My Ninja blender motor was fine but the bearings in the blade were burnt up and causing the blender to “freeze”. It is like new again ! Review: A lot of bad reviews about leaks but it works great, must be the luck of the draw - I read some of the poor reviews this had but I bought it anyways because of the price difference compared to the manufacturer. The 7 Fin blade on desertcart is about $15.00 with free shipping, The manufacturer wants almost $40.00 with shipping. I’ve had this Ninja for at least two years but it wasn’t until recently I started using it twice a day when I discovered what a Smoothie is. Where have smoothies been all my life. . Straw berries, bananas, frozen yogurt and orange juice all blended together. So easy. As you can tell in the video, about wore my blender and the blade out. It makes so much more noise now, I have to keep it in the laundry room away from the other rooms in the house. I might have to move it in my garage. This blade came with a gasket so I tried to use it but the blade will not fit over my cup, so I didn’t use it. I was expecting it to leak, but it didn’t. It works great. I guess I’ll see as time goes by. So far, I can’t complain, it does what it’s suppose to with no leaks. I couldn’t be happier. As for cleaning, I just run hot water over the blade after each use. The other blade I washed and black grease started leaking out from under the fins, now it’s noisy and kinda loose. ## Features - Compatibility: The 7 fins blade size is 3.9 in/10 cm (Diameter) fit for Ninja Auto-iQ NN100, NN100A, NN101, NN102, BL455-30, BL481-30, BL482-30, BL485, BL486CO, BL487, BL487A, BL487T, BL491, BL492, BL492IS-30, BL494, BL640-30, BL641-30, BL642-30, BL680A-30, BL681A, BL681C, BL682-30, BL682QT-30, BL685-30, BL687CO-30, CT680SS, CT680CO2SS, CT641-30.

I use it on a auto-iq nutri ninja. If you go to ninja website, I think it lists the replacement parts. It looks the same but I can't be sure. It goes by the number of spokes that fit down into blender. **Q: Does this replace blade come with the black plastic lid that screws on or is it just the blade? every picture shows the blade connected to the lid** A: You mean the black plastic that has 7 fins as shows in the picture, right? yes, it come with the 7 fins black plastic that can be screwed on the blender cup. **Q: Is there a way i can get the rubber ring alone?** A: yes. I would do a search for Silicone Rubber Gaskets Seal Ring for Nutri Ninja Auto iQ. Make sure that you get the silicone one. ie: https://www.amazon.com/SunnyMemory-Silicone-Replacement-Extractor-BL456-30/dp/B09LS3CVDW **Q: Do you carry this same ype of blade for your BL494 Model?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ This works, fits, great ! *by D***4 on October 20, 2025* One of the best items from Amazon I have purchased in a while.

Feels like cheap Chinese copy. The blades are not sharp, the axle sits loose in the shaft, and it already feels unstable. It’s only a matter of time before food or liquid leaks through the bottom and mixes with the motor area. Would not recommend.” ## Frequently Bought Together - for Ninja Blender Blade Replacement Parts 7 Fins Compatible with Nutri Ninja Auto iQ BL642-30 BL482-30 BL682-30 with Silicone Rubber Gaskets Seal Ring Mixer Attachment, Updated - Replacement 24oz Blender Cup with Sip & Seal Lid For Nutri Ninja BL450 BL456 BL480 BL482 BL640 BL642 BL682 BN401 BN751 BN801 Foodi SS101 SS151 SS351 SS401 Ninja Blender Auto IQ Blade, 2-Pack … - (Pack of 2) Blender Replacement Parts 7 Fins Extractor Blade Assembly with Rubber Gasket Compatible with Nurti Ninja Blenders Auto iQ BL480 BL401 BL642 BL801 NN102 --- ## 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.us/products/187633597-7-fins-blade-fit-for-ninja-auto-iq-blender-bl642](https://www.desertcart.us/products/187633597-7-fins-blade-fit-for-ninja-auto-iq-blender-bl642) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-02*
