It also helps in reaching the lubricant into the bearing clearance to maintain an oil film and it avoids the direct contact with rolling elements and races. Here in this work an attempt is made to enhance the performance of taper roller bearing of Cold Rolling Mill by implementing Air- Oil Lubrication system.
5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.

plant and mechanical engineering applications. In steel and aluminium mills for example, this method of lubrication is beeing used on continuous casting plants, cold and hot strip mills and various types of rolling mills. Spray Lubrication Systems (view System description)
A rolling contact bearing is also known as the antifriction bearing. However, this is misnaming because there is always friction between the rolling element and the inner and outer cages. Depending upon the type of rolling element, bearings are classified as Ball bearing, Cylindrical roller bearing, Taper roller bearing, and Needle bearing.

Four High Rolling Mill: These machine consist four rollers (two small and two big). These rollers are arranged as shown in figure. Small rollers are in direct contact with work piece and rotate in opposite direction. Big rollers works as backup rolls and they also rotates in opposite direction with each other and also with contact roller.
There are three-roller present, a Drive Roller, an Idler roller, and an Axial roller in this type of Rolling. The two main rollers (Drive roller and Idler roller) rotate in the same direction. The Idler roller rotates Inside the Metal, and with the Increase in hole diameter, the rollers move closer to each Other. Image Source (iv) Tube Piercing:
