BECA 014
Description
The BECA 014 profile is a polyurethane static seal. It provides an alternative solution to combining an O'Ring (possible twisting during fitting) with a back-up ring (positioning is not always optimal).
Advantages
Excellent resistance to twisting
Easy assembly
Excellent extrusion resistance

Materials
PU
Polyurethane is a material that has the elastic properties of rubber. The proportion in its composition (diisocyanate, polyol, chain extender) is determined by its properties. This material is characterised by a strong mechanical resistance, good wear resistance, high elastic modulus, good flexibility and a very good ozone and oxidation resistance.

Technical data
Preferential extrusion gaps
The mechanical tolerances below are recommended for optimal operation:
- Bore diameter: H8
- Groove diameter: g6
A radial extrusion gap of F/2 at 0.20 mm is acceptable, depending on the shape of the seal and the type of material that makes up the seal.
Surface roughness
| In static radial applications | Ra µm | Rt µm | Rz µm |
|---|---|---|---|
| Contact surface area | ≤ 1.6 µm | ≤ 10.0 µm | ≤ 6.3 µm |
| Groove diameter surface | ≤ 3.2 µm | ≤ 16.0 µm | ≤ 6.3 µm |
| Groove flanks | ≤ 3.2 µm | ≤ 16.0 µm | ≤ 6.3 µm |
