Looks and fits like the original blade, screaming loud...
If this is OEM then perhaps the company standards have gone down. This blade looks like OEM but is stiff and VERY loud!. I purchased a new blade thinking the bearings were going on my original blade which is why it is deafening when making a smoothie. The (Ninja) machine works much quieter when other attachments are used, but it is unbearable when using this blade for smoothies. I purchased a cheap chinese blade replacement last time and it works the same as this blade (loud and stiff). Perhaps I need to get a Vitamix like I originally wanted...

Poor quality, but does the job. 1/3 the cost of OEM (Original Equipment Manufacturer)
This is a poor quality replacement for your Ninja smoothie blender. It is very stiff, very loud, and has the smell of burning rubber after use. It's been in use for 1 week now making 1-3 smoothies per day and I do not expect it to last. It does seal well and the blades are a replica of the OEM blades that came with the blender. These blades do not feel like they have true bearings in them, but I cannot confirm without taking it apart. I have the 1500 Watt Ninja Kitchen System with Auto-IQ Boost (BL687CO). The rest of the system is good, but the blades for the Smoothie cups wear out too quickly. I went thru 2 OEM blades in 14 months (I blend 0-3 smoothies per day). The OEM blades appear to have true bearings in them (though I have not taken them apart to confirm). OEM blades move freely and easily when new, but when these bearings go bad it is unbearably loud and the blades become quite stiff. OEM blades cost 3 times as much as these do.
