The Bosch Rexroth TOLERANCE RING AN45X20 (R081004502) is a robust and versatile component designed for creating fixed and secure connections between machine parts without the need for keyways or other positive-locking connections. This tolerance ring, belonging to the AN type, features circumferential flat edges on its outer diameter, making it suitable for use with a standard nominal shaft. It is crafted from carbon steel, ensuring high temperature stability and resistance to various types of chemical stress. The AN45X20 model has a nominal size of 45mm in diameter (d) and a width (b) of 20mm. It offers an economical installation solution while compensating for differences in thermal expansion among machine elements made from diverse materials. This characteristic enhances the overall durability and longevity of the machinery by reducing stress concentrations at the connection points. Engineered for continuous operation up to a certain temperature with brief peaks at a higher range, the Bosch Rexroth tolerance ring can handle significant transferable torque values, which are detailed in the technical notes provided by Bosch Rexroth. The product's design allows for a large tolerance zone with connecting parts, simplifying the design process and reducing manufacturing costs. In terms of load-bearing capacity, it is important to note that while it can sustain considerable radial loads, pulsating and alternating loads permit considerably smaller values; consulting with Bosch Rexroth is recommended for specific applications. The weight of this tolerance ring is minimal, contributing to its ease of installation and low impact on overall system weight. Overall, the Bosch Rexroth TOLERANCE RING AN45X20 is an extremely cost-effective machine element that provides reliable performance in various mechanical applications where secure connections are required between components subject to thermal expansion or other operational stresses.
