clutch test equipment

performance testing of clutch covers

TQC have produced a variety of bespoke test machines for automotive clutch covers for both OEM and aftermarket suppliers.

The machines are manually loaded and unloaded with the option of manual or automatic clamping. The performance test is fully automatic with the operator protected by fixed guarding or a safety light guard.

The machines are designed to perform a variety of tests to verify the performance characteristics of the clutch covers.

The machine can accommodate a size range of clutch cover assemblies from 150mm to 350mm diameter
