Great tool. I clamp it down in the vice and use it to press in the new bearing cups into the drive shaft. Makes easy work out of it. Beat the heck out of using sockets and the vice.

Highly recommended this product especially if you have bone Swiss ceramic bearings. Keeping them clean and lubed will increase The longevity of your bearings!

Installation was fairly simple.  The directions were clear.  It took me about an hour.  There are a lot of YouTube videos that walk you through the installation.

I'm not sure what tool the previous reviewer is noting about removing the bottom fastener.  All you need is a flat head screwdriver to remove it.

I really didn't need this but decided to change this part out.  Takes about 5 minutes and as long as you are changing out the bearing, I decided to do it.

Installe in my MTD-Bolens mowing tractor Mowing deck easely. I did not remove the spimgles as this might cause the self tapping bolds that hold the aspindle to the deck frame to shear off as I have read in many posted comments. so that means you end up buying complewte new spindle assemblies for about $80-$150. The bearings cost a small fraction of that. Difficulty is 3-4 wrenches out of 5. removing and replacing the deck on the tractor is not easy either.

As far as the bearings are concerned: they appear to be of good quality and should last several years.

The first thing i did with this puller kit is run a bottom tap on the extensions and bearing separators, and a a die on all the threaded shafts. The next thing i did was replace the bearing separated nuts with some from ace hardware that are steel and Rockwell rated. I then coated everything with silicone lubricate. I have now pulled bearings off dc mothers, axle shafts, CV joints. I have used it about twenty times in a short period of time without any problems or failures. I think i save a lot of money overall by doing these few things.

This tool was easy to use and did exactly as it was intended.  I recommend it if you have to install any race, bearing or seal.  Also the price was
very reasonable and since I may never need to use it again, it was cheaper than having the work performed by a shop.

installation was pretty straight forward, washers provided were wrong size so had to go buy proper washers, install took about about 30 minutes once I had proper size washers. Only launched one time so far and trailer guides worked well, really simplified the process. I can't say yet how long they will last, we will see.

I used these to replace the steering bearing in a 1994 Kawasaki Ninja 500. Removal of the old bearing races involved using a drift and hammer to slowly tap them out. Installation was easy using a piece of 1" Class 200 PVC (not schedule 40). 1" class 200 PVC is just the right size to slide over the steer tube on the triple tree, but the sidewalls just small enough that it contacts only the bearing and not the bearing cage. Block on bottom, block on top of pipe, few whacks with a heavy hammer and the bearing was seated nicely.

The steering action is once again smooth and these should last the rest of the life of the bike. They're well constructed and arrived very quickly and with thorough instructions. I will buy another pair when my second bike needs its steering bearing replaced.

I used my new Aircat 1150 to replace the pressed bearings on my Toyota Camry. It was a joy to watch the bearing slide out as the impact hammered away on it. Going back in with the new bearing was even easier.

Installation for this product is a breeze. Took me about 20 secs. That is less than a minute. Just use a flat screw driver and gentle lift off old one. Snap on new one in the aligning holes. Thats it you are done! Some people may want to add glue which is just a matter of preference.
Delivery was very fast even though i chose standard 5 days shipping item arrived in 2 days.
Very please

The instructions are not that great but you can find a few videos on youtube explaining how to install it. The toughest part for me was separating the tub from the old shaft. I guess water was leaking in and rust welded the shaft on there. My advice is to clamp a pair of vice grips on the shaft and make sure its on there real tight. Hit the vice grips with a hammer to break the shaft loose. Hit the shaft with a hammer a few times then back to hitting the vice grips. It took me a solid 30 minutes but eventually the shaft popped out of the tub. Other than that, it was pretty easy to install. You can rent the bearing press tool on ebay for $25 and $70 shipping. When you return the tool you'll get the $70 back.

The bearings appeared to be the same as the original ones. Fit well, good value. No problems with installation. You may want to buy new mounts as the supplier advised.

Nice bearing definitely smoother than old ones. I like that you can easily remove shields for cleaning. Price is high but if they last a few years I be pleased. 4 stars because price.

Works fantastic and easy to install. Read the manufacturer's website and this will help with what tools are needed. Their site is quite helpful.
