Deep Groove Ball Bearings FAG 6003 -2Z-C3

The FAG 6003 -2Z-C3 deep-groove ball bearing, measuring 17x35x10 mm, features cover plates on both sides and is suitable for elevated operating temperatures.

The 6003 -2Z-C3 deep-groove ball bearing is a single-row radial ball bearing for a wide range of industrial and workshop applications. FAG manufactures this rolling bearing from standard 100Cr6 bearing steel with the compact main dimensions of a 17 mm bore, 35 mm outside diameter and 10 mm width. A robust sheet steel cage guides the rolling elements evenly into the deep raceways. With tolerance class P0 (ABEC 1) and no flange or groove on the outer ring, the unit can be fitted directly into cylindrical housing bores.

In which applications does the 6003-2Z-C3 deep-groove ball bearing prove its worth?

Design engineers and maintenance technicians primarily use this bearing type in rotating shaft arrangements and compact assemblies. Due to its design, the bearing primarily absorbs radial forces as well as moderate axial forces in both directions. The design covers a temperature range from –30 to +120 degrees, making it suitable for industrial drives as well as for DIY repair projects. Even under varying operating conditions, the bearing runs with low vibration.

What do the C3 bearing clearance and the 2Z cover plates mean?

The suffix -2Z denotes sheet metal cover plates on both sides. These gap covers protect the bearing’s interior from coarse particles, but generate hardly any frictional heat compared to abrasive rubber seals. The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional clearance compensates for thermal expansion caused by heat build-up during operation and prevents internal stresses. Before installation, it is advisable to check whether the fits on the 17 mm shaft are compatible with this bearing clearance.
