I’ve been working on redesigning a compact height-adjustable workstation for a physiotherapy clinic, and one of the main challenges I’m facing is finding a linear actuator that operates quietly. Patients are often sensitive to sudden noises during treatment, especially in therapy or recovery rooms. I’ve tried a few options in the past, but they either had a hum or noticeable clicking at the end of the stroke electric actuators https://www.progressiveautomations.ca/collections/linear-actuators . Does anyone have experience with super-silent actuators that are still strong enough for vertical lift? I'm trying to strike a balance between quiet performance and stable lifting.

I know exactly what you mean. We had to retrofit a bunch of ergonomic desks in a pediatric therapy space last year, and the noise factor was a huge concern—kids get anxious with even the faintest mechanical noise. We ended up using a couple of compact actuators from Progressive Automations, and the difference was noticeable. The PA-14 Quiet Linear Actuator in particular was a game changer—it runs quietly without compromising power. Even at full extension, there's just a soft mechanical movement, no buzzing or clunky stops. I’d recommend starting with one unit for prototyping. And if you’re dealing with a shared treatment space, the reduced noise actually makes conversations easier to maintain while the equipment is moving. Let me know if you want pics of our setup, I can send some.
