Anatomy of a Blender, Part 6

anatomy of a blender, part 6

Let's dive once again into the inner workings of Blendtec blenders. This time, we're going to look at In which we examine a true masterpiece of engineering.

Feature #10: Steel-on-Steel Power

In a Blendtec blender, the power is transferred directly from the motor to the blade. All the intervening parts are steel and machined for a precision fit. This steel-on-steel approach results in lower vibration, reduced noise, and increased reliability.

Blendtec motor drivetrain

Blendtec's steel-on-steel power train is more reliable, lasts longer, and can transfer greater loads to the blade. In nearly all other blenders, the power goes from the motor through a breakable plastic coupling. The coupling is designed to break if the motor overloads, in order to protect the motor. Unfortunately, this design also limits blending power and decreases the life of the coupling.

Typical blender power train

A typical blender motor includes a plastic breakable coupling, which limits power transfer from the motor and reduces jar life.[/caption] A Blendtec blender, on the other hand, automatically detects an overload condition and shuts down, eliminating the need for a breakable plastic coupling. Have you ever noticed whether your blender has a breakable plastic coupling? If so, now you know why! Share your thoughts in the comments section below.

    We are always working on improving our products and our jars have recently been improved with double bearings so they’re stronger than ever! Your jars are a wear item so over time, it will need to be replaced. However, they are covered under warranty so as long as you stay compliant (don’t take it out of the country it was purchased in, don’t use it for commercial use, etc.), you’ll be able to get it replaced should something go wrong. Hope this helps! Feel free to call our customer service team at 1-800-748-5400 with any further questions.

    I have been researching what new blender to get our family as we have destroyed the last few ones. I am very interested in Blendtec, however I am quite put off after researching the amount of gasket/bearing fails in your blade jars.

    I am wondering when Blendtec will be revamping/improving the blender housing of the blade to prevent this from occurring? As well I would need to purchase a “twist jar” to accommodate making nuts, and with only a 3 year warranty on a $150 jar that can leave a consumer a little worried and hesitant to purchase your product.

    Thank you in advance for your reply.

    I have a Bendtec Blender and the jar started smoking. When I examined it I noticed black gasket shavings all over the place. Further inspection showed that drivetrain gasket is failing. Is there a way to replace or repair it?
