Our product range comtains a wide range of Sapphire Windows, PRECISION JEWEL PIVOTS, SAPPHIRE RODS, RING JEWEL BEARINGS and SAPPHIRE JEWEL BEARING ASSEMBLIES

Sapphire Windows

Sapphire’s attributes include high mechanical strength, temperature stability, wear resistance and chemical inertness. As a result, a Sapphire Window will exceed other optical materials in harsh environments, providing a barrier between elements. Sapphire Windows are used commonly in optical and mechanical applications. Our offering includes a wide range of Sapphire Window stock parts as well as sapphire window customization opportunities.

RING JEWEL BEARINGS

  • Model R08.00

Serving as radial/sleeve jewel bearings, Ring Jewels are used with straight cylindrical shafts. Ring jewels offer flexibility due to their many combinations with endstones. Straight holes restrict lateral movement, but require accurate alignment when the clearance between pivot and jewel bearing is tight. Olive holes offer lower friction with pivots and permit assembly adjustment. provide minimum contact with pivots for light, intermittent end thrust. Where thrust load is continuous, an endstone is usually combined with the ring jewel.

SAPPHIRE JEWEL BEARING ASSEMBLIES

  • Model RS-20-CO
  • inside Diameter .0123/.0125

Ring Jewels can be mounted into bushings or screws. This style can ease your mounting of the bearing into your final instrument. A ring jewel can be mounted into a plain bushing or into a screw to be coupled with an endstone. To assist with fine tuning assembly for load applications Ring Jewel Assemblies can also be mounted with or without a spring. Applications include Flow Meters, Gauges, Meters, Indicators, Aircraft Instruments, Gyros and Watches

SAPPHIRE BEARING ENDSTONES

  • Model ES-40
  • Diameter 2-56, 1/4
  • size 187x.035"

Endstones find wide use as a thrust bearing in combination with a ring jewel which serves as the annular bearing. The endstone may be mounted in the same housing with the ring jewel or mounted separately in an adjusting screw—especially when the end of the pivot extends beyond the radical bearing. Pivot ends in both cases should be highly polished. Typical Applications: Flow Meters, Gauges, Indicators, InsulatorsSpacers, Potentiometers, Gyros, Aircraft Instruments, Watches and Clocks

VEE JEWEL BEARING

  • Model VS-20
  • Lenght .125"
  • Size V1.25

ee Jewel Assemblies are typically mounted in screws. This style can ease your mounting of the bearing into your final instrument. Vee Jewel Assemblies can be mounted with or without a spring for load applications which also can help with fine tuning assembly into the instrument. Please contact us for pricing, customization and delivery. Typical Applications: Ohmmeters, Voltmeters, Gauges, and other Indicating Meters, Compass, Timers and Relays

SAPPHIRE BLADES

  • Model SP-99 sapphire blade
  • Length .725/.735"
  • height 028/.032"

Sapphire Blades are an excellent choice for various applications. Sapphire's hardness and excellent surface finish provide a superior surface for precision work. Sapphire blades are commonly used on fiber optics for cutting and scribing. Sapphire is also a non-thrombogenic material for use in surgical applications. Typical Sapphire Blade Applications: Fiber Optic Scribes, Tape Cleaners, Surgical Knives

SAPPHIRE NOZZLES

  • Model SP-160
  • Length .302/.322"

Sapphire Nozzles are used where a longer Inner Diameter to Length ratio is desired. Using sapphire nozzles will provide longer life than using metal and we can hold tighter tolerances due to sapphires acceptance of higher surface finish. Typical Sapphire Nozzle Applications: Gas & Air Flow, Wafer Jet Cutting & Cleaning, Ink Jet Printing.

SADDLE PINS

  • Model SP-95
  • Length .177/.185"

A Sapphire Saddle Pin is a rod with a concave groove in the middle. This area provides a wear surface which can capture the element and keep it centralized. Saddle pins are valuable as wiring guides

PRECISION JEWEL PIVOTS

  • Model N-1D
  • Length 485/.495"

The shape and type of precision pivots used is determined by the operating conditions, the type of jewel bearing, and other design factors involved in suspending the moving element in the system. Cylindrical precision pivots can be supported by any of the ring jewel designs and combinations. End thrust may be taken by having a shoulder on the pivot ride on the polished face of the ring jewel bearing or by using an endstone bearing to take the thrust from precision pivots with rounded ends

SAPPHIRE RODS

  • Model SP-1
  • Length .095/.105"

Sapphire Rods are used in a wide range of applications. A sapphire rod can be made with all surfaces polished for optical and wear applications or with all surfaces fine grind (un-polished) to serve as an insulator. Sapphire Rods are available in a range of outer diameter and lengths. OD's as small as .0175"
