DO-A

Product catalog summary

Overview: The document provides detailed specifications and guidelines for ROSTA rubber suspension units, specifically the DO-A series. It includes technical data, material specifications, and installation recommendations.

Specifications: The document lists various types of DO-A rubber suspension units with dimensions, weight, and part numbers. Key dimensions include diameter, length, and weight, with specific tolerances provided for each measurement.

Material and Construction: The units are constructed from light metal profiles, with options for stainless steel or zinc-plated versions. The document advises against welding on rubber suspensions due to potential damage from heat.

Torque and Load Capacities: A detailed table outlines the torque and load capacities for different sizes of suspension units, including nominal size, torque, deflection, and load values. These values are based on the standard rubber quality 'Rubmix 10'.

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

Installation and Usage Recommendations: Recommendations include avoiding welding on rubber suspensions, using fixation screws of minimum strength class 8.8, and ensuring proper friction locking by removing paint cover on the face side. The document also provides guidelines for plug-in connections and advises on the use of bright steel for square profiles.

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 availability of special elements with different housing lengths and inner square configurations.
