Deep Groove Ball Bearings FAG 608 -Z

The 608-Z deep-groove ball bearing from FAG Wälzlager, with an 8 mm bore and a single-sided Z-end cap, offers a compact solution for rotating shafts.

This single-row deep groove ball bearing 608 -Z primarily transmits radial forces and, due to its design, also accommodates axial loads in both directions. Manufactured from standard rolling-bearing steel 100Cr6, this version features a robust sheet-steel cage to guide the rolling elements. With compact main dimensions of 8 mm inner diameter, 22 mm outer diameter and 7 mm width, this miniature bearing is suitable for use in numerous precision mechanical drives and compact machine components.

In which applications is the 608-Z deep groove ball bearing used?

The 608-Z deep groove ball bearing is primarily used in compact small drives, precision mechanical devices and guides. Thanks to the single-sided sheet metal cover, the rear of the bearing remains accessible for lubricant supply from the housing. At the same time, the end cover shields the rolling elements from particles in the surrounding environment. The permissible temperature range is from –30 to +120 degrees Celsius.

What are the distinctive features of the Z cover plate on the 608-Z deep groove ball bearing?

The metallic Z-cover plate seals the bearing without contact. Unlike sliding seals, this gap protection does not generate any additional frictional torque, which means the bearing runs smoothly and is designed for higher speeds. With standard radial bearing clearance and tolerance class P0/PN (corresponding to ABEC 1), the component is suitable for common fits in general mechanical engineering. The cylindrical outer ring without a flange allows for flush mounting in smooth housing bores.
