I bought my bandsaw in 1980, and the tension on it is or has been released probably a dozen time, that is to install a new blade.

At times it sit for weeks without use, and there was or is ever any problem with that saw, works now as well as when new and after I added a riser block to it, sawed metal with it, for that I added a small motor and jack shaft.

If you believe the steel or bearings or the springs will deform, better have a look at your car, suspension rubber and springs sit for years and years, used or not and the bearings have the weight on it al the time as well.

Here is my 4 speed saw, where I added the riser block and the low speed setup to, also an easy add-on to make me able to roll the saw around, just the tension bold is getting rusty by never being used
