Roller Guide Evolution: How Needle Rollers Are Improving Linear Bearing Performance


The demand for higher performing roller guides is increasing. This 20-minute Tech Talk discusses the evolution of roller guides and then examines how needle rollers and the latest innovative technology are incorporated into a new-generation design that integrates ultra-high rigidity, motion accuracy, and damping capability.

The design achieves 1.5 times higher rigidity than conventional roller guides, reduces rolling element passage vibration to less than half, and improves vibration damping by more than 1.5 times. The presentation also shows how multiple rollers allow load to be dispersed and how longer roller length increases the contact surface between the roller and block/rail, reducing contact pressure.
