Bearing solutions for continuous casting plants - the CoCaB range now includes large spherical plain bearings with plastic plates

For decades, Schaeffler has offered rolling bearing and service solutions for use in plants and applications for producing and forming steel and nonferrous metals. The Continuous Caster Bearing (CoCaB) range is customized to suit the requirements of continuous casting plants and includes ELGES large spherical plain bearings for ladle turret lever arms, full complement FAG cylindrical roller bearings, open and sealed FAG spherical roller bearings for strand guide rolls, and INA needle roller bearings for the rolls used in the upper sections of the continuous casting plant. Split FAG spherical roller bearings and INA cylindrical roller bearings are available for installation in driven rolls. The CoCaB range has now also been expanded by the addition of ELGES large spherical plain bearings with plastic plates. The glass fiber reinforced plastic (GRP) contains PTFE additives and, just like bearings with the proven ELGOGLIDE sliding layer, these bearings provide a very long operating life. Special FAG bearing housings with circulating cooling water complete the CoCaB product range.

ELGES spherical plain bearings for ladle turrets

ELGES spherical plain bearings have been successfully used in ladle turret lever arm steering systems worldwide since 1975. Depending on the turret size, the nominal dimensions range from 180 mm to 600 mm. The bearings, which swivel and are subjected to a unilateral load, can fully demonstrate their advantages under these conditions: They have a high load carrying capacity, a space-saving design, and are maintenance-free. The most important of these advantages - the extremely long bearing operating life - is due to the high-performance sliding materials and the optimum product design.

The maintenance-free ELGOGLIDE sliding layer is made from PTFE fabric with support fibers that is embedded in a resin matrix and bonded with high strength to the steel support body. The advantages of bearings with ELGOGLIDE are their total freedom from maintenance and very high load carrying capacity, especially in the case of very high unilateral loads and swiveling motion. The optional ELGOGLIDE W11 variant allows particularly low-friction sliding even at low pressures.

The ELGES family of large spherical plain bearings has now been expanded to include a design equipped with plastic plates. The glass fiber-reinforced plastic (GRP) contains PTFE additives and also provides a very long operating life. The bearings have initial lubrication when delivered, an occasional relubrication extends the operating life even further. These bearings are therefore very easy to maintain.

Depending on the individual application, both sliding materials - ELGOGLIDE and plastic plates - can be used in ladle turrets. Schaefflers application engineering specialists are on hand to assist you in selecting and designing the correct bearings.

In addition to radial spherical plain bearings, the CoCaB range also includes axial spherical plain bearings. These are used in the bearing supports of the hydraulic cylinders that are responsible for steering the lever arms in ladle turret applications.

The option of reconditioning is also available for both the ELGOGLIDE and glass fiber-reinforced plastic baseplate versions, which allows the bearings to be restored to virtually new condition.
