How lubrication systems work

Advantages and disadvantages of different relubrication methods

Single point lubrication devices are operated with gas or electromechanically. They regularly give off grease or oil to rolling bearings, chains, guides and other machine components. Multipoint lubrication devices are centralized lubrication systems that can deliver grease to multiple lubrication points. The smaller motorized multipoint lubrication devices are limited to a certain number of lubrication points, but this can be an advantage over their much larger, centralized counterparts.

Both types ensure continuous lubrication over a certain period of time. But the multipoint lubrication device, whose lubricant chamber always provides immaculately pure lubricant, requires minimal maintenance compared to centralized systems and is an independent, stand-alone device. This means that the entire plant does not have to be shut down if only one system fails. Damage resulting from a lubrication problem is therefore less and maintenance costs are reduced. Multipoint lubrication devices are also very compact and a suitable solution when more than one type of lubricant is used in a system.

Depending on the selected product and the specific application requirements, the lubrication devices can work as short-term lubrication for up to many months. While some products are designed for one-time use, other devices can be refilled with replaceable lubricant cartridges and thus have a longer service life.
