It could be “non of the above”, would depend on the arbor.

Here I thought that collection of tools first shown are “gear pullers”. The bearing puller in the red box is what I have, and it has the clamshells needed for bearings. The HF set is not the best, but for the 2-3 times a year I use it it has worked fine. Like you said it’s cheap. I keep thinking about getting a USA set, but to be honest, I just don’t use it enough.

The first pic is advertised as “Use these heavy duty pullers for removing gears, sprockets, bearings, pulleys and much more”. I will probably use these at most once a year. I’m just looking for pros/cons of one type of puller vs another.

If you intend to re-use the bearing, you cannot grab it by the outer race, that would screw up the bearing, and that’s also the way the gear pullers would have to do it. Now, if you intend to replace the bearings and don’t care how they come off, the gear pullers may remove them….or they could possibly tear the outer race off, leaving you with the inner race still to remove (and bearings rolling all over the floor). With the “real” bearing puller, the clamshells tighten up around the bearing journal and pull it off using the inner race. There has to be room to get the clamshells in there obviously. I use them when I press the bearings back on as well. So, the red box is what you want, but that still may not work on the saw’s arbor…depending on the access you have. BTW, what I refer to as clamshells is the “separator” part of the kit. You don’t necessarily have to buy anything, you can get those gear pullers from most auto places, and they probably have the bearing puller kits as well.

I’ve got the lower red-box HF puller set, and it’s paid for itself in removing bearings and pulleys. The bolts and threads are standard sizes, so you can make additional jigs for the pullers.

Another thought is that many auto parts stores loan (with deposit) or cheaply rent stuff like this.

both of these will pull on the outer race unless the bearing has an extended inner race. the plate style will most likely get you on to the bearing though. often on the ends of the finger style there is something in the way or too close to get the end past to get on to the bearing.if you are going through the trouble of removing the bearings get new ones. to reinstall use a tube slightly larger than the shaft .005 or so and press on the inner race of the bearing going onto the shaft. care must be taken if the housing is tight in order not to pre load standard ball bearings also.
