Deep Groove Ball Bearings FAG 6314 -2Z-C3

The FAG 6314 -2Z-C3 deep-groove ball bearing combines dimensions of 70x150x35 mm with cover plates on both sides and a C3 clearance rating for industrial applications subject to thermal stress.

This single-row deep-groove ball bearing 6314 -2Z-C3 from FAG can accommodate high radial loads as well as moderate axial forces in both directions. It is manufactured from hardened standard roller bearing steel (100Cr6) for both the rings and the rolling elements, ensuring dimensional stability during continuous operation. A guided sheet steel cage maintains the balls at a uniform spacing. With key dimensions of a 70 mm bore, 150 mm outside diameter and 35 mm width, the design complies with tolerance class P0/PN (ABEC 1). The cylindrical outer ring has no groove or flange.

What operating conditions can the 6314-2Z-C3 deep-groove ball bearing handle?

The ball bearing is designed for operating conditions involving combined loads and demanding rotational speeds. The component covers a temperature range from –30 to +120 degrees Celsius, making it suitable for a wide range of industrial applications. As the metal cover plates seal against the inner ring without contact, no disruptive frictional heat is generated at the sealing gap. This enables operation at speeds comparable to those of open bearings, whilst the rolling element area remains shielded from external particles.

What is the function of the C3 bearing clearance and cover plates in the 6314 -2Z-C3?

The suffix C3 indicates a radial bearing clearance that is slightly greater than the standard value. This additional clearance prevents the rolling elements from seizing up should temperature differences arise between the rotating shaft and the housing, or should tight fits reduce the clearance once the bearing is installed. The sheet metal end caps on both sides (2Z) protect the raceways from coarse dust and solid particles. This ensures that the bearing chamber remains mechanically protected without any additional frictional resistance acting on the rotating rolling elements.
