Deep Groove Ball Bearings FAG 6306 -2Z

The 6306-2Z deep-groove ball bearing from FAG Wälzlager, measuring 30 x 72 x 19 mm and featuring cover plates on both sides, offers protection against dirt particles whilst maintaining low friction.

The 6306-2Z deep groove ball bearing from FAG Wälzlager is a single-row radial ball bearing with a bore diameter of 30 mm, an outer diameter of 72 mm and a width of 19 mm. Manufactured from standard 100Cr6 bearing steel, the component primarily accommodates radial loads and, due to its design, can also handle axial loads in both directions. The outer ring has no flange or groove. An integrated sheet steel cage guides the rolling elements precisely at operating temperatures ranging from –30 to +120 degrees Celsius.

In which applications is the 6306-2Z deep groove ball bearing used?

This rolling bearing is designed for applications in general mechanical engineering, as well as for rotating drive units and electric motors. It provides guidance at medium to high speeds and is frequently used in gearbox shafts or electric drives. The sheet metal shields on both sides keep coarse foreign matter and dirt particles out of the bearing interior, enabling the component to maintain its running characteristics under moderate contamination.

What features do the cover plates offer in the 6306-2Z?

The version with the suffix -2Z features non-contacting metal cover plates on both sides. As the sheet metal plates do not come into contact with the rotating inner ring, no additional frictional heat is generated compared to sliding seals. This allows operation at high speeds. The standard radial bearing clearance and tolerance class P0 ensure stable, low-vibration operation within standard fit tolerances and the specified temperature range.
