10個入り 6908-2RS フルセラミック ZrO2 ボールベアリング 40 × 62 × 12 mm 高精度・低摩擦の工業用ベアリング。機械・設備向け。電気モーター、ロボット、コンベアに最適。高負荷容量と低摩擦を実現。Sealed 2RS 過酷な環境用
✔️ 40mm ID x 62mm OD x 12mm width, 10-piece full ceramic set
These are full ceramic bearings made with zirconia (ZrO2) race and balls, designed for long-lasting performance in tough environments. The PTFE cage reduces friction and supports reliable operation in dry or low-lubrication setups. This 10-pack is ideal for batch replacements in robotics, lab equipment, and industrial machinery where clean, metal-free bearings help prevent contamination and corrosion. The 40x62x12 mm size fits common housings and is a popular choice for high-speed, high-temperature applications.
✅ Inner diameter (ID): 40 mm
✅ Outer diameter (OD): 62 mm
✅ Width: 12 mm
✅ Bearing material: full ceramic (ZrO2) with PTFE cage
✅ Seals: 2RS rubber seals on both sides
💡 What is a full ceramic bearing good for and when should I buy ceramic instead of steel? In short, they shine where corrosion resistance, high speed, and clean operation matter.
- High rigidity and corrosion resistance in harsh environments
- Low friction and non-magnetic operation for precision tasks
- Long service life at high speeds and temperatures
- Lightweight, chemical-resistant choice for robotics and automation
