Deep Groove Ball Bearings FAG 16004 -2Z

The 16004 -2Z deep-groove ball bearing provides a compact shaft mounting solution with dimensions of 20 × 42 × 8 mm and dust protection on both sides.

The FAG 16004 -2Z deep groove ball bearing is a single-row radial ball bearing, manufactured from standard rolling bearing steel 100Cr6. With a bore of 20 mm, an outside diameter of 42 mm and a narrow width of 8 mm, this rolling bearing fits into space-saving installations. It primarily accommodates radial forces as well as moderate axial loads in both directions. The design, featuring a sheet steel cage and standard radial clearance, ensures smooth running under normal operating conditions.

What is the 16004 -2Z deep groove ball bearing suitable for in mechanical engineering?

The 16004-2Z deep groove ball bearing is primarily used in designs with limited radial and axial installation space. Thanks to its narrow cross-section, the bearing is suitable for compact assemblies and drive elements with a narrow installation width. As the design is rated for operating temperatures ranging from –30 to +120 degrees, it covers a wide thermal operating range. The component is suitable for high speeds where the forces are predominantly radial.

What is the function of the 2Z cover plates in this rolling bearing?

The double-sided cover with non-contact cover discs made of sheet steel protects the bearing interior from coarse dirt particles and foreign bodies. Unlike abiding sealing lips, the Z-discs do not generate any additional friction, making the bearing suitable for higher speeds with low heat generation. When selecting the design, please note that gap seals are primarily effective against solid particles. Where necessary, an additional external housing seal is recommended to protect against pressurised liquids.
