The rubber ring spring, known as a low-frequency stud mounting, can be, as shown in Figure 1 (a), stress by three types of loading A, B, and C. The elasticity of rubber ring has different values in the separate directions. It is largest in direction B and smallest in direction A, as shown in the characteristic lines in Figure 1(b). In compressive loading (direction A), the compression may be so large that the hole is completely closed. The description ‘low-frequency mounting’, mean that this rubber ring is suitable for such cases where a low natural frequency is required. It can be loaded up to 100 N per mounting. Thus rubber ring uses lies in the field of precision instrument applications.
