In high-end manufacturing, aerospace, semiconductors, medical treatment, deep-sea exploration, chemical engineering and other fields, ordinary bearings can no longer meet the requirements of extreme working conditions. Special material bearings are precision transmission components designed for harsh environments such as high temperature, low temperature, strong corrosion, high vacuum, non-magnetism, insulation and ultra-cleanliness.

Different from conventional bearing steel (GCr15), special material bearings adopt special materials such as ceramics, high-performance stainless steel, engineering plastics, titanium alloy, non-magnetic alloy and high-temperature alloy. Combining material science and precision manufacturing, they achieve performance limits that ordinary bearings cannot reach.

Main Classification of Special Material Bearings

1. Full ceramic / hybrid ceramic bearings (silicon nitride Si₃N₄, zirconia ZrO₂)
2. High-performance stainless steel bearings (316L, 2205 duplex steel, Hastelloy)
3. Engineering plastic bearings (PEEK, PPS, POM, PI)
4. Non-magnetic alloy bearings (non-magnetic stainless steel, copper alloy)
5. High-temperature alloy bearings (M50, Inconel, W-series high-temperature steel)

6. Titanium alloy bearings (TC4, TA2, lightweight and corrosion-resistant)

Why Use Special Material Bearings?

• Withstand an ultra-wide temperature range from -250℃ to 1000℃
• Resist corrosion from strong acids, alkalis, seawater, salt spray and chemical solvents
• Non-magnetic, insulating, anti-static, and do not interfere with precision signals
• Ultra-clean and dust-free, suitable for vacuum and semiconductor applications
• Self-lubricating, maintenance-free, ultra-high speed and ultra-long service life

• Lightweight, high rigidity, impact-resistant and highly stable

•
