Specifications:
The document provides specifications for PS fixing washers manufactured by CEF Polymeres. The washers are available in various sizes, with dimensions specified for types PS 27*10/20, PS 44*13/30, PS 50*13/34, PS 63*16/41, and PS 95*20/56. Key dimensions include diameters ØA, ØB, ØC, and thicknesses D and E.

Mechanical Properties:
The washers are characterized by their hardness, load capacity, deflection, and maximum load. Hardness is specified in Shore A with values of 45, 60, and 75, with a tolerance of ±5. Load capacities range from 8 daN to 250 daN, with maximum loads reaching up to 1000 daN.

Material and Environmental Resistance:
The washers are made from NR rubber with a bonded inner insert, providing fail-safe operation when used with a washer. They are resistant to oil, grease, and ozone, and are suitable for temperatures ranging from -30°C to +80°C.

Applications and Performance:
The washers are designed for vibration isolation, shock damping, and construction-borne noise isolation. They are suitable for off-road vehicle applications and have a natural frequency range of 10 to 20 Hz.
