Sliding bearings for magnetic mixers

Ceramic sliding bearings from Kyocera are the reliable solution for magnetic mixers, which are used in sterile production processes in the pharmaceutical, biotech and food industries. These components are used where accurate pairing of male and female bearing is required together with exceptional sliding properties, chemical resistance and chemical inertia which ensures the safety and sterility of the mixing process.

Thanks to high-quality zirconia and silicon carbide ceramics, the sliding bearings offer excellent thermal shock resistance, enable CIP/SIP cleaning without disassembly and reliably prevent contamination from abrasion or residues.

Advantages of ceramic sliding bearings from Kyocera

• Abrasion-resistant & contamination-free - No particle emissions, even under high loads and high rpm
• Biocompatible & FDA-compliant - Ideal for sensitive pharmaceutical and biotech processes (also available: USP Class VI and cytotoxicity tests)
• Perfect surface quality - Ra < 0.5 μm prevents bacterial colonisation and product adhesion
• CIP/SIP-capable - can be sterilised without disassembly due to good thermal shock resistance
• Minimal friction & shear forces - for low-friction and efficient processes
• Long service life - High impact strength (zirconia) and wear resistance (silicon carbide) ensure survival dry run conditions
• Easy to service - simple disassembly and replacement of bearing parts on site

Areas of application

Ceramic sliding bearings are preferably used in mixers with magnetic coupling - especially where maintenance-intensive sealing systems such as mechanical seals are to be avoided. Typical areas of application are

• Production of active pharmaceutical ingredients
• Biotechnological fermentation processes
• Aseptic mixing processes in the food and cosmetics industry
• Systems with high chemical and temperature resistance requirements

Customised solutions & manufacturing expertise

Kyocera offers sliding bearings for different designs and installation situations - also with:

• integrated threads in ceramics (grinded ceramic threads or glued in metal threads)
• Metal-ceramic connections through shrink fit or glueing
• Complex geometries through F-molding (near-net-shape casting)
• Bearing components are manufactured using high-precision grinding technology - for maximum accuracy of fit in the micrometres range.
