6211, 6211Z, 6211ZZ, 6211RS, 6211-2RS Ball Bearings 55x100x21mm – Deep Groove Bearings for Industrial & Mechanical Equipment

Complete 6211 series deep groove ball bearings in standard size 55mm (ID) × 100mm (OD) × 21mm (W), available in multiple configurations for reliable performance in industrial, automotive, and mechanical systems:

• 6211: Open type – ideal for applications requiring re-lubrication or custom sealing
• 6211Z / 6211ZZ (6211-2Z): Single or double metal shields – provide effective protection against dust and help retain lubricant
• 6211RS / 6211-2RS: Single or double rubber seals – offer superior resistance to water, moisture, and contaminants

Made from high-quality chrome steel (GCr15), all models feature precision-ground raceways for smooth, low-noise operation and long service life under radial loads and moderate to high speeds. Widely used in electric motors, pumps, fans, gearboxes, compressors, conveyors, agricultural machinery, and industrial machinery.

Most sealed versions are pre-lubricated with high-performance grease for maintenance-free operation. The 6211 series supports both radial and limited axial loads, making it a versatile solution for OEMs, replacements, and repair applications.
