Product Overview

Joint Kits are an essential accessory for accurate off-line testing of powered assembly tools.

The performance of an assembly tool is highly dependent on the conditions of the actual production joint on which it is used.

Tooling engineers are well aware of the “mean shift” term used to describe the different torque delivered by the same tool when

applied to a soft or hard joint as defined by ISO 5393. It is therefore essential in testing and setting up tools off the production

line to allow for the joint condition which the tool will experience on the job.

Crane’s joint kits satisfy this requirement by using a bolt and suitably configured disc washers allowing free running of the bolt

and a subsequent torque gradient to closely match the production joint condition.

Two versions are available. Transducer Top Joint Kits are used in conjunction with female stationary transducers, while Table

Top Joint Kits are used with CheckStar rotary transducers. The latter are fixed to a workbench and are particularly suitable for

off-line testing of impulse tools. Both versions incorporate a selection of disc washers and spacers that may be configured to

simulate various joint conditions.
