Design and Construction

The SKF 6205-2Z features a single row of precision steel balls housed within deep raceway grooves. This configuration allows it to support radial and axial loads in both directions, making it highly versatile. The bearing is equipped with metal shields (2Z) on both sides, which protect the internal components from contaminants while retaining the lubricant inside.

Key Dimensions:

• Bore Diameter: 25 mm
• Outer Diameter: 52 mm
• Width: 15 mm
• Weight: Approximately 140 grams (0.309 lbs)

The bearing is manufactured from high-grade bearing steel, ensuring excellent resistance to wear, fatigue, and corrosion. The cage is made from sheet steel, providing strength and stability to maintain ball spacing and reduce friction.
