Deep Groove Ball Bearings FAG 16030 -C3

The FAG 16030 -C3 deep groove ball bearing, with dimensions of 150 × 225 × 24 mm and increased bearing clearance, is an open design intended for industrial applications.

This single-row deep-groove ball bearing 16030 -C3 is designed as an open version without sealing washers and primarily accommodates radial loads. Manufactured from standard rolling-bearing steel 100Cr6, the bearing retains its dimensional stability within a temperature range of -30 to +150 degrees. A guided sheet steel cage keeps the rolling elements spaced apart and guides the balls evenly around the raceway. The cylindrical outer ring has no flange or groove, allowing the bearing to be fitted flush into suitable housing bores.

In which applications is the open deep-groove ball bearing 16030 -C3 used?

The bearing is used on shafts with a diameter of 150 mm where radial forces need to be absorbed and axial installation space is limited. As the design does not incorporate integrated seals, the rolling bearing has low rotational resistance. This is particularly suitable for bearing arrangements connected to an external oil or grease lubrication system. The open design requires the housing to be sealed on site to protect the bearing from contamination and lubricant loss.

What is the function of the C3 radial clearance in the 16030 deep groove ball bearing?

The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This increased radial clearance compensates for temperature-induced expansion of the shaft and inner ring during operation. At the same time, tight fits on the shaft reduce the radial operating clearance after installation, ensuring that the bearing does not become stressed. With tolerance class P0/PN or ABEC 1, the component meets the standard precision requirements in mechanical engineering.
