624, 624Z, 624ZZ, 624RS, 624-2RS Ball Bearings 4x13x5mm – Full Series Deep Groove Bearings for Industrial & Mechanical Applications

• 624: Open type – ideal for applications requiring re-lubrication or custom sealing
• 624Z / 624ZZ (624-2Z): Single or double metal shields – provide effective protection against dust and help retain lubricant
• 624RS / 624-2RS: 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, conveyors, power tools, agricultural machinery, and automotive components.

Most sealed versions are pre-lubricated with high-performance grease for maintenance-free operation. The 624 series supports both radial and limited axial loads, making it a versatile choice for OEMs, replacements, and repair applications.
