6.1.2.3.1 Semantic definition

Enumeration of Bearing Types.

6.1.2.3.2 Type values

Type Description
CYLINDRICAL

The bearing functionality is provided by cylinder in a concave cylinder.

DISK

A disk bearing consist of an elastomeric disc between two metal plates.

ELASTOMERIC

A pad bearing which carries vertical load by contact stresses between a sheet of sliding material and a mating surface that permits movements by sliding and accommodates rotation by deformation of the elastomer.

GUIDE

A bearing that ensures that the structure maintains the correct location or expansion/contraction path and takes no vertical load. Includes also restraint bearings.

POT

A bearing which carries vertical load by compression of an (elastomeric) disc confined in a (steel) cylinder and which accommodates rotations by deformations of the disc.

ROCKER

The bearing functionality is provided by a rocker construction. Includes line rocker and point rocker bearings.

ROLLER

The bearing functionality is provided by one or more rollers that are placed between two plates.

SPHERICAL

The bearing functionality is provided by convex dome in a concave basin.

USERDEFINED

User-defined bearing element.

NOTDEFINED

Undefined bearing element.
