.197” ID .357” OD
Use these bearings with a 3/16” pivot.
Note that the ID is slightly larger than a 3/16” pivot. This won’t be a problem as the pocket is what holds the bearing in place, not the pivot.
Caged bearings with hardened ball bearings.
Sold by pairs. Ordering 1 quantity will get you a pair of bearings, one for each side of your blade.
These bearings are caged in brass.
To use these:
Mill a pocket into your frames to depth. Some makers will mill a pocket in both the blade and the frame. These bearings are .066” thick so you will want to mill your pockets to .051” depth leaving .015” clearance. You can experiment with slightly deeper pocket(s) but watch for blades binding against the frame or pocket dirt binding things up with a closer clearance. Washers are generally not used with a bearing system.
These bearings can be pocketed using a letter “T” counterbore which can be difficult to find. We are working on sourcing and selling appropriate sized carbide tipped counter bores for these bearings. The pocket can be oversized with no issues.
We will also be sourcing and selling hardened races for these bearings. A race is a thin washer with a small roller channel stamped into the metal. We tested 60HRC hardness in our samples. To use a race, you would mill your pocket slightly deeper to match the depth of the race and bearing set up. The advantage to the race is: they are harder than Ti and the channel break in is done for you already. Also, this allows a bearing to be used with a g10 frame. The down side is you have to mill a slightly deeper pocket and you have an additional part.
