  • Rotery Table oil

    I have a Bridgeport 15" Rotary table.
    What is the recomended type and quainty of oil for the resavor?

      It is probably not real critical and almost any oil would work. The RT is a very slow moving mechanism and usually has a very light load unless you are using it to make a circular cut.

      That being said, I used a gear case oil that I purchased from a local auto parts store. It was no more expensive than motor oil and if it is good enough for auto service, it is more than OK for a RT.

      Make it fit.

        watch what you use ..don't use EP oil as it may have brass or bronze inside it as bushings or bearings .

        the EP stuff is the real stinky stuff ..if the oil you use stinks ..don't use it .

        all the best.markj

          Q: I heard that EP additives are corrosive to yellow metals such as brass and bronze. Is this true?
          A: In some circumstances, this can by true. Certain types of EP additives are designed to react with metal surfaces under elevated temperatures to protect them under boundary lubrication conditions. These types of additives are often referred to as “chemically active”, and at elevated temperatures (greater than 140 to 150 F), they can indeed start to react with yellow metals. For this reason, apply caution when selecting gear oils for worm drives; the ring gear is often a yellow metal alloy.

          A good way to check to see if an oil is “chemically active” is to look at the specification sheet provided by the lubricant manufacturer. On the sheet, you will typically see a test referred to as “copper strip corrosion” (ASTM D130). This tests how chemically reactive an oil is to copper and copper-containing alloys. For gear oils, a 1a rating is typically a good indicator that the oil is chemically inert, while higher ratings (such as 1b or 2a) might indicate possible problems when used in certain gearing at elevated operating temperatures. Often, a lubricant manufacturer will specifically state “this oil should not be used in gearboxes containing yellow metals”; other times, the manufacturer will simply state that the oil is appropriate for “steel-on-steel” applications – the implication being that they should not be used in situations where the ring gear is brass or bronze.
