The Bosch Rexroth TOLERANCE RING AN40X30 (R081004004) is a robust and versatile component designed for securing machine elements without the need for keyways or other positive-locking connections. This tolerance ring, made from carbon steel, features circumferential flat edges on its outer diameter, making it suitable for use with a standard nominal shaft. With dimensions of 40mm in diameter and 30mm in width, the AN40X30 is engineered to provide a fixed and secure connection between parts, accommodating large tolerance zones. The AN40X30 tolerance ring is particularly effective in compensating for differences in thermal expansion between connected components made of dissimilar materials. Its high-temperature stability allows continuous operation up to a certain temperature with brief peaks at higher temperatures. The design ensures quick and economical installation while offering resistance to various types of chemical stress. The product simplifies machine design by eliminating the need for more complex fastening methods and is noted for its extremely low cost as a machine element. Despite its simplicity, it offers high performance with the capability to transfer significant torque while also handling permissible radial loads effectively. However, it's important to note that lower values are recommended for pulsating and alternating loads. Bosch Rexroth provides the option to request special sizes of the tolerance ring to suit specific application needs. The model code AN40X30 reflects a nominal size of 40mm x 30mm, which aligns with the standard dimensions provided by Bosch Rexroth for this type of component. Users are advised to consult technical notes and information provided by Bosch Rexroth when considering free installation or when calculating guideline values for torque transmission and radial load capacities.
