Enumeration of Bearing Types.
6.1.2.2.2 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. |
