricant has 95% base oil and 5% additives.
Oil is blended with some thickening agent. It may even contain particles like graphite, Teflon, Molybdenum disulfide. Oils lubricant properties and stickiness are included in greases so that it sticks to the surface in a better way. Grease protects the surface from contamination and damages. The drawback is that this greasy and thickness can trigger resistance in fast-moving or small engines and machines.
Lubricants made from silicon, PTFE, or graphite are great to reduce friction between the two surfaces. At molecule level, these particles are very slippery and the best lubricant agent between two surfaces. You can buy them in spray form. It is a mixture of water, alcohol or other solvents. When the sprayed solvent evaporates, there will be a thin layer of lubricant substance left.
The penetrating lubricant can help to loosen stubborn rust build-up. They are not meant for durable lubrication but are designed to infiltrate tiny cracks like within surfaces of threads and screws. Moreover, to break the rust as well as keep the region lubricated. Penetrating lubricants have low viscosity and are cheaper, but work efficiently in loosening a stuck bolt.
Factors that will influence lubricant selection
- Oil viscosity and application is the key factor to consider.
- Friction type like rolling or sliding
- Axis operating speed like fixed or variable
- Industry standards
Environmental and load conditions
Besides price per kilogram the other determining factor that needs to be considered are –
- Improved labor utilization [less time needed for maintenance and re-lubrication]
- Reduced operating costs due to less downtime
- Increased output and energy savings
