Deep Groove Ball Bearings SKF 16044 /C3

The SKF 16044 /C3 deep groove ball bearing, with dimensions of 220 × 340 × 37 mm and increased clearance (C3), provides a robust bearing solution for industrial drives subject to thermal stress.

The 16044 /C3 deep groove ball bearing is a single-row rolling bearing from SKF that primarily accommodates radial loads as well as moderate axial forces. With a bore of 220 mm, an outside diameter of 340 mm and a narrow width of 37 mm, it is one of the particularly space-saving large bearings. The rings and rolling elements are made from standard rolling-bearing steel 100Cr6. A guided sheet-steel cage keeps the balls at a uniform distance apart and ensures orderly guidance within a temperature range of –20 to +150 degrees Celsius.

What is the 16044 /C3 deep-groove ball bearing suitable for in industrial plant?

This single-row deep-groove ball bearing is particularly well-suited to large-scale industrial applications where shafts with a diameter of 220 mm are supported. Design engineers make specific use of the narrow cross-sectional height combined with a large outer diameter of 340 mm for installation spaces with limited axial width. As this is an open bearing without integrated seals, it can be integrated directly into oil circulation or centralised lubrication systems. The bearing supports radial loads and guides the shaft axially in both directions.

What are the operational benefits of the increased radial clearance (C3)?

The C3 designation indicates a slightly increased radial clearance compared to the standard when the bearing is unmounted. This additional radial clearance compensates for thermal expansion that can occur between the shaft and housing at operating temperatures of up to +150 degrees Celsius. The C3 classification also counteracts stress on the rolling elements when tight press fits on the shaft reduce the radial clearance after assembly. This ensures the bearing continues to run smoothly and helps protect the raceways against premature fatigue. During installation, care must be taken to ensure a clean external housing seal to prevent the ingress of dirt.
