Regarding the relevant parameters and applications of 6208 series bearings:
1. 6208: This is a standard single cover Deep Groove Ball Bearing, with an inner diameter of 40mm, an outer diameter of 80mm, a thickness of 18mm, a rated dynamic load of 29.6kN, a rated static load of 18.3kN, and a rated speed of 9000r/min. It is usually suitable for components such as rotating shafts or bearing supports in mechanical equipment.
2. 6208-Z: This is a single cover type bearing with only one iron reinforced cover to protect the inside of the bearing from dust and pollutants. Its inner diameter, outer diameter, and thickness are the same as standard 6208 bearings. Usually used in environments that require light loads and are not easily contaminated.
3. 6208-2Z: This is a double cover type bearing that uses a steel cover to cover the bearing ring and ball to prevent dust and pollutants from entering the interior of the bearing. Its inner diameter, outer diameter, and thickness are the same as the standard 6208 bearing. It is typically used in application environments where it is necessary to prevent dust, particulate matter, or pollutants from entering.
It is worth noting that the difference between 6208 and 6208-Z/2Z lies in the sealing performance of the bearings. 6208 has no cover and there is no sealing gasket inside the bearing; The 6208-Z/2Z adopts a cover made of iron or steel to protect the inside of the bearing from dust and pollutants. Suitable models need to be selected based on specific usage needs.
