Actuator Assemblies
Screw, gear and linkage actuators built and stroke-tested as delivered units.
Actuators assembled and stroked through their full travel before shipping, with the end positions set and recorded. The failure mode people miss is binding at one end of the stroke, not the middle.

What drives the price of this part
Derived from the callouts on this page. Where a driver is not on the drawing, it is not on this list.
- Material
- The first material listed, Aluminium 6082-T6, rates 9/10 on our machinability scale at 95 HB. On this shop's scale a harder alloy means slower passes and more tool changes, and that is cycle time the quote has to carry.
- Order size
- Minimum order is 10 pieces, so on a first order setup and programming are spread over very few parts and they are most of the price. Repeat orders at the same quantity are cheaper without anything on the drawing changing.
- Certification and paperwork
- ISO 9001:2015. On a certified family the inspection and documentation work is part of the price: first article inspection, material traceability and the dimensional report are produced per order, not per sample.
See how cycle time is calculated in the machining time calculator and what else moves a price in the cost driver reference.
How these parts are inspected
Matched to the callouts above and the instruments actually on the floor.
- Coordinate measuring machine (Zeiss CONTURA G2, two machines, GR&R 8.4% on the critical feature)
- Dimensional report against the drawing, with a 100% check on critical features rather than a sample
- Certificate of conformance and the mill certificate with every shipment
The full equipment list, with counts, is on the capability page; the inspection sequence is on quality and inspection.
Questions buyers ask
- Why test the full stroke rather than a sample position?
- Because backlash and binding show up at the ends, where the screw is fully extended and least supported. Testing mid-stroke tells you almost nothing.
