Specifications: The document provides a detailed list of cylindrical fenders with varying dimensions. Each fender is identified by a code (e.g., Y150, Y200) and specified by its outer diameter, inner diameter, and length. The lengths vary significantly, with some fenders having a range (e.g., Y150 has a length range of 500-30000).

Dimensions: The outer diameters range from 150 mm to 2000 mm, with corresponding inner diameters ranging from 75 mm to 1000 mm. The lengths are specified for certain models, indicating flexibility in application.

Performance Specifications: The document outlines the rated compression performance of each fender model, detailing the reaction force and energy absorption capabilities. The reaction force is provided in kilonewtons (KN) for both standard and high reaction force scenarios, with a tolerance of ±10%.

Energy Absorption: Energy absorption is measured in kilonewton-meters (KN-M), with values increasing alongside the size of the fender. For example, the Y150 model absorbs between 1.5 and 2.3 KN-M, while the Y2000 model absorbs between 321 and 584 KN-M.

Customization: The document notes that custom sizes are available, indicating flexibility in manufacturing to meet specific requirements.
