Ball Spline

The design of ISB Ball spline is to utilize the friction force through the contact of steel balls within in the Spline Nut and the grooves on the Spline Shaft.

With ISB’s unique 40° angular contact design which enables the Ball spline delivers high sensitivity and extreme high load carrying capacity.

The concept is optimal for the application involve with high speed, vibrates, impacts of loading and precise positioning requirements. Also when the Ball spline is used to function as linear bushing, the Ball spline provides ten times loading capacity than the linear bushing in the like dimensioned but with a compact profile. Built with durability and reliability, ISB Ball splines are suitable for all applications.

Spline Nut is available in two different designs: SLF (Flange design) and SLT (Non-flange design). Point of contacts on the Spline shaft is provided in two grooves (180°) (SLF/SLT6~20) and four grooves (70°) (SLF/SLT25~50) base on the diameter of the Spline shaft. Also ISB provides Hollow Spline shaft for alternative.
