For lubricant base oil use, the vegetable derived materials are preferred. Common ones include high oleic canola oil, castor oil, palm oil, sunflower seed oil and rapeseed oil from vegetable, and tall oil from tree sources.

To lubricate each part of the bearing, and to reduce friction and wear. To carry away heat generated inside bearing due to friction and other causes. To cover rolling contact surface with the proper oil film in order to prolong bearing fatigue life. To prevent corrosion and contamination by dirt.

To create lube oils with different viscosities, heavy oil is distilled into various fractions and residues through a process known as vacuum distillation. These resulting fractions are categorized as fractional lube oils and residual lube oils, each serving different applications due to their varying viscosities.

In fact, most lubricants should be handled with care and proper personal protective equipment (PPE). The base oils and additives that make up lubricants not only can have catastrophic effects on the environment, but they can also be toxic to your health.
