What Is A Trunnion On A Table Saw?

There are many types of table saws, each with a different type of trunnion. Even though there are many kinds of saws, the trunnion is an important part of each saw. It helps the blade turn. The trunnion is a key component of any table saw. A trunnion is the part of the saw that adjusts the height of the blade.

This blog post will show you what a trunnion is on a tablesaw.

What Is A Trunnion On A Table Saw

A trunnion attaches a machine or tool to another object. Attached to the table saw’s base, the trunnion can be found on the sides. It allows adjustments to the blade like tilt, raise, or low. The metal piece that connects the cabinet to the table saw is called a trunnion. A table saw trunnion usually has a ball bearing in it that the saw blade and fence ride on.

The trunnion is an accessory for table saws, that is used to attach the arbor to the underside of the table. This is the main adjustment point for the saw blade. It also adjusts the angle of the Blade. A table saw’s trunnion is an integral part.

Its the axle-like mechanism that allows the blade to move up and down. It may seem complicated but you can quickly figure it out by doing a few simple tests. Once you see how the trunnion works, youll realize that maintaining your table saw doesnt take as much effort as you thought it did.

Why You Need A Trunnion On A Table Saw

Problems You Face

You need a trunnion on a table saw if you have one or more of these annoying problems.

  • Your rip cuts may be burnt if the blade is set at 90 degrees.
  • Your wide crosscuts may be out of square.
  • You might feel your boards pull against the fence.
  • You might have related problems with the blade set at 45 degrees.

Trunnions are The Solution

A table saw is a power tool that can be used to cut wood. The blade can be tilted by the attached trunnions. Semicircular raised areas are found on the blades. These areas ride in grooves. These areas prevent the blade from tilting too far. To correct this problem, loosen the bolts holding the brackets, allowing them to move back and forth. This moves the brackets, correcting the problem.

The table saw blade may be perfectly aligned when it is flat, but not when it is tilted. The vibration and weight of the motor cause the rod-tie rods to shift, causing them to become misaligned. Lifting the saw while using it causes the same thing. The table saw’s underside is covered by trunnion brackets. You can loosen them to move the brackets that align the blade with the miter slot. This method is very easy to use, but it takes time to adjust the bracket position.

How Do You Align Trunnions To The Blade

There are two ways to align trunnions to a blade. One method is to use a trunnion pin. The second method is to use a set screw. I prefer the WEN blade.

Trunnion Pin

Trunnion clips are used to attach the blade to the trunnion. A trunnion pin is a small metal rod that goes through the center hole of the trunnion. This allows the trunnion to rotate freely. Make sure there is no friction or binding when using a TRUNNION pin. If the joint is clogged or has friction, the pin will not allow the trunnion’s movement to be smooth.

To prevent binding, lubricate the trunnion pin. Lubricating the trunnion pin helps to eliminate friction. Using a trunnion pin is the easiest way to align trunnions. For blades over 45 kg, it is not recommended to use the trunnion-pins. For heavier blades, use a set screw instead.

Set Screw

Set screws are used to connect the trunnion to a blade. A set screw is a threaded fastener that connects the trunnion to another part of the blade. After aligning the trunnion with its slot, use a set screw.

Before you use a set screw, ensure that the trunnion aligns with the blade. The blade could be damaged if the trunnion is positioned in an improper slot. After the trunnion is aligned to the slot it belongs to, attach the set screw to the trunnion. The set screw should be tightened to fit snugly against the trunnion. This will stop the trunnion moving laterally.

Remove any remaining slack from the trunnion after tightening the set screws. Tightening the set screw too much could cause the trunnion to bind.

FAQ,s

What is an Arbor on a Table Saw?

An arbor is a piece made of wood that holds the table saw blade in place during cutting. An arbor is basically a spindle connecting your blade to your tablesaw. An arbor is most commonly used to connect your blade to your table saw. This allows you to quickly change out blades, which saves time.

What the Role Of The Trunnion In The Saw

A trunnion connects the arbor to the blade of a saw. There are two types of trunnions used in the saw industry. The trunnion pin is one type, while the pinless trunnion is the other. Both allow the blade to move in relation to the arbor. There are some differences between the types.
Trunnion Pins are typically made of steel and attached to the arbor with screws. Pinless trunnions are usually made out of aluminum and are attached to the saw arbor using bolts.

How To Replace A Bearing In A Trunnion

Two types of bearings are used in a trunnion – roller bearings and ball bearings. Most applications use ball bearings. They are cheaper than roller bearings, but they do wear out over time. Roller bearings are usually used in higher-end machines where there is less friction.
If youre replacing a trunnion bearing, youll need to remove the shaft first. To remove the shaft, loosen the nut holding the shaft in place and slide the shaft off the trunnion. Next, remove the old bearing using a socket wrench. Replace the bearing with a new one and tighten it. Reassemble the trunnion and replace the shaft. Youre done!

How Do You Adjust A Table Saw Trunnion

Here is how do you adjust a table saw trunnion:

  • First, loosen the screws holding the trunnion to the baseplate.
  • Then slide the trunnion up and down until it fits snugly against the baseplate.
  • Next, tighten your screws.
  • Finally, test the trunnion to make sure it works properly.

How To Replace A Trunnion On A Table Saw

Here’s how to replace the trunnion in a table saw

  • Step 1: Locate the trunnion and the bolts that hold it in place. Trunnions are generally mounted on the motor end of the saw. It is a cylindrical piece with a shaft that extends vertically through the saw frame.
  • Step 2: Remove the bolts and pull the trunnion away from the machine using a pair of channel locks.
  • Step 3: Install the new tunnion, and tighten the bolts.
  • Step 4: Adjust the trunnion so that the bolts are fully engaged and that the alignment marks are aligned.
  • Step 5: Replace the saw blade and install the saw on the table so that it is ready for use.
