Roller vs Ball Guide

HYUNDAI SE2200L “Roller Guides” = Higher rigidity / Lower friction / Higher load capacity

HAAS ST20 Ball Guides = “Lower rigidity” / More friction / Less load capacity

Roller guide ways use cylidrical shapped rollers, also called cossed-roller bearing, instead of recirculating balls to increase the load capacity of the guideway by reducing deflection under load. Friction is reduced due to a consistant contact between the guideway surfaces.
