Deep Groove Ball Bearings FAG 6008 -Z

The 6008-Z deep-groove ball bearing from FAG Wälzlager, measuring 40x68x15 mm, offers reliable radial load-carrying capacity with one-sided protection against dirt particles.

The single-row deep-groove ball bearing 6008 -Z is one of the most versatile rolling bearings in industrial engineering. With a bore of 40 mm, an outside diameter of 68 mm and a width of 15 mm, this rolling bearing primarily accommodates radial loads as well as low axial forces in both directions. Manufactured from standard roller bearing steel (100Cr6) with a robust sheet steel cage and standard radial clearance, this FAG roller bearing model is characterised by smooth running and universal applicability.

What is the 6008-Z deep groove ball bearing suitable for in industrial applications?

This single-row deep-groove ball bearing is particularly useful where rotating shafts need to be supported. Typical applications include mounting positions with predominantly radial loads and moderate speeds. Thanks to the single-sided sheet metal cover, the bearing is particularly suitable for enclosed spaces, such as inside a housing. Lubricant can circulate freely on the open side, whilst the protected side shields the interior of the bearing from coarse external contaminants.

What is the function of the single-sided cover plate in the 6008-Z deep groove ball bearing?

The ‘-Z’ designation indicates a non-contacting cover plate made of profiled sheet steel on one side of the bearing. As the cover plate does not contact the inner ring, the friction torque remains low, enabling high speeds without additional frictional heat. Before installation, it is advisable to check the mounting direction: the open side is typically mounted facing the lubricant reservoir, whilst the closed ‘Z’ side acts as a mechanical barrier against the ingress of dirt from adjacent areas.
