1. A lubrication system for an apparatus including a rolling component, the lubrication system comprising:
a fluid reservoir containing a fluid;
a fluid line coupled to the fluid reservoir; and
a lubricating tube disposed between the fluid line and the rolling component, the lubricating tube comprising:
a rigid cylindrical body surrounding a cavity and having an outer circumferential surface,
an inlet coupled to the fluid line and providing fluid communication between the fluid line and the cavity, and
a plurality of ports disposed on the outer circumferential surface and configured to dispense the fluid to the rolling component, wherein a location of each port of the plurality of ports from the inlet is customizable; and
wherein the lubricating tube further comprises a plurality of holes disposed along the outer circumferential surface, wherein each hole of the plurality of holes extends from the outer circumferential surface toward the cavity, wherein the plurality of holes comprise:
a plurality of blind holes extending from the outer circumferential surface to a closed end, and
the plurality of ports, wherein each port of the plurality of ports is defined by one hole of the plurality of holes, and wherein each port of the plurality of ports extends from the outer circumferential surface to the cavity.
