This dramatic increase in travel life reduces downtime and maximizes productivity. • Three times the rigidity of conventional linear bearings. This increase in stiffness provides immediate improvements in machine positioning accuracy and repeatability. • The RoundRail Advantage combined with travel speeds up to 5 ft/s. Derating factors commonly found in linear guide products are eliminated. • Ease of maintenance. When normal maintenance requires bearing replacement, XR Ball Bushing Bearings can be quickly and cost-effectively replaced without scrapping the entire system – another shortcoming of some linear guides. • Double acting seals at both ends that keep out contamination and retain lubrication. • Lasting precision alignment by combining the nonwear characteristics of the XR Ball Bushing Bearing with a rigid ductile iron pillow block. • High accelerations and operating speeds without a dramatic increase in the power consumption commonly seen with high friction v-way and flat-way systems.
