Ball bearing guideway

steelprofiled rail

The compact design of Nook runner blocks offers greater design flexibility and several methods of mounting compared to other linear guidance systems. Special retainers and recirculation tubes prevent balls from escaping when the runner block is removed from the rail. (remove slowly with no-load) Features And Benefits Equal load carrying capacity in four directions Steel bearing balls recirculate between the rail and the runner block and contact both surfaces at a 45 angle. Equal load can be applied bi-directionally in both horizontal and vertical axes. The Nook System is also capable of withstanding moment loads. High Rigidity and High Moment Rigidity The benefits of full radius ball raceways are well established in the manufacture of precision ball screws. The circular shape provides ideal ball to ball raceway contact giving greater system rigidity. The precise geometry of the square configuration of the ball raceway is ideal for preloading and provides high system rigidity. A range of preloads are available depending upon the requirements for rigidity and load capacity. Preload is achieved by the selection of precisely graded ball diameter. The precise geometry of the square configuration of the ball raceway is ideal for preloading and provides high system rigidity.
