Ballshop 10Pcs Internal Bearing Extractor Kit 9-23mm Motorcycle Bearing Puller with 5 Sizes Open Clips Carbon Steel Bearing Puller Removal Tool Set for Motorcycle Flywheels Generator

Did the job, good price and easy to use.

Good range of sizes, well packaged, seem durable, little tricky to use but work great once you get the tool set properly. Only issues were some swarf inside some of the tools, and they were very oily, but easily wiped off. So far have been great value.

Bought this for only £15 to remove needle bearings from my Motorcycle linkage, but tool only destroyed old bearing and tubes crumpled trying to remove shell.Firstly there are no instructions with this tool, but there are independent youtube videos showing how to use it. This is a good thing as I had no reply when I tried to contact the seller.Now the ID of my bearing was 17mm. This tool jumps from 14mm to 19mm so it was able to grip the end of the bearing but not fit closely along the sides. Thus it just stripped out the rollers but left the case. This meant that the 19mm tool fit through the bearing shell and gripped without crushing against the outer edge, but first the spacer tubes crumpled somewhat, then when I reinforced the tubes with jubilee clips on the outside the edges of the tool folded over and the middle crushed and bowed outwards as others' photos showed. The tool totally failed to extract my bearings despite heating the outer part and I ended up having to use old fashioned techniques with a cut down washer, a shaft and a big hammer.The tool does appear well made and fairly solid, and is probably great for light weight bearing removal but alas the large tubes are too thin and weak for tougher bearings and the metal of the puller tools appears a little soft.

Easy to use - too a few minutes to engage with and pull out the remains of a disintegrated bearing body from my bike pedal, allowing new bearings to be inserted. Might never use this again but much cheaper than a new pedal.

Disappointed. Suited to lightweight (eg. bicycle) applications only. The tool arrived roughly machined and failed on 1st use. "Japan Quality", "CR-V" (picture 1). Collets packed with swarf and with rough edges throughout (picture 2). After careful cleaning and preparation of the collets, suitable spacers, supports and tools were prepared (picture 3). Using only a light screwdriver for a tommy bar and an 8" spanner, the appropriate sized collet (for a dia. 20mm ID bearing) was carefully positioned and tightened into position so that the collet shaft was fully expanded into the id and hence the tapered foot engaged. Heat was applied using a hot air gun to expand the aluminium wheel housing. Appropriate spacers were assembled. Applying careful and steady application of the load on the withdrawal nut (again only using moderate pressure on the 8" spanner and light tommy bar) after 3 full turns of the nut, the assembly was dismantled and checked to see if the collet was still engaged and if the bearing had moved. The bearing had not moved. The procedure was repeated after the collet had been loosened, re-seated and tightened with slightly more pressure. Repeating with a few extra turns, dismantling, checking etc., ... then repeating ... Eventually the collet completely failed in the foot (picture 4) and pulled through with light load on the extraction nut. Resulting inspection also showed failure in the expander (picture 5). At no time was excessive pressure applied to the hand tools used. Accepted that the bearing was tight (hence the need to purchase a tool rather than drift it out) but tool failure occurred at reasonably light loads and was due to Poor machining design (the expander is just a circular shaft with a rapid taper at the tip) and questionable CR-V material (light filing cleaned up the badly burred edges and attached swarf). I don't know if the tool was supposed to be heat treated and had been missed, but the heat applied with the hot air gun could not have heated the tool above any "tool-steel" heat treatment limit. Lightweight tool, possibly suited to bicycles in its current form or really easy bearings.Tool will be returned - I look forward to the refund and response.

Amazing extractor that came to the rescue while trying to do a bearing service on my Whyte S-150s (10 bearings in total). I originally bought a similarly priced bearing extractor online that broke after the first two bearings were extracted. Unlike this amazing piece of kit, the other extractor was made of cheap metal and used blunt force to push the bearings out. On the 3rd and 4th bearing attempt, I managed to destroy both bearings and the tool. Panic then set in when I realised I had to remove the broken outer bearing rings from the frame (see attached pic). As luck would have it, I stumbled upon this amazing set that quickly extracted both outer rings of the damaged bearings and the remaining 6 bearings with almost no effort at all. I highly recommend this tool to all mountain bikers who service their bikes at home. Great quality at a giveaway price

This was used to extract a blind bearing from a small item of garden machinery. Worked well and easily pulled out the outer race. 4 stars because I’ve only used it once, not sure how well it would manage bigger/tighter bearings.

internal puller snapped on the tenth sleeve we pulled, cheap metal, but cheap price, so in this case you get what you pay for. lasted longer than a more expensive version we bought
