Product Description

Synthetic sapphires are next to diamonds in hardness which makes these highly polished bearings scratch and shock resistant. They also have a long wear life, and are highly resistant to heat, corrosion and distortion. In addition, sapphire bearings are nonmagnetic, dielectrically strong and provide good shaft end support and freedom of motion. They are especially well suited for use in delicate instruments such as ammeters, voltmeters, compasses and precision indicator devices. The jewel radius should be 2.5 to 3 times the pivot radius. In general, the greater the ratio between jewel and pivot, the greater the sensitivity and pivot roll. The contact area of the pivot should be highly polished and a finish of 2 to 3 micro-inch on the pivot radius is recommended. Small Parts also offers Brass Vee Jewel Assemblies in 80/85 Degrees (VJA-1, VJA-3, and VJA-5) and 85/95 Degrees (VJA-7)and Stainless Steel Vee Jewel Pivots in 50 Degrees (p/n VJPX-1D), 70 Degrees (p/n VJPX-2D) and 53 Degrees (p/n VJPX-7D)

Appears to be a quality item at a fair price. It's what I was expecting from the description, and I'm sure it will work to my expectations.

It works perfectly for the needle bearing for the EZ-Spin motor from Lasersaber. I may even find other uses for it.
