SKF 6306-2ZJEM Double Shielded Deep Groove Ball Bearing

SKF 6306-2ZJEM is a compact, single‑row deep‑groove ball bearing built for reliable radial support in rotating equipment. It features a straight cylindrical bore with a 30 mm bore, 72 mm outer diameter, and 19 mm width, and it ships with double shields on both faces (2Z) to protect the raceways from dust and moisture. The bearing belongs to SKF's 6306 family and offers a C3 internal clearance, which accommodates thermal expansion and installations with slightly larger fits. With its deep‑groove geometry, it supports radial loads with modest axial loading tolerance while maintaining a simple, maintenance‑friendly design. This combination of size, shielded protection, and clearance class makes it a versatile choice for general purpose applications where a compact bearing is required to fit limited spaces in machinery and drive assemblies.
