Deep Groove Ball Bearings FAG 6316 -2Z-C3

The FAG 6316 -2Z-C3 single-row deep groove ball bearing, measuring 80x170x39 mm, features cover plates on both sides and an increased C3 bearing clearance.

The FAG 6316 -2Z-C3 deep-groove ball bearing is a versatile rolling bearing made from standard bearing steel (100Cr6) designed to withstand high radial and moderate axial loads. The design, with an 80 mm inner diameter and a 170 mm outer diameter, is used in numerous industrial drives. Thanks to its single-row design without a flange or groove on the outer ring, the bearing can be easily integrated into cylindrical housing bores. The sheet steel cage guides the rolling elements evenly into the deep raceways.

What loads can the 6316-2Z-C3 deep-groove ball bearing accommodate?

This deep-groove ball bearing primarily withstands radial forces and supports shafts even under axial loads acting from both sides. Designers frequently use this size for cylindrical shaft seats and in applications subject to thermal influences.

With a temperature range of -30 to +120 degrees, the bearing covers typical operating environments in mechanical engineering. The sealed design helps to protect the interior of the bearing from coarse contaminants and to retain the lubricant within the bearing chamber.

What is the function of the 2Z end shields and the C3 clearance?

The metal end plates on both sides (designation 2Z) form a non-contact gap seal. They keep out foreign particles without generating additional friction or heat. This allows for speeds similar to those of an open bearing.

The slightly increased radial bearing clearance (C3) gives the rolling elements more freedom of movement than the standard P0/PN design. This helps to prevent seizing if the inner and outer rings expand unevenly during operation due to temperature differences, or if tight fits reduce the bearing clearance after press-fitting.
