Whether it is the stretch-blow moulding, filling, capping or labelling process, rotary machines have many uses in the food industry. They operate at high speed and can produce as many as 100,000 containers per hour. A slewing ring with integrated teeth as a bearing for a transfer star allows precise guidance and a drive function even for large diameters. The integrated seal prevents the penetration of particles and the loss of lubricant.

The ‘Guide Motion’ range represents Schaeffler‘s historical core, including the linear solutions and bearings that have marked the Group’s evolution. This family includes components designed to handle rotary and linear movements in multiple industrial sectors.

Among these, the slewing rings stand out: large ball or roller bearings which, thanks to their exceptional load capacity, are the preferred choice in the heavy engineering sector. Specially designed for oscillating movements, slow rotary movements and high stationary loads, they reliably absorb axial loads and tilting moments. Thanks to their design, slewing rings can often be reduced to a single bearing in cases where radial and axial bearings are combined. Since this reduces, at least in some cases, the costs and work required for the surrounding constructions, this solution is considered particularly advantageous. Slewing bearings are used in applications where there are heavy loads and high safety requirements and, above all, where it is necessary to withstand slow oscillating and rotating movements. The slewing ring races are produced without teeth, but are also available with internal or external teeth for solutions with a drive. The slewing rings are available in various versions, i.e. as slewing rings with four contact points, cross-roller bearings and Y slewing rings.
