HDW-0195: BELLEVILLE SPRING KIT (47 PC):

Fadal Drawbar Spring Stack (HDW-0195): American-Made for Superior Clamping Force

CNCPros is the preferred vendor for Fadal owners who demand uncompromising quality in their machine's critical sub-systems. We exclusively supply the HDW-0195, a genuine Fadal OEM hardware kit featuring a spring stack of 47 precision-engineered American-made Belleville springs. These components are the foundation of your drawbar assembly, designed to provide a superior, consistent clamping force for secure tool retention and optimal machining performance.

Advanced Engineering of American-Made Disc Springs

Our Belleville springs are not simply replacement parts; they are high-performance mechanical components manufactured to exacting standards. The "American-made" designation is a testament to their superior quality and metallurgical integrity.

• High-Precision Spring Stack: The kit consists of 47 conical disc springs, which are stacked in series to generate a powerful, consistent axial force with minimal deflection. The precise geometry and spring rate of each washer are critical for the overall function of the drawbar, ensuring a reliable and repeatable clamping force that prevents tool pull-out, even under heavy cutting loads.
• Superior Material Integrity: Manufactured in the USA, these springs are produced from high-grade alloy steel that is heat-treated for maximum fatigue resistance. This ensures the spring stack maintains its force over thousands of operational cycles, far exceeding the performance of lower-quality alternatives.
• Friction Management: The included high-performance grease is designed to minimize friction between the springs. This reduces wear and tear on the washers, extending the operational life of the entire drawbar spring stack.

How many springs should I put back into my drawbar?

Spring Calculations

Otherwise, a good rule of thumb is to have one spring peaking over the top of the spidle shaft and that is about as good as any farmer could get it.  Your drawforce for a non-locking drawbar (DRB-0030) is about 600 - 700 lbs.  For a locking drawbar (DRB-0003) you should see something around 1400 lbs or so.  Factory spec is 1800 lbs but I rarely see that in older spindles.
