Description

Product Details

The tJRS (threaded joint rate simulator) is the only fully automated joint test bench that utilises a threaded fastener system. This means that joint conditions can be set up in the same way as in real fastener applications and the joint can be automatically ‘backed off’ after each test.

As a result, assembly tools can be tested, offline, under the most realistic conditions of any automated joint simulator bench, in a quick and efficient manner.

Traditionally, automated joint test benches have used friction brake systems in place of a threaded fastener. The reasons for this were to overcome the two main issues which are having to reverse, or back-off, after each rundown and the cumbersome nature of re-configuring the joint characteristic.

Whilst friction brakes can easily be reset, removing the back-off issue, they introduce many of their own problems often resulting in the simulator having significantly different properties to actual joints the tools will be used on. Crane’s tJRS joint test bench sets the standard for accurate and precision torque management.
