The Bosch Rexroth TOLERANCE RING (R082012001) is a precision-engineered component designed for various mechanical applications. This tolerance ring, belonging to the BN series, features circumferential flat edges that lie on the inner diameter, making it suitable for use with a unit bore system. Its specifications include a nominal size of 120mm diameter by 28mm width, constructed from carbon steel to ensure durability and high temperature stability for continuous operation up to a certain temperature, with brief peaks tolerable at higher temperatures. The Bosch Rexroth TOLERANCE RING BN120X28 is crafted to compensate for differences in thermal expansion between machine elements made from different materials, effectively eliminating the need for keyways or other positive-locking connections. This results in connecting parts having a simpler design and allows for quick and economic installation. The ring's large tolerance zone ensures a fixed and secure connection between machine parts even when faced with various types of chemical stress. This tolerance ring is not only an extremely low-cost machine element but also offers flexibility in design due to its ability to provide special sizes upon request. It boasts considerable resistance to chemical stressors and can handle a specified transferable torque and permissible radial load, though it is recommended to consult the manufacturer for guidelines on pulsating and alternating loads. Overall, the Bosch Rexroth TOLERANCE RING BN120X28 (R082012001) is an essential component that offers reliable performance in securing connections within machinery while accommodating manufacturing variances and thermal expansions.
