💡 What is a needle roller bearing used for in heavy machinery and how do seals and oil hole extend service life?

Needle roller bearings are handy for compact, high radial-load support in rotating shafts.

- high radial load support in tight spaces for compact machinery - sealed lubrication and oil hole reduce lubricant loss and wear - precise shaft alignment and smooth rotation in automated systems
