Bearing & Squaring in Atlanta Georgia

The Second Bearing system is using a "true bearing" using real sealed bearings.  This is done by high end vertical panel saws typically costing over $25,000 but there is one company making panel saws for a tenth of that figure using actual bearings.  This company, (Saw Trax Mfg. Inc.) makes their panel saws in Kennesaw GA.  They use 3 sealed bearings per carriage corner for a total of 12 sealed bearings per carriage.  This arrangement has two bearings on top to carry the weight and one bearing on the bottom to "Load" the top bearings.  The bottom bearing ensures constant pressure during a cross cut.   By using a true sealed bearing system like this, you get both accuracy and ease of movement during a cut.

A similar indexing system is used for the vertical guide tube posts is patented.  The manufacturer calls it the "Accu-Square".  Nine holes spaced 8/32 apart are centered in the frame.  Another nine holes spaced 9/32 apart are centered in the bottom guide tube bracket.  Only one hole in the frame and guide tube bracket will line up at any given time and adjustments left or right can be made in 1/32 increments.  Once adjusted, the bracket is locked to the frame using a sheet metal screw keeping the guide tubes from ever shifting in relationship to the frame.  This system is patented and is guaranteed to never go out of square.

There are two types of bearings used in most panel saws.  The first is a low cost U-bolt with nylon rings around the U.  The rings are squeezed between the guide tubes and the U bolt at the same time.  As these rings try to roll, the carriage moves on the guide tubes. A bottom button glide is used to "Load" (put pressure) on the U-bolt rings.  As you might already see the flaw in this system is friction.  The tighter you get the tolerances to take out the play, the harder it will be to move the carriage causing a trade off of ease of movement and accuracy of the cut.
