Resistance Oil Lubricators operate on the principle of flow resistance within the lubrication line. In this centralized lubrication design, the amount of oil delivered to each lubrication point is regulated by the Manifold Blocks (also known as Manifold Distributors) . It is recommended to use Manifold Blocks with proportion adapters or oil meter adapters; users can achieve balanced oil distribution across multiple lubrication points. This system is suitable for machines that do not require precise oil volume to each lubrication point.
