The Bosch Rexroth TOLERANCE RING BN30X12 (R082003003) is a precision-engineered component designed to facilitate a secure and reliable connection between machine parts. This tolerance ring, part of the Type BN series, features circumferential flat edges that lie on the inner diameter, making it particularly suitable for use with a unit bore system. Constructed from carbon steel, this tolerance ring ensures quick and economic installation while compensating for differences in thermal expansion among various materials. The BN30X12 model boasts high temperature stability, allowing for continuous operation up to a certain temperature with brief peaks at higher temperatures. Its design eliminates the need for keyways or other positive-locking connections, simplifying the design of connecting parts. Additionally, it offers resistance to an array of chemical stresses and provides a large tolerance zone, ensuring a fixed and secure connection even under varying conditions. With its nominal size specified as 30mm in diameter by 12mm in width, the BN30X12 model can handle a specific range of transferable torque and permissible radial load. It is important to note that reduced values are permitted for pulsating and alternating loads; users are advised to consult technical notes for precise guidelines. This model stands out as an extremely cost-effective solution for mechanical connections within machines. Special sizes of the TOLERANCE RING can be requested to meet unique requirements. The Bosch Rexroth TOLERANCE RING BN30X12 is an indispensable component when designing machinery that demands reliability, durability, and ease of maintenance.
