SLEWING RINGS AND LARGE BEARINGS

«The higher the stresses, the more strategic the seals and the more appropriate the sealing solutions need to be.»

For 30 years, PXL SEALS has been designing, manufacturing, installing and replacing seals for manufacturers of large bearings and slewing rings.

By putting its expertise and know-how at the service of its customers, PXL SEALS is now a benchmark partner for bearing and slewing ring manufacturers.

In particular, we design, manufacture and install very large diameter seals for a variety of applications.

Sectors using large bearings and slewing rings

PXL SEALS operates in sectors where the performance of seals is strategic.

Slewing ring and large bearing seals are used by large bearing manufacturers and users in the following sectors:

• Energy: seals for hydroelectricity, wind power, renewable marine energy : Wind turbines on the steering ring gear shaft of the nacelle (Yaw) and on the blades of the slewing bearings (pitch).
• Oil & Gas/Offshore: seals for oil platforms : Mobile oil rigs on slewing rings, with which they are equipped.
• Naval and maritime sector: seals for PODs, propellers, radars, defence, etc.
• Public works and forestry machinery: seals for cranes and mechanical equipment : mechanical systems (radars, military tank turrets, forklift trucks, cranes, tunnel boring machines, marine propulsion shafts, etc.
• Construction and civil engineering equipment: sealing for tunnel boring machines
• Industry in general: sealing for industry

These are just some of the applications where sealing is a crucial issue.

We also carry out maintenance on end-customer sites to replace large-diameter joints, whether by moulding, hot-jointing or cold-jointing.

The constraints associated with seals for large bearings and slewing rings

Seals for large bearings and slewing rings are of strategic importance because they have to meet a number of major constraints:

• Very large diameter seals (over 3 metres)
• Vibration
• Resistance over time / durability
• Eccentricity / deflection of parts
• Orientation or continuous movement depending on the case
