Full Ceramic 6311 Ball Bearing With ZrO2 Ceramic Balls PTFE Cage And Ceramic Inner And Outer Rings C3 Fit 55mm Bore 120mm Outer Diameter 29mm Width For High Durability Low Friction And Long Lifespan

Ceramic 6311 ball bearing with ZrO2/PTFE, 55x120x29 mm
✔️ 55mm bore, 120mm OD, 29mm width; ZrO₂ balls, PTFE cage; Quantity 1

This is a full ceramic 6311 ball bearing built with zirconia balls and a PTFE cage. It’s designed for dry lubrication, high temperature tolerance, and long life in precision equipment, robotics, and other demanding machinery.

✅ Ball material: Zirconia ceramic (ZrO2) for high wear resistance
✅ Cage material: PTFE for low friction and chemical resistance
✅ Races: Zirconia ceramic with C3 clearance for smooth rotation
✅ Lubrication: Dry design for clean environments and low maintenance

💡 What is a ceramic ball bearing used for in high-precision machinery? This handy overview explains typical roles and benefits.

- Used in spindles, precision axes, and robotic drives - Ideal for high-speed, dry-running applications with minimal maintenance - Ceramic balls and races offer corrosion resistance and low friction - Great for clean environments where contamination must be minimized
