Deep Groove Ball Bearings FAG 6317 -2Z-C3

The FAG 6317 -2Z-C3 deep-groove ball bearing, measuring 85 x 180 x 41 mm, with cover plates on both sides and a C3 clearance, offers reliable protection and is suitable for high speeds.

The FAG 6317 -2Z-C3 deep groove ball bearing is a single-row radial ball bearing made from standard rolling-element steel (100Cr6) for a wide range of industrial applications. With an inner diameter of 85 mm, an outer diameter of 180 mm and a width of 41 mm, the component primarily accommodates radial loads as well as moderate axial forces. The integrated sheet steel cage guides the rolling elements with minimal vibration. Thanks to the gap covers on both sides, the lubricant filling inside the bearing remains protected, which reduces maintenance requirements during operation.

What is the 6317 -2Z-C3 deep groove ball bearing suitable for in industrial applications?

Design engineers and maintenance personnel primarily use this design for rotating shafts operating at higher speeds and under thermal loads. The design, which has no groove or flange on the outer ring, allows for direct installation in cylindrical housing bores to a standard fit. As the rolling bearing is designed for operating temperatures ranging from -30 to +120 degrees, it is suitable for demanding thermal operating conditions. The design is intended for continuous operation and ensures smooth running.

What are the advantages of the C3 bearing clearance and cover plates in the 6317-2Z-C3?

The C3 designation indicates a slightly increased radial bearing clearance compared with the standard version. This increased clearance compensates for operational thermal expansion of the shaft or housing and prevents the components from becoming stressed in the case of tight fits. The sheet metal cover plates on both sides (2Z) act as a non-contact gap seal. This prevents any additional friction losses, which facilitates high rotational speeds. At the same time, the covers effectively shield the interior from coarse dirt particles and dust.
