Deep Groove Ball Bearings FAG 16004

The FAG 16004 deep-groove ball bearing, measuring 20 × 42 × 8 mm, offers a compact design for radial guidance within a temperature range of -20 to +150 degrees.

The 16004 deep groove ball bearing from FAG Rolling Bearings is a single-row radial ball bearing to standard tolerance P0/ABEC 1. It has a bore of 20 mm, an outside diameter of 42 mm and a narrow width of 8 mm. Manufactured from standard rolling-bearing steel (100Cr6), the bearing primarily carries radial loads and also accommodates light axial forces in both directions. The integrated sheet steel cage guides the rolling elements evenly during operation.

What is the 16004 deep groove ball bearing suitable for in operation?

Design engineers opt for the 16004 deep groove ball bearing when radial installation space is limited and a narrow housing width is required. Typical applications include compact shaft and drive designs with a clean lubrication system. As the bearing is open at both ends, it requires a clean installation environment or a sealed housing. In such systems, the rolling bearing can be flexibly integrated into centralised oil or grease lubrication systems.

What are the key considerations regarding the open design and bearing clearance?

This model is supplied without integrated sealing washers and has a standard radial bearing clearance. The internal bearing clearance helps to compensate for minor dimensional changes caused by heating during operation, without generating impermissible stresses in the rolling contact. As there is no contact sealing ring to generate friction, the open design is suitable for low-friction operation. When designing the system, care must be taken to ensure that lubrication is provided by the surrounding unit and that no dirt particles reach the raceways.
