Single Line system is suitable for installation where the oil has a viscosity of less than 1500 CST. This system is suitable for every quick bearing and it can easily be extended, there is no expansion limit. This system is the most economical.

Progressive system is suitable for installation with few lubricating points and which must not be modified. Any oil viscosity can be pumped, and a physical control of the injection can be made.

Double Line + Air/Oil Progressive system is the most suitable for complete installation of wire, profile, plate mills, etc. It has certain advantages like – no extension limit, only one pumping group, no limit to the oil viscosity to be lubricated, provision for physical control of the injection and has dividers (special instruments, developed to distribute the oil in large-sized riders), normally used in plate mills, where oil has to be distributed from one inlet to several lubrication points of chock (axials, two radials, retainer).
