The Bosch Rexroth TOLERANCE RING (R082002002) is a precision-engineered component designed for creating fixed and secure connections between machine parts. This tolerance ring, part of the BN series, features circumferential flat edges on the inner diameter that are intended for use with a unit bore system. The BN20X8 model is crafted from carbon steel, ensuring high temperature stability and resistance to various types of chemical stress. With a nominal size of 20mm in diameter and 8mm in width, this tolerance ring facilitates quick and economic installation while compensating for differences in thermal expansion between connected elements made of different materials. This effectively eliminates the need for keyways or other positive-locking connections, simplifying the design of connecting parts. The product boasts a large tolerance zone with connecting parts, enabling it to accommodate manufacturing variances. The Bosch Rexroth TOLERANCE RING is capable of handling continuous operation temperatures up to a certain degree Celsius and can withstand brief peaks at higher temperatures. It has been designed to transmit a specified torque value and can support a permissible radial load under specific conditions; however, lower values are recommended for pulsating and alternating loads. This low-cost machine element not only offers reliable performance but also provides flexibility in design due to its large tolerance zone. Furthermore, special sizes are available upon request to meet unique application requirements. The product's weight is kept minimal without compromising its capability to maintain a fixed connection under various operating conditions. In summary, the Bosch Rexroth TOLERANCE RING BN20X8 (R082002002) is an adaptable solution that ensures robust connections in mechanical assemblies while accommodating manufacturing tolerances and thermal expansion variations.
