RS PRO Taper Bush, 1610 Series, 30mm Bore, 57mm OD, 25mm Length, Cast Iron, 19.6Nm Max Torque 184-189

The RS PRO 184-189 Taper Bush is a precision-engineered bush from the 1610 series, designed for secure and versatile shaft-to-component mounting in mechanical power transmission systems. It features a 30mm metric bore to accommodate common shaft sizes, with a 57mm outside diameter and a 25mm overall length, providing an optimal fit for pulleys, sprockets, and couplings in both new and retrofit installations.

This taper bush is made from high-strength cast iron, delivering exceptional wear resistance, stability, and mechanical robustness under repeated or high-load operation. Its robust construction and standard 1610 design make it suitable for use in demanding industrial environments, including manufacturing, material handling, agricultural machinery, and HVAC systems.

The bush incorporates a taper locking mechanism and is supplied pre-machined with two set screws, streamlining installation and ensuring a secure connection that resists vibration and slippage. The maximum tightening torque of 19.6 Nm allows for reliable operation even in power transmission assemblies exposed to significant dynamic loads.

Engineers benefit from rapid mounting and dismounting with RS PRO taper bushes, reducing downtime for maintenance and allowing for quick replacements or shaft modifications. The metric sizing and compatibility with standard taper bush pulleys, sprockets, and weld-on hubs simplify selection and integration into existing systems.

Applications include use in V-belt and wedge belt drives, chain sprocket assemblies, couplings, and custom rotary solutions. The unique 4-hole design ensures correct fitment and alignment, supporting precise torque transfer across all shaft-mounted components. Supplied with installation instructions and set screws, this bush is ready for immediate industrial use.

Additional shaft diameter options in the RS PRO Taper Bush series are available separately to accommodate different installation requirements. The 184-189 model is a reliable, field-proven solution for all applications requiring durable, vibration-resistant shaft-to-component connections.
