Thomson ball bushings are used for providing support to linear motion shafts and feature polymer retainers & outer sleeves for delivering a quiet, smooth & low-friction linear motion (coefficient of friction as low as 0.001). They are integrated with self-aligning property for optimised load distribution between the ball tracks and ensuring continuous-duty motion of the shaft. These Super Ball Bushing bearings further provide a diametrical fit when installed on slightly out-of-round housings and offer 6 times the load capacity or 216 times the travel performance, as compared to Thomson conventional steel linear ball bushings. Choose from a wide range of these closed ball bushings available in 0.625 & 1.000 inch / 16mm bore diameters on Raptor Supplies.
