Product Description

Set in Brass, Vee Jewel Assemblies are screw mounted. Spring loaded assemblies are recommend in an environment of shock and vibration. The Beryllium copper spring acts as a shock absorber and permits the jewel and pivot to move without breaking and then return to its normal position. Non-spring loaded screw mounted assemblies are typically used in a more stable environment. Pivot not included. 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 individual Vee Jewels in 75/85 Degrees (VJ-0469), 85/5 Degrees (VJ-0787 and VJ-0800) and 90/95 Degrees (VJ-1244)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)
