Deep Groove Ball Bearings FAG 6009 -C3

The FAG 6009-C3 deep-groove ball bearing, measuring 45 x 75 x 16 mm and featuring increased bearing clearance, ensures smooth running under thermal loads.

The 6009-C3 deep groove ball bearing is a single-row rolling bearing to standard tolerance class P0/PN, manufactured from standard rolling bearing steel 100Cr6. With a bore of 45 mm, an outside diameter of 75 mm and a width of 16 mm, this open bearing primarily accommodates radial and moderate axial loads. Thanks to its open design, the bearing can be flexibly integrated into existing lubrication circuits using oil or grease. FAG equips this model with a dimensionally stable sheet steel cage, which guides the rolling elements precisely.

What is the 6009-C3 deep groove ball bearing suitable for?

This deep-groove ball bearing is typically used in rotating shaft applications and general mechanical engineering designs. This design is particularly recommended when the housing and shaft have external seals. As the rolling bearing is open at both ends, the lubricant circulates freely between the raceways. The specified temperature range extends from –20 to +150 degrees, making the bearing suitable for applications involving increased operating heat and continuous loads.

What does the C3 bearing clearance mean for this bearing?

The additional designation C3 indicates a slightly increased radial bearing clearance compared with standard bearing clearance. This increased distance between the balls and the raceway reduces the risk of seizing if the inner and outer rings heat up to different degrees during operation or if tight fits reduce the clearance. Design engineers and maintenance personnel therefore specifically select the C3 version for shaft mountings where thermal expansion occurs. As open bearings are sensitive to ingress of particles, a clean installation environment is advisable.
