Overview - ISO 23848-2:2009 (Ball splines, load ratings & rating life)

ISO 23848-2:2009 specifies how to calculate basic dynamic load ratings, basic static load ratings, and basic rating life for machine-tool ball splines (types AI, AII and R). The part also establishes basic dynamic and static torque ratings and defines key terms such as the L10 (90 % reliability) rating life. This standard supports consistent design, selection and life prediction for ball splines used where axial translation and torque transmission are required.

Key topics and technical requirements

Scope and definitions: Clear definitions for basic dynamic load rating (C), basic static load rating (C0), basic dynamic/static torque ratings (CT, C0T), dynamic/static equivalent loads and L10 life (90 % survival probability).

Calculation methods: Explicit formulae for:

Basic dynamic load rating and torque rating for angular types (AI, AII) and radial type (R).
Basic static load and torque ratings.
Rating life (L10) for applied radial load and for applied torque (life expressed via the relationship between C and equivalent load/torque).

Factors and parameters: Tables and expressions for geometry- and arrangement-dependent factors (f, f0, k, k0), contact angles, effective number of balls (Z), groove geometry (r/D), ball pitch diameter (D), and adjustment factors (for example b = 1.3 and λ = 0.9 appear in the calculation framework).

Contact stress guidance: Reference tables linking groove geometry to maximum contact stress (σmax) used to determine static ratings.

Illustrations: Diagrams of load/torque directions and contact angles for type AI, AII (angular) and type R (radial).

Practical applications and users

Design engineers and machine-tool component designers use ISO 23848-2 to size and specify ball splines for linear motion systems that must also transmit torque.

Manufacturers of ball splines and linear actuators apply the calculation methods and tables to certify product ratings.

System integrators, procurement and quality engineers use the standard to compare suppliers, verify rating life claims, and ensure compatibility with machine-tool requirements.

Test laboratories and reliability analysts use the L10 methodology to predict service life under specified loads and torques.
