ROUNDWAY LINEAR ROLLER BEARINGS

Roundway Bearings are patented, self-aligning linear roller bearings with load capacities up to 24,000 lbf and travel speeds up to 100 ft/sec. They offer exceptional performance in highly contaminated environments in addition to the following features:

• Up to twenty times the load capacity of conventional linear ball bearings. This dramatic increase allows for more compact machine designs with a reduction in hardware costs.
• A rigid design that provides high accuracy while tolerating the high shock loads common to machine tool application
• A coefficient of friction as low as .005. When replacing v-ways or flat-ways, RoundWay linear roller bearings allow for the use of smaller less expensive drives, motors, belts, gears and ball screws.
• A self-aligning capability that reduces installation time and cost
• An eccentric trunnion pin that adjusts bearing height to compensate for minor inaccuracies in mounting base flatness or machining accuracy. Installation is quicker and easier than older, more conventional systems.
• Availability of an integral wiper that protects against contamination while retaining lubrication
• Interchangeable components for quick, cost-effective machine maintenance
• There is no need to scrap the entire way system, a problem with some linear guide products
• The RoundRail* Advantage combined with the self aligning feature, eliminates the need for derating factors commonly seen with linear guides
