Deep Groove Ball Bearings FAG 6318

The FAG 6318 deep-groove ball bearing, measuring 90 x 190 x 43 mm, offers smooth, stable operation for demanding industrial applications.

With the 6318 deep-groove ball bearing, you get a versatile rolling bearing from FAG for industrial drives and heavy-duty machinery. This single-row ball bearing primarily absorbs radial loads, but also guides the shaft precisely when subjected to axial forces acting from both sides. Manufactured from standard rolling-element bearing steel 100Cr6, this bearing is characterised by its dimensional stability and load-carrying capacity in continuous operation. This provides maintenance engineers and original equipment manufacturers with a standardised, high-quality component.

In which applications is the 6318 deep groove ball bearing used?

Design engineers prefer to use this bearing in general mechanical and plant engineering, as well as in industrial gearboxes and rotating shaft drives. Due to its open design without integrated lip seals, there are no additional friction losses at the sealing lips. This is particularly suitable for applications involving higher speeds, where the bearing is lubricated with oil or grease directly via the housing. The deep raceway geometry ensures an even distribution of load across the rolling elements.

What are the key features of the open design with a sheet steel cage?

The integrated sheet steel cage guides the rolling elements stably and withstands mechanical stresses within a temperature range of -20 to +150 degrees. As no sealing washers are fitted, the lubricant can circulate unhindered and dissipate heat from the contact zone. The standard radial bearing clearance ensures balanced operating clearance under normal operating conditions. When designing this open variant, care must be taken to ensure that the installation point is protected against the ingress of dirt by means of housing seals.
