Sapphire / Ruby Bearings, Through-hole, End-face, Groove

synthetic azure / ruby is second only to diamond in hardness and has been widely used in much industrial area ascribable to its high stamina and potency. After good shining, it has a very perfect clash resistance. This feature enable it to be used as a give birth or wear-resistant material in a variety of instrumentation, preciseness machinery and other fields .
As a jewel bear, it normally has the follow three types : through-hole bearings, end-face bearings and rut bearings .

Sapphire / ruby through-hole bearings consist of a series of products, chiefly used in a variety of accurate chronograph, automatic memory devices, preciseness instruments and early devices of the rotating system of the patronize bearings .
godhead Optics can provides the following main types of sapphire / ruby through-hole bearings : Plane straight/olive hole bearings, single-cup plane straight/olive holed bearings, double-cups plane straight/olive holed bearings, raised olive hole bearings, and single-cup raised olive hole bearings, etc .
common Specifications of Sapphire / Ruby Through-hole Bearings :

outside Diameter ( D ) diameter from 0.5mm to 200mm
Tolerance of “D” 0.004 – 0.05mm

Sapphire / ruby End-face bearings are normally used in conjunction with sapphire / ruby through-hole bearings and are chiefly used to support and withstand the effects of thrust. They have high severity, good abrasion underground, corrosion resistance, high gear temperature resistance and other characteristics, and after good polish, the working coat roughness can reach 0.01 microns .
godhead Optics can produce the following chief types of end-face sapphire / ruby bearings : Plane end-face bearings, spherical end-face bearings .
common Specifications of Sapphire / Ruby End-face Bearings :

Diameter (D) from 0.8mm to 5mm
Tolerance of “D” 0.004 to 0.05mm
Height (H) 0.4 to 2.0mm
Tolerance of “H” +/-0.01mm
“R” of edges 0.05 to 0.12mm
Surface Roughness Working surface: Rz0.01-Rz0.2, Assembly and sink surface: Rz3. 2
Materials Synthetic CZ/KY sapphire, ruby

arrow Sapphire / Ruby Groove Bearings, Cup Bearings

Sapphire / ruby Groove bearings ( Cup Bearings ) are chiefly used in electronic instruments, hot water measuring instruments, liquid quantify instruments and single-phase / three-phase KHW meters of the motion system beam support parts .
creator Optics can produce the following main types of sapphire / red groove bearings ( Cup Bearings ) : spherical bearing, conic bearings, double cups on one confront bearing, and single cup on double surfaces bearing. These shapes are shown in the figure above.

common Specifications of Sapphire / Ruby Groove Bearings :

Outside Diameter (D) from 0.8mm to 25mm
Tolerance of “D” h7 to h9
Height (H) 0.3 to 25.0mm
Tolerance of “H” 0.01 to 0.10mm
Curvature radius “SR” 0.10 to 150mm
Tolerance of “SR” +/-0.01 to +/-2mm
Groove / Cup depth “h” 0.05 to 12mm
Tolerance of “h” +/-0.01 to +/-0.1mm
Tapered Groove Angle “a” 40 to 160D
Tolerance of “a” +/-5D
Surface Roughness Working surface: Rz0.05-Rz0.8, Assembly and sink surface: Rz3. 2
Materials Synthetic CZ/KY sapphire, ruby
