The 6205 ZZ C3 E NSK is a single-row deep groove ball bearing with a steel cage. It has a diameter of 25mm (1 inch) inside and 52mm (2 inches) outside, with a width of 15mm (0.6inches). It is made of bearing steel and manufactured by NSK. The bearing has two metal shields (ZZ) on both sides to prevent dirt, dust or other contaminants from entering the bearing. The "C3" designation identifies it as having a radial internal clearance greater than the normal clearance. The "E" stands for enhanced dust proofing. The bearing is suitable for medium radial loads, and moderate thrust and axial loads. It can run at high speeds, including high-speed internal combustion engines.
