The Bosch Rexroth TOLERANCE RING (R082001251) is a precision-engineered component designed to ensure a fixed and secure connection between machine parts, particularly where there are differences in thermal expansion between elements made of different materials. The tolerance ring, which falls under the BN model code, features circumferential flat edges on its inner diameter that make it suitable for use with a unit bore system. This specific model has a nominal size of 12 mm in diameter (d) by 6 mm in width (b), crafted from corrosion-resistant stainless steel to offer high temperature stability—capable of withstanding continuous temperatures up to certain degrees Celsius and short-term exposure to even higher temperatures. The Bosch Rexroth tolerance ring is not only quick and economical to install but also eliminates the need for keyways or other positive-locking connections, simplifying the design of connecting parts. Its robust composition makes it resistant to various types of chemical stress, ensuring durability and longevity even in harsh environments. The product is noted for its large tolerance zone with connecting parts, accommodating considerable variations while maintaining a secure fit. Engineered for versatility, special sizes can be requested to match unique application requirements. The product's transferable torque capabilities are detailed in the technical notes provided by Bosch Rexroth, which should be consulted to understand the guideline values for free installation scenarios. It's important to note that significantly smaller permissible radial load values are allowed for pulsating and alternating loads; consultation is recommended for such conditions. Lastly, the TOLERANCE RING BN12X6N offers an extremely cost-effective solution as a machine element while maintaining high performance and reliability standards.
