However, with the exception of castor, the monounsaturated oils that are most valuable for lubricant and fuel applications are those such as canola (rapeseed), palm olein, olive, and sunflower, which are also in high demand for food.
If you're in a pinch, there are some skateboard bearing lube alternatives around the house that you can try such a motor oil or even cooking oil to lubricate your bearings. Solvents will eat away at the plastics inside the bearing, shortening the lifetime of your bearings.
Vegetable oils are all those oils that are derived from plant products like seeds, nuts and fruits. Mineral oils are petroleum based hydrocarbons that are derived by distillation of crude oil. These are usually by-products of crude oil refining process while extracting gasoline and other petroleum products.
It is nonreactive with virtually all construction plastics and with metals, and is a thick-ish grease which stays where it's put. A little dab'll do ya. Only trouble is you have to be able to apply it directly to the surface to be lubricated; it doesn't wick into crevices like an oil or spray lube.
It reduces the risk of metal-to-metal contact, which can lead to increased heat, result in oxidation and negatively affect the film strength. Whether they are enhancing, suppressing or imparting new properties to the base oil, additives play an important role in the lubrication of machinery.
Vegetable oils are mainly triacylglycerols (92–98%), polar lipids (phospholipids and galactolipids), monoacylglycerols, diacylglycerols, and minor amounts of free fatty acids and polyisoprenoids.
The most widely used vegetable oils in the lubricant sector are our monounsaturated oils, which combine good stability to oxidation and thermal degradation with liquidity at lower temperatures. For some higher temperature applications, lauric oils such as coconut or palm kernel may be used for optimal stability.
Can you use vegetable oil with non stick cookware? Yes, vegetable oils such as light olive oil and canola oil are popular choices when using nonstick cookware. Other ones are grapeseed oil, coconut oil, avocado oil, and sunflower oil.
Cooking OilsOil-based lubes — as in cooking oil — are often safe and are even some of the most natural choices you have. Costa recommends olive, grapeseed, and coconut oils. Oil-based lubricants should not be used with latex or rubber products (including condoms) because they can cause tearing and breakage.

According to AAK Kamani, vegetable oils are known to have numerous health benefits; primarily it is a major source of energy and a carrier of essential nutrients which are vital for growth and metabolism, protecting brain cells, reducing the risk of heart diseases, etc.
Its disadvantages are grease-life limitations and a limited cooling ability. Moreover, in some applications there is a risk of grease starvation, which leads to reduced lubricating films.
The unsaturated fats found in vegetable oils, when they're heated, tend to oxidize. In this form, they're more dangerous to body tissues and can trigger inflammation, a known risk factor for making blood-vessel plaques unstable enough to cause a heart attack.
Lubrication Knowledge Menu
- Poor self-healing properties.
- Poor heat dissipation.
- Higher coefficient of friction and wear than hydrodynamically lubricated bearings.
- Color associated with solids may be undesirable.
- Difficult if not impossible to feed into a lubrication system.
- Storage or service life is limited.
Benefits of synthetic oil are numerous:
- Better low- and high-temperature viscosity performance at service temperature extremes.
- Better viscosity index (VI).
- Better chemical and shear stability.
- Decreased evaporative loss.
- Resistance to oxidation, thermal breakdown, and oil sludge problems.
What Are Side Effects Associated with Using Mineral Oil?
- Lipid pneumonitis if ingested in reclined body position.
- Fecal incontinence.
- Intestinal malabsorption.
- Impaired absorption of fat-soluble vitamins.
- Rectal discharge of mineral oil.
- Anal itching and irritation.
- Abdominal cramps.
- Nausea.
Cons of Biodegradable Lubricants
- Lubricity so potent, friction modifiers must be added to reduce slippage in certain applications.
- Insufficient oxidative stability; oil must be treated or modified to ensure performance (which increase costs)
- Small amounts of water can cause serious foaming and degradation.
Vegetable hydraulic oils possess very good lubrication properties and high viscosity index (low temperature sensitivity of viscosity). The main disadvantage of vegetable hydraulic oils is their relatively low oxidation resistance.
Compared to mineral oils, vegetable oils in general possess high flash point, high viscosity index, high lubricity, low evaporative loss, are renewable, and are environmentally friendly. More research and legislation in favour of the use of vegetable oil lubricants is recommended.
Water is not a lubricant.
Many different substances can be used to lubricate a surface. Oil and grease are the most common. Grease is composed of oil and a thickening agent to obtain its consistency, while the oil is what actually lubricates. Oils can be synthetic, vegetable or mineral-based as well as a combination of these.
Animal fats and vegetable oils are regulated under 40 CFR 112, which has identical requirements for petroleum and non-petroleum oils. Petroleum oils, vegetable oils, and animal fats share common physical properties and produce similar environmental effects.
The term “oiliness†is defined as that property of lubricants by virtue of which one fluid gives lower coefficients of friction (generally at slow speeds or high loads) than another fluid of the same viscosity. Its importance under practical operating conditions is shown to be greater than is generally recognized.
VI improvers (also known as viscosity modifiers) are additives that increase the viscosity of the fluid throughout its useful temperature range. This article is meant to provide you with a better understanding of viscosity index improvers, what they are, what they do, and why they are important.
Explanation: Adhesiveness is the property of lubricating oil due to which the oil particles stick with the metal surfaces while oiliness is the property which enables oil to spread over and adhere to the surface of the bearing.
Therefore biodegradable synthetic lubricants used in environmentally sensitive areas have been extensively explored [4]. These are mineral oils, vegetable oils and synthetic lubricants. Synthetic lubricants have been used for many years and before their development vegetable oils were used as main lubricants.
