The IP65 rating is fairly solid for my application since it will be mounted under the vehicle. The actuator came with instructions and mounting hardware. I bench-tested it using a 12V power supply, and it operated correctly in both directions. The internal limit switches also functioned as expected. I partially disassembled the lead screw housing to inspect the internal limit switch setup. It uses normally closed (NC) microswitches soldered in place with resistors. The switches are mounted in a plastic track that slides into the aluminum housing. During disassembly, I noticed the internally threaded push rod contained aluminum shavings from the threading process. While this doesn’t appear to affect operation, it suggests some inconsistencies in manufacturing quality control. The plastic guide at the end of the housing (where the push rod rides) is secured with a single screw. The screw boss showed a crack, likely from over-tightening during assembly at the factory. I also found no sealant applied at this interface, which could allow water ingress where the guide seats into the aluminum body; I plan to add sealant here. Inside the guide, there is an O-ring intended to provide sealing. However, the fit was fairly loose and did not inspire much confidence in its effectiveness. I replaced it with a slightly thicker O-ring to achieve a tighter seal without adding noticeable friction. Overall, the actuator functions well. It pulls strongly even under load on a car battery and does not sound like it struggles. It produces some noise during operation, but nothing excessive. I did not use the supplied mounting hardware, but it appears reasonably robust. There are a few quality control concerns, but at roughly $50, it is still a solid value for the performance. One limitation for my use case is that the non-driven clevis cannot be rotated 90 degrees, which would have made mounting easier with the included brackets. It appears to be cast in place, likely for strength. (UPDATED EDIT) I contacted the seller regarding the quality issues and they responded, but I never received notification from Amazon for this response. So, I changed my review from 3 to 4 stars. They were very grateful for the feedback and stated they would forward that information to their engineering department. They also offered me a partial refund for the part which I accepted. ## Frequently Bought Together - JQDML 4 Inch 4" Stroke 660lbs/3000N Speed 5mm/s Heavy Duty IP65 Waterproof Linear Actuator 12V Electric Actuator with Mounting Brackets - OONO Forward and Reverse Relay Module for Motor/Linear Actuator, Reversing Relay Module (DC 12V) - IndusTec Wired 20A 12V - DC Motor Polarity Reversing Rocker 3 Position DPDT Momentary Automatic Reset Switch (On)-Off-(On) 6 Pin DPDT Double Pole Double Throw --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/529927136-jqdml-12v-heavy-duty-linear-actuator-4-inch-stroke-660](https://www.desertcart.sk/products/529927136-jqdml-12v-heavy-duty-linear-actuator-4-inch-stroke-660) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-09-01*
