Material Specifications
Polyetherurethane buffers are characterized by a hardness of 65 - 75 Shore and can operate within a temperature range of -40°C to +80°C, with short intervals up to +110°C. They are resistant to oil and grease.

Applications
These buffers are suitable for use as end stops in traverse cranes and elevators, and can also serve as machine feet. They are effective in absorbing shock due to their high compressibility but are less effective for isolating dynamic forces from vibrating machines. It is crucial not to exceed the maximum compression force.

Performance Data
The document provides detailed performance data for different buffer sizes, including compression at maximum force (F-max), end force at 75% compression, and work at F-max. The data is presented for various sizes ranging from 80mm to 200mm in diameter, with corresponding item numbers.

Graphical Data
Several graphs illustrate the relationship between deflection (in percentage and mm) and load (kN), as well as work (kNm) for different buffer sizes. These graphs help visualize the performance under static conditions and at speeds of 1m/s and 2m/s.

Key Considerations
Ensure that the maximum compression force is not exceeded to maintain the integrity and performance of the buffers. The data provided should be used to select the appropriate buffer size and type for specific applications.
