BlogSKF Deep Groove Ball Bearing 6202 – 2Z / ZZ
Metric deep groove ball bearings – Shielded
SKF shielded deep groove ball bearings are versatile ball bearings suitable for high and very high speeds. They can support both radial and axial loads in both directions. The ball bearings require very little maintenance. SKF deep groove ball bearings come in a range of different sizes. This range consists of single row ball bearings.
Shielded (2Z) bearings are equipped with two metallic dust shields to prevent the ingress of dirt and foreign matter. 2RZ bearings are 2Z bearings equipped with two low-friction seals.
