- The relationship between the inside diameter di and the outside diameter da has been selected to give the bellows good stability.
- Optimum contraction ratio (l/le).
- Unlike rubber or plastic bellows, leather bellows do not impair the smooth running of the rotary stroke bearing.
- The natural material is resistant to most environmental influences. (Caution should be exercised when using certain coolants!)
