Deep Groove Ball Bearings FAG 6018 -Z

The 6018-Z deep-groove ball bearing from FAG Wälzlager has metric dimensions of 90 × 140 × 24 mm and features a single-sided cover plate made of sheet metal.

The single-row deep groove ball bearing 6018 -Z from FAG Wälzlager primarily supports radial loads and guides shafts axially in both directions. Manufactured from standard rolling-bearing steel 100Cr6, this radial ball bearing features a robust sheet steel cage and standard radial clearance. Thanks to the standardised tolerance class P0 (ABEC 1), the component is suitable for precision industrial applications within a temperature range of -30 to +150 degrees Celsius.

What is the 6018-Z deep groove ball bearing suitable for in operation?

Typical areas of application for the 6018-Z deep groove ball bearing include general mechanical engineering, industrial gearboxes and electric motors. Designs with a 90 mm shaft diameter utilise the compact radial height of the 60 series with a cylindrical shaft seat. This rolling bearing is primarily used where one side of the bearing is already protected from contamination by the surrounding machine housing.

What is the function of the single-sided Z-cover?

The metal cover plate on one side protects the raceway against the ingress of coarse particles, whilst the uncovered opposite side allows lubrication via the housing circulation system. As the gap seal is of a non-contact design, no additional frictional torque is generated on the shaft. Together with the lightweight sheet steel cage, the thermal load remains low across the entire temperature range up to +150 degrees Celsius.
