Deep Groove Ball Bearings FAG 608 -2Z

The 608-2Z deep-groove ball bearing from FAG Wälzlager is a compact miniature roller bearing with an 8 mm bore, a 22 mm outer diameter and cover plates on both sides.

The 608-2Z deep groove ball bearing is a single-row radial ball bearing, manufactured to tolerance class P0/PN (ABEC 1). This component from FAG Wälzlager primarily absorbs radial forces, supports shafts with low friction and, thanks to its compact dimensions of 8 × 22 × 7 mm, is suitable for space-saving designs. Both the rings and the rolling elements are made from 100Cr6 bearing steel for high dimensional stability under load.

What is the 608-2Z deep groove ball bearing suitable for?

Typical applications for this miniature bearing are found where rotating shafts are mounted in confined spaces. Such roller bearings are primarily used in compact drives and precision mechanical assemblies. In addition to high speeds, the design accommodates moderate radial forces as well as axial forces in both directions. The integrated sheet steel cage guides the rolling elements evenly in the raceway and ensures low-vibration operation at varying speeds.

What is the function of the end caps on the -2Z version?

The designation -2Z indicates non-contact gap seals made of sheet steel fitted on both sides. These cover plates protect the interior of the bearing from coarse dirt particles and foreign bodies without generating additional friction or heat. This makes the variant particularly suitable for applications involving higher speeds within a temperature range of -30 to +120 degrees. Lubricants remain protected within the bearing chamber, whilst the normal radial bearing clearance ensures a balanced operating clearance for standard fits.
