Nautilus treadmills are designed with the highest quality materials and state-of-the-art technology to ensure optimal performance, safety and ease of use. With features such as heart rate sensors, low step-up heights and Nautilus' signature SuperSoft walking belts, Nautilus treadmills are a top choice for both beginners and hardcore fitness enthusiasts.

Absorption Control Technology

The cushioning system of the Nautilus T916 treadmill features absorption control technology, allowing for optimal comfort with every step. Whether you're walking, jogging or running, the T916's cushioned belt automatically adjusts to any pace to keep your ankles, hips and knees protected.

Wide Belts and Low Step-Up Heights

The Nautilus T912 commercial treadmill is an ideal piece of equipment for fitness clubs and gyms, and it's designed with a 22-inch belt that is suitable for individuals of varying weights and sizes. Additionally, Nautilus treadmill belts are one of the easiest treadmill parts to replace in the event of a tear or excessive wear. The T912 also crafted with a low, 7.5-inch step-up height to accommodate users of smaller stature.

Repair Assistance is Available

While all Nautilus treadmills are manufactured with high-quality, durable materials and designed to withstand weights of up to 400 pounds, continual use and accidental damage can cause parts to break or wear down. If your Nautilus treadmill breaks down and you need a new part or repair assistance, Sears PartsDirect can help.
