Full Ceramic Deep Groove Ball Bearing – Non?magnetic, elektrisch isolierend, corrosion resistant, operable up to 1200°C. Self?lubricating, runs dry without oil or grease. Ideal for semiconductor, aerospace, medizinisch, chemical processing, vacuum systems, and high?temperature furnace applications where steel bearings inevitably fail.
We offer Si3N4 full ceramic deep groove ball bearings in a wide range of standard sizes, including miniature series (down to 2mm ID), metric and inch dimensions, and large?diameter configurations. Custom retainer materials (SPÄHEN, PTFE, PA66, full complement without cage) are available.
Der 6205 hybrid ceramic deep groove ball bearing is lighter than steel balls, elektrisch isolierend, and has a lifespan that is 3 Zu 5 times longer. It can withstand high temperatures and reduce friction.

Wartung: Erfordert weniger häufiges Reinigen und Schmieren als Standardlager. Das mitgelieferte Hochgeschwindigkeitsschmiermittel ist für die Keramik-Stahl-Schnittstelle optimiert.
We supply standard grades from G5 to G100, with higher grades (z.B., G5, G10) offering the tightest tolerances for critical, high-speed applications. Sizes are available in a wide range, from miniature sizes of 0.5mm (0.0197") to larger diameters of 50.8mm (2.0") and beyond, depending on the material.
Materialien & Key Properties:
• Chrome Steel : The industry standard, offering an excellent balance of hardness (60-67 HRC) and load capacity. Ideal for most general industrial and automotive applications.
• Stainless Steel (440C, 316): Provides superior corrosion resistance. Grade 440C is martensitic and can be hardened to 58-60 HRC, suitable for food, marine, and chemical environments. Grade 316 (austenitic) offers maximum corrosion resistance for highly aggressive media.
• Ceramic (ZrO2/Si3N4): These advanced bearing balls are lightweight (60% lighter than steel), elektrisch isolierend, and highly resistant to wear, Korrosion, and thermal expansion. They operate effectively in high-speed, high-temperature, and chemically hostile environments where metal fails.
