Structural Design Considerations

These units are the best for high side forces, are relatively low in height, and are usually the lowest in cost.

Expansion bearings should be mounted with the primary stainless steel sliding surface facing down so as to avoid the accumulation of dirt and debris that can affect the sliding performance of the bearing over time.

However, Cosmec has provided expansion bearings with the stainless sliding surface upwards, and special debris brushes were provided to ensure that the sliding surface was kept clean. Please contact our design team if such bearings may be required on your project.

Fixed bearings may be mounted with any face up.

Slide plate offsets can be provided when specified.

Pot bearings are not designed to take bending moments. They must be provided with even, flat seats. High-strength grout, rubber, or fabric pads are recommended. Leveling blocks or bolts must be removed after erection. Shims, when used, must cover the entire bearing area.

Formwork may be constructed around a bearing for poured-in-place concrete structures. Seal between the bearing and formwork to prevent contamination by laitance or concrete. Offsets should be established in advance.

Pot bearings can accommodate many anchoring systems. While we do not cover those systems here as they are considered to be part of the structural engineering design, suggestions for best compatibility with our bearings will be offered on request.
