Offset Shear Springs |
|
Features / Applications |
Metalastik® Offset Shear Springs are normally used in pairs , fitted at an angle to the vertical axis, thereby loading the rubber in shear and compression and providing three linear modes of flexibility. |
The springs shown on the following pages are a selection from the existing Metalastik® range but other and new designs can be made available for applications with special requirements. |
Preferred rubber hardness (50 Shore) and included angles of inclination are quoted for optimum performance but may be varied to suit particular
application requirements. Horizontal stiffness values vary significantly with vertical load and deflection conditions as indicated in the graphs. |
