Combined Bearings

Combined bearings represent a special range both for dimensions and technical features.

They are used both for big size fork lift masts and for different industrial applications in the following fields: ship, aircraft, steel industry.

High load capacity and a limited width represent the fundamental features of this bearing.

Technical Characteristics

Outer ring, axial little roll and little pin are manufacture in 16CrNi4 steel . This kind of material has a very high core resistance and is particularly suitable to endure shocks and to support the applied loads. These components reach a hardness of 60-2 HRC.

The inner ring is manufactured in 100Cr6 steel with hardness 60+2 HRC.
They are normally supplied with seals in ZZ execution. They can also be supplied in 2RS execution on request. Combined bearings are provided with a lubrication system of the radial part.

Also the thrust ring is manufactured in cementation steel.

The central pivot is manufactured in 16CrNi4 steel which guarantees the maximum resistance to fatigue and a good welding.
