Today’s machine builder with a linear motion application is often not focused on finding the fastest, cheapest or highest load solution. What’s needed is the optimal balance of installed cost versus performance. Finding the right configuration of pillow block bearings and shafting can help.
Round rail pillow block bearings offer advantages over square rail guides such as: self-alignment and greater tolerance of reduced parallelism. Pillow block bearings can be installed with either continuous or end supports. They handle moment loads well; offer low drag and excellent smoothness. Pillow block bearings are, without doubt, easier and less expensive to install than square rail bearings without compromise to important performance requirements.
Thomson offers the world’s largest, most reliable offering of pillow block bearings including Super Smart, Super, Precision Steel, Multitrac, FluoroNyliner styles, enabling a huge range of cost-to-performance options. Pillow block bearings are available as complete assemblies or retrofit kits.
One new product in the line is the Lube for Life pillow block bearing which eliminates the need for regular bearing lubrication maintenance. Self-lubricating cartridges are pressed into each end of the pillow block bearing housing. They provide continuous bearing lubrication and enhanced protection for a broad range of applications.
The new Lube for Life polymer is also available in a food grade version, too, particularly appropriate for FluoroNyliner pillow block bearings running on new, lightweight, precision aluminum shafting available from Thomson.
Our pillow block bearings also promise a “just-right fit” thanks to the broadest standard product offering and our ability to do quick modified-standard and complete custom solutions. Reliable, fast delivery of pillow block bearings from Thomson also provides peace of mind once your new application is in the field. Contact Thomson customer support for a balanced evaluation of your application.
Thomson Lube for Life pillow block bearings provide continuous bearing lubrication and enhanced protection for a broad range of applications. Self-lubricating cartridges are pressed into each end of the pillow block housing, and the linear bearing is lubricated initially with EP2 grease. The Lube for Life polymer is under constant pressure against the 60 Case shafting, ensuring a film of lubricant between the ball bearings and the inner race. The Lube for Life pillow block bearing is available as a complete assembly, or in a retrofit kit for existing non self-lubricating pillow block assemblies.
Thomson pillow block bearings with factory-installed Super Metric Ball Bushing Bearings offer accelerations as high as 150 m/s2 and steady state travel speeds up to 3 m/s without the derating factors commonly required with linear guides, and the twin version with two Super Ball Bushing bearings provides twice the load capacity or 8 times more travel life than the single version.
Thomson pillow block bearings with Super Smart Ball Bushing® bearings offer advanced technology features, including up to 6 times the load capacity or 216 times the travel life of conventional linear bearings and permits the up-rating of existing designs. This high load capacity permits cost reduction through the use of smaller and less expensive bearings and 60 Case LinearRace® shafting.
Precision Steel Ball Bushing bearings offer great improvements in efficiency, productivity, and accuracy over high-friction plain bearings flat-ways. The all-steel design makes the bearing product line perfect for replacing plain bearings in high temperature applications. Rigid construction makes them very durable compared to ball bushing bearings with polymer components. When installed in a standard Thomson Pillow Block, the Precision Steel Ball Bushing bearing can self-align up to 3° in all directions.
