💡 What is a needle roller bearing used for in linear slide unit assemblies? Needle roller bearings are handy when you need big radial capacity in a slim package. - Supports high radial loads in compact linear slide unit designs, saving space - Good alternative when a sealed ball bearing can't meet low cross-section or load needs - Oil hole and open caged design make relubrication easy for longer life
