ALT Extractor
The ALT Extractor is a bearing removal specialist.
When trying to remove a bearing in a configuration where a bearing spacer is keeping you from using a bearing press, the ALT Extractor will securely grab the bearing in a way that doesn’t damage the bearing spacer that sits behind it.
The ALT Extractor is currently in production.
Pre-Orders now open.
Shipping expected end of August.
The Tool
Basically the ALT Extractor is designed to grab onto a bearing. Once attached, you can use the ALT Extractor’s threaded stud, along with some leveraging pieces, to pull the bearing out of it’s bore. Just like the controlled motion of a bearing press.
How it works
The ALT Extractor design is based around a split collet with a very small lip on it. The tool goes in through the front of the bearing and the Split Collet expands into the bearing inner diameter AND the very small gap between the bearing and bearing spacer.
Once engaged, the ALT Extractor can pull the bearing out using the leverage pieces of my bearing presses.
Better yet …watch the video below.
Why it works great
The tool expands until it hits the inside of the bearing inner ring ensuring a tight grasp AND a perfect placement of the small lip that hooks the back side of the bearing. The fact that the tool automatically stops in this position ensures that the lip never over expands which is something that could damage the bearing spacer that sits behind the bearing.
The design is further stabilized by the way the wedge piece fits into and expands the split collet. The Wedge has 4 symmetrical angled faces that are always in full contact with the split collet. That means that as you expand the split collet and apply force to remove the bearing, nothing shifts.
Configurations
The ALT Extractor removes the first bearing in a BSB configuration.
A BSB configuration can be found in these types of bike parts.
Sizes:
Extractors come in these sizes which correspond to the bearing inner diameter (ID):
10, 12, 15, 17, 18, 20 & 25mm
Fits bearing widths*:
5-14mm for new system
5-12mm for old system
* IMPORTANT
Kits sold BEFORE June 2024 can only remove bearings up to 12mm wide.
If you have a kit sold BEFORE June 2024, choose ALT Extractors with “OG” in the product name. PS. There are no 10 & 12 sizes of the “OG” version. They are NOT necessary.
If you have a kit, or are buying a new kit (with Sleeves), choose ALT Extractors WITHOUT “OG” in the product name.
The reason for this is the length of the Sleeves in those kits. Kits sold before June 2024 have shorter sleeves.
Features:
Designed to have a strong grasp on the bearing being removed.
Designed to not damage the bearing spacer behind the bearing being removed.
Secure grasp of bearing because collet expands inside bearing to contact the bearing ID.
Solid, full contact expansion of split collet thanks to the wedge design.
Does not require the bearing spacer to move off to the side.
Works with a controllable screwing motion. No hammering or yanking.
Split collet (part that grabs the bearing) is made of durable stainless steel.
Sold in Individual Sizes and Packs:
The ALT Extractor is sold as individual ALT Extractors and in different packs.
Size the ALT Extractor to the bearing inner diameter.
IMPORTANT: The ALT Extractors need to be used with the leveraging pieces in my system, so this will help you choose:
If you already have another manufacturer’s bearing press and only want to use the ALT Extractor to remove bearings. You will need the ALT Extractor(s) of your choice and one of the Sleeve Packs with Step. Either acetal or aluminum.
If you have one of my kits (with leveraging pieces) sold after June 1, 2024, or if you are planning on getting one of my new kits, get the regular versions of the ALT Extractor. (ie. NOT “OG”).
If you have one of my kits (with leveraging pieces) sold before June 2024, you MUST use the “OG” versions of the ALT Extractors. Sizes 10 & 12 are not effected but sizes 15-25 can only extract bearings up to 12mm wide.
If you only want one size of ALT Extractor for one job, consider waiting until I start selling individual pieces. That way, along with the ALT Extractor, you could only get the Step plus the one Sleeve size you need rather than getting the whole Sleeve pack with Step. This option is a couple months away.
