6711, 6711Z, 6711ZZ, 6711RS, 6711-2RS Ball Bearings 55x68x7mm – Miniature Deep Groove Ball Bearings for High-Speed & Precision Mechanical Systems

High-precision 6711 series miniature deep groove ball bearings in size 55mm (ID) × 68mm (OD) × 7mm (W), engineered for compact yet robust mechanical applications requiring smooth rotation and reliability. Available in multiple configurations to suit diverse operating conditions:

• 6711: Open type – ideal for re-lubrication or custom sealing in controlled environments
• 6711Z / 6711ZZ (6711-2Z): Single or double metal shields – protect against dust and help retain lubricant
• 6711RS / 6711-2RS: Single or double rubber seals – offer superior resistance to moisture, dirt, and contaminants

Manufactured from high-quality chrome steel (GCr15), these bearings feature precision-ground raceways for quiet, low-friction operation and extended service life under light to moderate radial loads. Commonly used in small electric motors, power tools, drones, RC models, robotics, medical devices, 3D printers, office automation equipment, and precision instrumentation.

Most sealed versions are pre-lubricated with high-performance grease for maintenance-free operation. The 6711 series supports both radial and limited axial loads, making it suitable for space-constrained, high-speed systems where efficiency and durability matter.
