Deep Groove Ball Bearings FAG 635 -2Z

Compact deep-groove ball bearing 635 -2Z from FAG, measuring 5x19x6 mm, with sheet metal end plates on both sides and standard roller bearing steel, for compact shaft arrangements.

The FAG 635 -2Z deep groove ball bearing is a single-row radial ball bearing in a compact miniature design. With a bore of 5 mm, an outside diameter of 19 mm and a width of 6 mm, the bearing primarily accommodates radial loads as well as moderate axial forces. Manufactured from standard bearing steel (100Cr6) with a robust sheet steel cage, the bearing operates within a temperature range of –30 to +120 degrees Celsius. The outer ring has no flange or ring groove.

What is the 635-2Z deep groove ball bearing suitable for?

This miniature deep-groove ball bearing is primarily used in compact assemblies, smaller drives and precision mechanical designs. Wherever shafts with a 5 mm diameter need to be guided precisely, this single-row bearing provides smooth guidance. The covers on both sides protect the interior from coarse dirt particles and foreign bodies. This makes the roller bearing suitable for industrial environments with normal dust levels, where contact-free operation without additional frictional resistance is required.

What advantages do the 2Z cover plates offer over standard radial bearings?

The -2Z version features sheet metal cover plates pressed in on both sides, which act as a non-contact gap seal. Compared to abrasive rubber seals, these plates do not generate any additional frictional torque, which facilitates smooth start-up and high rotational speeds. The standard radial bearing clearance (CN) ensures balanced running clearance at normal operating temperatures. Combined with tolerance class P0 (ABEC 1), this provides a versatile component bearing for standard fits in industry and trade.
