6310, 6310Z, 6310ZZ, 6310RS, 6310-2RS Ball Bearings 50x110x27mm – Deep Groove Ball Bearings for Industrial & Mechanical Equipment

Complete 6310 series deep groove ball bearings in standard size 50mm (ID) × 110mm (OD) × 27mm (W), available in multiple configurations for reliable performance in heavy-duty industrial, automotive, and mechanical applications:

• 6310: Open type – ideal for applications requiring re-lubrication or custom sealing
• 6310Z / 6310ZZ (6310-2Z): Single or double metal shields – provide effective protection against dust and help retain lubricant
• 6310RS / 6310-2RS: 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 speeds. Widely used in electric motors, pumps, fans, gearboxes, compressors, conveyors, agricultural machinery, construction equipment, and industrial power transmission systems.

Most sealed versions are pre-lubricated with high-performance grease for maintenance-free operation. The 6310 series supports both radial and limited axial loads, making it a versatile solution for OEMs, replacements, and repair needs.
