Shafts with ball splines optimize the linear bearing function for high rigidity and precision.
The shaft with ball spline uses the sliding of the balls of the nut in the grooves of the shaft, with oblique contact at 40°, allowing a high flow and a very high load capacity. This design optimizes its behavior in applications with high speeds, vibrations and shocks due to the applied load, accompanied by accurate positioning precision.
Even when used with pure linear bearing functions, it guarantees a load capacity up to 10 times greater than bearings for linear motion in the same size, with a smaller footprint. In essence, reliability and durability are the reasons for choosing shafts with anti-rotation sleeve.
We supply grooved shafts cut to size or machined to customer specifications.
