Deep Groove Ball Bearings FAG 6301 -C3

The FAG 6301-C3 deep-groove ball bearing, measuring 12 × 37 × 12 mm, offers increased bearing clearance for demanding thermal and dynamic operating conditions.

The 6301-C3 deep-groove ball bearing is a single-row rolling bearing with a 12 mm bore, an outer diameter of 37 mm and a width of 12 mm. Manufactured from standard roller bearing steel 100Cr6, the design is primarily suited to radial loads and moderate axial forces. As an open bearing without integrated sealing washers, this version is particularly suitable for systems with a locally supplied lubricant supply. Manufactured by FAG, the component complies with standard tolerance P0 or ABEC 1 and is suitable for operating temperatures ranging from -20 to +150 degrees.

What is the 6301-C3 deep groove ball bearing suitable for?

This bearing is primarily used in machine units and gearboxes where housing seals or oil-bath lubrication are present. As the bearing is of an open design, lubricant flows unhindered to the rolling elements and the sheet steel cage. Designs with varying operating temperatures benefit from this design, as the inner and outer rings can expand to different degrees during operation without adversely affecting running characteristics. As a result, the unit is used for precise shaft support in general mechanical engineering.

When is the C3 radial clearance recommended for the 6301?

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 thermal linear expansion when the shaft and housing reach different temperatures. This clearance also prevents seizing in tight fits. When designing the system, you should bear in mind that open roller bearings must be protected from foreign particles. A clean operating environment or external sealing elements help to ensure that dirt particles do not enter the raceways prematurely.
