Deep Groove Ball Bearings FAG 625 -2Z

The FAG 625-2Z deep-groove ball bearing is a compact miniature bearing with a 5 mm bore, an outer diameter of 16 mm and end caps on both sides.

The single-row deep groove ball bearing 625 -2Z from FAG is suitable for compact designs with limited installation space. With an inner diameter of 5 mm, an outer diameter of 16 mm and a width of 5 mm, this rolling bearing primarily withstands radial loads as well as moderate axial forces. The rings and rolling elements are made from standard rolling-bearing steel 100Cr6. A guided sheet steel cage maintains the correct spacing between the rolling elements. Thanks to the standard radial clearance, the miniature ball bearing runs smoothly under standard operating conditions within a temperature range of –30 to +120 degrees Celsius.

What is the 625-2Z deep groove ball bearing suitable for?

The 625-2Z deep groove ball bearing is primarily used in precision mechanical assemblies and compact drive units. Its cylindrical design, without a flange or groove on the outer ring, allows the bearing unit to be integrated into housing bores in a space-saving manner. Maintenance engineers and designers use these components wherever shafts with a 5 mm diameter need to be supported. The sheet metal cover plates on both sides protect the interior from coarse dirt particles, whilst ensuring the bearing continues to run smoothly.

What advantages do the -2Z cover plates offer with this miniature bearing?

The suffix ‘-2Z’ denotes sheet steel cover plates fitted on both sides, which form a non-contact gap seal. Compared to abrasive rubber seals, these metal covers do not cause any additional friction, which facilitates higher speeds and a lower starting torque. This design is suitable for applications in dust-free to moderately dusty environments. With the standard tolerance class P0 (PN or ABEC 1), the bearing meets common industrial precision requirements for direct replacement in repair and series production.
