When it comes to spindle bearings, you need to ensure that they are properly lubricated to maintain a film of lubricant between the bearing raceways and the rolling elements. Without proper lubrication, then the rolling elements will have direct contact with the raceways. This eventually results in heat, race deterioration, cage disintegration, rolling element deterioration, and spindle/bearing failure.
Unfortunately, some people do not understand how to go about with spindle bearing lubrication. If this sounds like you, then you’ve certainly come to the right place. Below are some of the things you need to know about spindle bearing lubrication.
Grease Lubrication
Grease packed spindles have gained immense popularity over the last couple of years. Even though most spindles are greased for life, there are those that do not require you to add grease. When you opt for spindles that are greased for life, you should keep in mind that the bearing life can decreased by the introduction of outside influences such as high heat, coolant, metal chips to name a few. To have an easy ride, be sure to understand the difference that exist between these two before jumping to conclusions.
Oil Lubrication
In most cases, oil lubrication is done by external equipment before being carried to the spindle via tubing. These systems happen to be liquid oil such as Mobil DTE light delivered to the spindle in a stream of air. However, there are a few different systems including oil mist andoil injection. Each of these systems has its own characteristics.
For instance,the oil injection system allows for high speed operation of the spindle while at the same time decreasing external environmental impact. This is possible since the oil is not delivered in atomized form and used oil can be collected. Oil mist systems, on the other hand, require little maintenance.
Final Thoughts
Understanding machine tool spindle bearing lubrication and how to properly lubricate your spindle bearings and maintain a healthy film between the rolling elements and raceways does not have to be stressful. Actually, you can leverage the internet in this regard and clear all your doubts in mind.
