Deep Groove Ball Bearings FAG 626 -2Z

The FAG 626-2Z deep-groove ball bearing, with its compact dimensions of 6 × 19 × 6 mm, offers reliable protection against dirt whilst maintaining low frictional resistance.

The 626-2Z deep-groove ball bearing is a single-row miniature roller bearing designed for compact shaft diameters of 6 mm. With an outside diameter of 19 mm and a width of 6 mm, the bearing primarily accommodates radial loads. Thanks to the deep raceway geometries, it is also suitable for moderate axial forces in both directions. FAG manufactures this model from standard roller bearing steel (100Cr6), which gives the component high dimensional stability under load.

In which applications is the 626-2Z deep-groove ball bearing used?

Design engineers prefer to use this compact deep-groove ball bearing in precision mechanical assemblies and compact small drives. This standardised size proves its worth wherever installation space is limited and rotating shafts need to be guided. Thanks to the cylindrical outer ring without a flange or groove, the component can be fitted precisely into housing bores. A robust sheet steel cage reliably maintains the correct spacing between the rolling elements and ensures smooth running characteristics.

What are the key features of the double-sided cover plate design?

The designation -2Z refers to sheet steel cover plates fitted on both sides, which act as non-contact gap seals. This design shields the bearing interior from coarse dirt particles and dust without causing friction losses or additional heat generation during operation. The bearing is designed with standard radial clearance and is rated for a temperature range of -30 to +120 degrees. This version is manufactured to the standard tolerance class P0/PN or ABEC 1.
