Alumina Ceramic Plunger and Guide Sleeve

This custom alumina ceramic plunger and guide sleeve set is intended for mechanisms that need electrical insulation, low contamination, hardness and resistance to repeated wear. The mating components can be manufactured to customer-defined geometry for dosing, guiding, positioning or reciprocating assemblies.

Where It Is Used

Potential applications include ceramic metering mechanisms, laboratory equipment, automation systems, fluid-handling assemblies and industrial machines. Alumina is often selected when a metal pair may corrode, introduce contamination or lose performance through abrasive wear.

Engineering Benefits

  • Hard, wear-resistant working surfaces
  • Electrical insulation and non-magnetic behavior
  • Good dimensional stability
  • Resistance to many chemical environments
  • Suitable for ground and polished cylindrical features

Manufacturing Options

Features such as bores, shoulders, grooves, locating diameters and end profiles can be produced according to a drawing. Grinding and finishing requirements should be selected according to the fit, motion and service environment. The mating relationship between the plunger and sleeve is especially important and should be clearly defined on the drawing.

Design Review and Inspection

Because technical ceramics are hard but more brittle than metals, impact loads, sharp corners and excessive assembly force should be avoided. Critical diameters, lengths and mating features can be inspected according to agreed drawing requirements.

Frequently Asked Questions

Can the plunger and sleeve be supplied as a matched set?

Matched-component requirements can be reviewed when the fit and inspection method are defined.

Can the ceramic surfaces be polished?

Grinding, lapping or polishing may be available depending on geometry and surface requirements.
