Design Alternatives

The bearings detailed in the following examples are alternative bearing configurations that are produced by Cosmec and may be used for specialized applications or special requirements.

Center-Guided Expansion Spherical Bearing

It may be used when a lower profile is required. It is used best when horizontal loads are relatively small (less than 20% of the vertical load). Many different low-coefficient-of-friction surfaces are possible, and different configurations are possible for the guide key.

“Inverted” Fixed Spherical Bearing

It can be used when the height of the bearing must be kept as low as possible, such as for rehabilitation projects.

Guided Expansion Spherical Bearing With Bolted Guide Bars

These can be used when removable guide bars are desired.

Spherical Bearings With Uplift Restraints

Cosmec can design spherical bearings with uplift restraints when some uplift is anticipated. One possible configuration is shown. However, many differing configurations are possible.

We can customize bearings as required. Please contact our engineering staff for suggestions.
