Designed for rugged duty, it features an internal bronze screw nut, double-ended ball bearing motors, and hardened gears. With IP65 ingress protection and thermal overload safeguards, this 12V actuator excels in demanding industrial and material handling applications. ## Description This Warner K2G20-12v-BR-18 B-Track linear actuator has an 18" stroke and a 20:1 gear ratio for use in rugged duty applications such as platform and engine lifts. This K2 series unit is capable of moving loads up to 1200 pounds at a rate of 0.5 inch per second. The linear actuator uses a solid bronze screw nut for transferring the load, and has double-ended ball bearing motors and hardened gears for rugged duty use. Its protective coatings and O-ring seals provide an Ingress Protection (IP) 65 rating for protection against dust and liquids, and the unit is permanently lubricated. The 12VDC motor has thermal overload protection and has an operating voltage range of 10 to 16VDC. This linear motion actuator is suitable for use in applications such as deck and implement lifts for tractors, wheelchair lifts, and flow control mechanisms.SpecificationsPower requirements12VDC 25 ampDuty cycle10 percent maximum on time for 80 to 100 percent load capabilityControl switchdouble pole, double throwOperating range–30 to +140 degrees F (-34 to + 60 degrees C)Degree of protectionIP65Linear motion actuators are independent units that, when combined with a switch and power source, push or pull loads in a straight line. Actuator types (mechanical, hydraulic, pneumatic, piezoelectric, electro-mechanical, and telescoping) vary and their application is determined by the power source available, as well as the load and space requirements. Linear motion actuators are used in a variety of applications, such as computer disk drives, deck and implement lifts for tractors, wheelchair lifts on a vehicle, and flow control mechanisms, such as flood gates on a dam.Warner Linear manufactures electromechanical actuators and controls. The company, founded in 1927, is headquartered in Belvidere, IL. Review: NOT marine grade - Bought two of these to replace engine lifts on my trimaran sailboat. Worked great but after only 4 years they are completely corroded. Both the rod casing and the motor casing. They are super expensive. NOT marine grade. I won't be buying again. Much cheaper options that I'm sure will last just as long if not longer. Review: searay330 2009 - i found these reviews and bought two to replace the flimsy original units. they had rusted and would trip the breaker almost every time. Since the breaker is in the bilge, i thought it was just a matter of time before i was completely screwed. I agree with the other reviews, much beefier and solid than the original, bolts right into bottom bracket and is the same size, extended length. I also replaced the connectors with heat shrink type. one part that gave me a lot of grief is the top connection. there are two unequal length tubes that connect the actuator to the underside of the engine hatch. because these replacements are so much stronger, these original extensions would not fit over the top cylinder. I would up purchasing stainless steel tube 1-1/4" diameter. Hard to fabricate but absolutely worth it. also, make sure you make the new extensions the exact same length. otherwise the hatch will not close completely. I also chickened out and had two 2x4 posts made to hold the hatch in place while i replaced the actuators. That thing is scary heavy. good luck to the next guy, you can do it. ## Features - Pushes or pulls load in 18" stroke - 20:1 gear ratio for moving loads up to 1200 lb. at 0.5" per second - Internal bronze screw nut for load transfer - Double-ended ball bearing motors and hardened gears for rugged duty use - 12V operation with an operating range of 10 to 16VDC ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.6 out of 5 stars 17 Reviews | ## Images ![K2G20-12v-BR-18 B-Track K2 18" Stroke Length Rugged Duty Actuator - Image 1](https://m.media-amazon.com/images/I/71GJtC+vd0L.jpg) ## Customer Reviews ### ⭐⭐ NOT marine grade *by S***D on November 23, 2025* Bought two of these to replace engine lifts on my trimaran sailboat.

I didn't need to modify anything, as the stroke and length were the same as the original unit that came in the boat. This unit bolted in exactly as the original unit that was on the boat did. This unit came with a plastic connector which felt flimsy, so I cut it off and used my own marine grade but connectors to wire it to the boat. --- ## 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.co.za/products/15100604-k2g20-12v-br-18-b-track-k2-18-stroke-length](https://www.desertcart.co.za/products/15100604-k2g20-12v-br-18-b-track-k2-18-stroke-length) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-10*
