NB Corporation of America High Load Linear Bushing TOPBALL® Series

The TOPBALL linear motion mechanism is a self-aligning high load capacity linear ball bushing incorporating many unique features that make it an excellent choice for a wide range of applications. TOPBALL linear ball bushings are often used in automated factory equipment and industrial machines, optical and measuring instruments, and any other application that requires precision, light weight and low cost. Self-aligning load plates To avoid problems caused by mounting or machining errors, or by shaft deflection, TOPBALL load plates feature tapered ends that compensate for slight misalignments. This ensures more accurate performance with fewer adjustments when installing the product. Floating seals A floating seal helps maintain alignment while also ensuring the TOPBALL load plate remains consistently in contact with the shaft. Best of all, this is done without affecting the shape or length of the bushing, making TOPBALL bearing and linear pillow blocks suitable for miniaturized designs. Adjustable clearance Configure the TOPBALL linear ball bushing bearing to the specific requirements of your application by using its adjustable load plates to set the desired clearance level between ball and shaft components. Together, these unique features provide TOPBALL linear pillow block bearings with many key benefits, including: Longer travel life Likewise, higher load capacities also translate to longer travel life. Compared to conventional linear ball bushings, TOPBALL products offer up to 27 times the travel life. Higher load capacity The precisely ground load plates allow TOPBALL to deliver rated capacity up to three times higher than conventional linear ball bushings. Higher speed TOPBALL is suitable for use in many high-speed applications, including systems moving at up to 3m/s.
