Get one of those “link” belts. You won’t regret it.

As long as the belt isn’t too badly cracked or frayed, it should be fine. I don’t think that I’ve ever seen belt replacement as a periodic maintenance requirement for a belt driven tool.

Link belts are overrated and overpriced. A decent regular V-belt will be cheaper and perform just as well.

What link-belts always purport to overcome is “set”; i.e the tendency of belts to form to the pulleys and then vibrate. A good V-belt will not do this. Link-belts are way overpriced, have less contact with pulleys and, thus, less power transfer and have gotten way too much press lately!

So screw lew…

That being said: you replace a belt when it shows obvious signs of wear: frayed edges, way too much shine on the sides of the belt indicating slippage (might also be too little tension) or obvious signs of cracking or crazing on the belt surface.

I have belts that are at least 45 years old in my shop and working just fine.

The belts on my Jet 3 hp cab saw are the original, and over 20 years old, still look great, as it is hard to get any UV damage where they are and no “set” the saw still passes the nickel test.

I’ve still got the original belt on my old Crapsman saw, and it’s 26 years old…..Just keep an eye on it and if it shows wear, then replace it if necessary….8 months is nothing on a belt if both pulleys are in-line and the tension is set right… should be good to go for a long time yet…..only if you ran the saw in a production shop for 8 hours evey day, then you might need to start worrying…...

My Beaver Rockwell was purchased in 1976, wish the blades would last that long. The weight of the electric motor keeps the belt tight. Looks good with no wear or cracks. I run kevlar belts on the two little tractors I have, kevlar would outlast the saw for sure.

In respectful disagreement with EEngineer, link belts really do work fine, and even the best V belts WILL get a set to them. Having said that, if you use the saw frequently (more than once a week or so) I wouldn’t worry about set. I put link belts on my band saw because I use it maybe once a month, and it eliminated the vibration that the belts caused… I had replaced the OEM belts with Gates. A single quality V belt runs about $25.00, a quality link belt about $29.00, take your pick…

If your original belt doesn’t have a set to it, isn’t glazed, cracked, or frayed, then leave well enough alone and keep using it.

I have my 2nd v -belt on my first table saw, 34 years. I operated my own SEED cleaning plant for many years, slow Rpm, and little torque applications the link belts worked very well. I used them because in some of the machinery you had to take half the machine apart to put on a regular v-belt. Any machine that required HIGH torque or high RPM the link belts didn’t last as long, they were constantly stretching, a proper width V-belt worked better.

Unless you absolutely feel the need too replace. Only when it breaks. Save your money. The belts in these application will last a lifetime.

The only thing I might add to dbhost’s post is to point out that you can adjust the length of a link belt if you need to. I bought a used saw that sat for years, the belt looked great but its “set” caused a lot of vibration. I don’t think a link belt will pick up a “set”. -Jack

I have read somebody attesting that the rubber belts with the notches
on the inside are just as good as the link belts in terms of vibration.

Unless vibration is bugging you, replace the belt when it clearly needs it.
They last a long time in intermittent (home shop) use.

I learned from a power transmission guy that the belts you find in the hardware store are substandard to the ones you will find at a PT place. Self serving info it is, but I’ve found it to be true. The difference appears to be in the splice.

I like link belts because they remind me of craft time at summer camp. And they come in pretty colors. I just wish they showed a little more so people would be more impressed that I use them.

How do you know if the belt has enough tension? My TS motor hangs out the saw and tension can’t be adjusted. The tension is basically the weight of my 2hp motor.

What will the saw do if the belt is slipping during a cut?

The motor is what tensions the belt you can lossen the motor’s mounting bolts and adjust it a little . I have bogged my saw down twice today alone and it just kicks the braker on the back of the motor reset it and go back to work
