Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 23848-2 was prepared by Technical Committee ISO/TC 39, Machine tools.
ISO 23848 consists of the following parts, under the general title Machine tools — Ball splines:
⎯ Part 1: General characteristics and requirements
⎯ Part 2: Dynamic and static load ratings and rating life

Introduction
The ball spline is a power transmission component based on recirculating balls, which is designed to translate
axially while transmitting torque by an anti-friction means. The ball spline is selected for its smooth operation,
high-speed capability, low friction and high radial and high torsional load capacity. This part of ISO 23848
specifies and standardizes the basic dynamic load rating and torque rating, the basic static load rating and
torque rating and the 90 % rating life for ball splines of type AI, type AII and type R.
