Product catalog summary

Overview: The document provides detailed specifications and guidelines for ROSTA rubber suspension units, including types DK-A and DK-S, and various sizes and configurations. It includes technical data, material specifications, and installation recommendations.

Specifications: The document lists various rubber suspension units with dimensions, weight, and material specifications. Units are available in different sizes, with specific measurements for diameter, length, and weight. The units are made from light metal profiles, with options for stainless steel and zinc-plated versions.

Procedures and Recommendations: The document advises against welding on rubber suspensions due to potential damage from heat. It recommends using fixation screws with a minimum strength class of 8.8 and provides guidelines for friction locking and plug-in connections.

Standards and Norms: The rubber suspension units are made from seawater-resistant light metal profiles, coated with water-soluble paint. The document specifies the use of DIN 1725 for material standards.

Torque and Load Data: A detailed table provides torque and load values for different unit sizes, including cardanic and radial deflection, and axial load capacities. These values are measured statically for the standard rubber quality "Rubmix 10."

Rubber Quality and Temperature Range: The document outlines different rubber qualities (Rubmix 10, 15, 20, 40, 50) with corresponding working temperature ranges and characteristics, such as elasticity, torque values, and oil resistance.

Customization and Accessories: The document mentions the availability of customized elements and accessories, such as steel parts and brackets, for specific applications. It also highlights the possibility of custom bores in flange plates and threaded bores in inner squares.

Conclusion: ROSTA rubber suspension units offer a range of configurations and materials to suit various engineering applications, with detailed specifications and guidelines provided for optimal use and customization.
