Ceramic Ball Bearing 6701-2RS Si3N4 Ceramic Balls ABEC-5 Quality Double Sealed With Rubber Seals Deep Groove Radial Bearing For Precision Machinery Featuring Chrome Steel Cage And High-Load Applications

Ceramic 6701-2RS Sealed Bearing with Si3N4 Balls - ABEC-5
✔️ Double sealed 12x18x4 mm ceramic ball bearing, ABEC-5 Single

The 6701-2RS is a double-sealed, radial deep-groove ball bearing built with chromium steel races and a ceramic Si3N4 ball set for reduced friction and higher speed. The rubber seals keep out dust and contaminants, and the unit ships as a single bearing (12 x 18 x 4 mm) ready for direct mounting in precision motors, 3D printers, gear boxes, and linear actuators.

✅ 12 x 18 x 4 mm dimensions (ID 12 mm, OD 18 mm, width 4 mm)
✅ Ceramic balls Si3N4 reduce wear and friction
✅ Double rubber seals RS for dust protection
✅ ABEC-5 quality (EMQ) for high-speed operation
✅ Chrome steel race and cage included

💡 What is a sealed ceramic ball bearing used for in precision equipment?

It's handy for high-speed, low-friction rotations in compact machinery.

• High-speed, low-friction rotation in motors and tooling
• Dust-resistant seals extend bearing life
• Ceramic Si3N4 balls reduce wear and corrosion
• Ideal for 3D printers, CNC machines, and robotics
