Deep Groove Ball Bearings FAG 16044 -C3

The FAG 16044 -C3 deep-groove ball bearing, with a 220 mm bore and increased bearing clearance, is designed for mounting on large shaft diameters.

The single-row deep groove ball bearing 16044 -C3 is designed as an open rolling bearing without sealing washers. The rings and rolling elements are made of standard rolling-bearing steel (100Cr6) and are guided by a sheet steel cage. Thanks to the compact design of the 160 series, this component requires comparatively little radial installation space, with an outer diameter of 340 mm and a width of 37 mm. The bearing is manufactured by FAG Wälzlager and complies with standard tolerance P0/PN or ABEC 1.

What loads and operating conditions can the 16044 -C3 deep groove ball bearing accommodate?

This rolling bearing is primarily designed to accommodate high radial forces in conjunction with moderate axial forces in both directions. Typical applications are found primarily in bearing arrangements with large shaft diameters of 220 mm, where radial loads predominate. The open design allows for lubrication via the surrounding housing system, for example through oil circulation systems or manually applied grease within a protected assembly.

What is the function of the C3 bearing clearance during assembly?

The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This feature helps to ensure that the internal operating clearance is not reduced to an impermissible level when tight fits on the shaft or housing cause the inner ring to expand. Similarly, the increased bearing clearance compensates for operational temperature differences between the inner and outer rings. The component is designed for a temperature range of -20 to +150 degrees Celsius.
