Slideway oils have been specifically developed for the lubrication of table ways in order to prevent stick/slip and jerky motion. They are blends of high quality base oils containing a tackiness additive and other special additives which prevent stick/slip. The oil is applied either manually or through central systems and is lost after use. Horizontal slideways are often lubricated with ISO VG 68 slideway oils. Inclined or vertical slideways are lubricated with ISO VG 220 oils.
