For special applications > 40 MPa, we recommend using an H8/f8 tolerance (groove/rod) or selecting other, more suitable materials. Please

contact our experts.

*Only BECA 340.0 profiles are fitted with an O'Ring instead of a V-spring.

* The codes that define the materials are set out in the materials table on the previous page.
