6.1.2.2.1 Semantic definition

Enumeration of Bearing Types.

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.
