Deep Groove Ball Bearings FAG 16044 -C4

The FAG 16044 -C4 single-row deep-groove ball bearing, with dimensions of 220 × 340 × 37 mm and a C4 clearance, offers stable running characteristics under thermal expansion.

The FAG 16044 -C4 deep groove ball bearing is an open, single-row rolling bearing designed primarily for radial loads whilst also withstanding moderate axial forces. With an inside diameter of 220 mm, an outside diameter of 340 mm and a narrow width of 37 mm, this design is suitable for large-dimensioned shaft guides. The rings and rolling elements are made of standard roller bearing steel (100Cr6) and are guided by a sturdy sheet steel cage. Thanks to its seal-free design, the bearing achieves high rotational freedom and can be flexibly integrated into external lubrication circuits.

What are the industrial applications for the 16044-C4 deep groove ball bearing?

This radial ball bearing is particularly well-suited to heavy-duty industrial drives, gearboxes and industrial plant where large-diameter shafts need to be supported. Design engineers prefer to use the open design in enclosed housings where oil or grease circulation lubrication systems are already in place. With a wide operating temperature range of –30 to +200 degrees, the bearing is also designed to withstand thermal stresses. Thanks to the standardised tolerance class P0 or ABEC 1, it fits precisely into housing bores and is designed for combined loads.

What does the C4 bearing clearance mean for your bearing assembly?

The C4 designation indicates a significantly increased radial bearing clearance, which is considerably greater than the normal operating clearance and the C3 grade. This design prevents the rolling elements from seizing up if considerable temperature differences occur between the inner and outer rings during operation, or if tight fits cause the inner ring to expand. Anyone fitting the bearing must also bear in mind the open design without integrated cover plates: contaminants must not be allowed to penetrate the raceways, which is why an external housing seal and a suitable lubrication system must be provided before commissioning.
