Deep Groove Ball Bearings SKF 16030 /C3

The SKF 16030 /C3 open deep-groove ball bearing, with dimensions of 150 × 225 × 24 mm, can accommodate high radial forces under thermal loading.

The SKF 16030 /C3 deep groove ball bearing belongs to the group of single-row radial deep groove ball bearings with a narrow cross-section. With an inside diameter of 150 mm, an outside diameter of 225 mm and a width of 24 mm, this rolling bearing is suitable for compact installation spaces. Manufactured from through-hardened standard roller bearing steel 100Cr6, the design handles combined loads with precision and low noise. The component complies with standard tolerance P0/PN or ABEC 1.

When is the 16030 /C3 deep-groove ball bearing used?

Design engineers primarily select this size for shaft mountings subject to predominantly radial forces and with limited radial installation space. As the bearing primarily accommodates radial forces and, in addition, moderate axial forces in both directions, it reliably stabilises rotating shafts. The open design, without integrated sealing washers, allows for use in oil-lubricated recirculating systems or enclosed gearbox housings. This enables the lubricant to circulate freely around the raceways and dissipate any frictional heat generated directly.

What are the advantages of the increased C3 bearing clearance?

The C3 designation indicates a slightly increased radial clearance compared with the standard version. This additional clearance between the rolling elements and raceways compensates for operational heating and thermal expansion of the shaft and housing. Even with tight fits, the C3 bearing clearance prevents the bearing from becoming stressed during operation. Together with the robust sheet steel cage, the bearing remains consistently stable within the permissible temperature range of -20 to +150 degrees.
