Inch Ball Bearing Bushing
XR Ball Bushing Bearing Products
Thomson XR Ball Bushing Bearing products offer:
• Five times the load capacity or 125 times the travel life
of conventional linear bearings. 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.
