Product Specification

6004 Full ZrO2 Ceramic Deep groove Ball Bearing 6004CE Motorcycle Wheel Bearings

The 6004CE is a fully ceramic deep groove ball bearing specifically designed for extreme environment applications (highly corrosive, high-temperature, strong magnetic fields, or metal-free requirements). It is widely used in chemical process pumps, semiconductor wafer equipment, high-temperature kiln drive systems, and medical MRI equipment. Model breakdown: “6” denotes deep groove ball bearing type (supports radial loads and slight bidirectional axial loads); ‘00’ indicates ultra-light radial series (optimized for compact installation in small precision equipment); “4” is the inner diameter code (calculated as 4×5=20mm, conforming to standard 6000 series dimensions); “CE” denotes a fully ceramic construction (inner ring, outer ring, and rolling elements made entirely of ceramic—no metal components, completely eliminating corrosion and magnetic interference risks). Unlike hybrid ceramic bearings (metal rings + ceramic balls), its all-ceramic structure maintains exceptional resistance in harsh environments, making it particularly suitable for applications with high risks of metal contamination or corrosion failure.

• Interchangeability: Dimensions (20×42×12mm) fully match standard metal/hybrid 6004 bearings, enabling direct replacement in harsh environments. Critical notes: 1. Full ceramic bearings have lower load capacity than metal variants—avoid loads exceeding 6.5 kN. 2. Ceramic is brittle; avoid 剧烈冲击 (impact load ≤ 1.5× static load) during installation.
• Main Applications:
  • Chemical industry: Corrosive liquid pumps, acid-base conveyor shafts (resists chemical erosion)
  • Semiconductor manufacturing: Wafer handling robots, plasma etcher components (no metal contamination)
  • High-temperature equipment: Small high-temperature kiln fans, solar thermal power generation auxiliary parts (withstands 300°C+ temps)
  • Medical devices: MRI machine guide rails, surgical tool motors (non-magnetic, no interference with imaging)
  • Food/pharmaceutical: Sanitary pumps, filling machine shafts (avoids metal rust and contamination)
