Huco Aluminium Reducing Bush 10 mm OD, 7 mm Bore, 8.1 mm Length, -50°C to 120°C, Model 257.25

The Huco 257.25 Reducing Bush is a precision-engineered mechanical adapter designed to enable seamless shaft coupling and adaptation. This high-quality component features a 10 mm outside diameter and a 7 mm bore, with a length of 8.1 mm, making it ideal for applications requiring dimensionally accurate bore reduction.

Constructed from robust aluminium, the reducing bush offers a lightweight yet durable solution, resistant to corrosion and suitable for demanding mechanical environments. Its operational temperature range from -50°C to 120°C allows for reliable use in both low and high temperature settings, meeting the requirements of a wide variety of industrial and mechanical systems.

The Huco 257.25 bush is specifically designed for compatibility with components such as acetal fork type universal joints, adjustable friction clutches, nickel bellows couplers, and Uni-lat zero backlash shaft couplers. By adapting the bore size, it expands the versatility of existing hubs and couplers, ensuring a secure and precise shaft fit.

When installed in hubs featuring set screws, the reducer functions as a ring clamp, eliminating the risk of marking shafts during installation and operation. This characteristic is highly valued in systems where repeated removal and repositioning of shafts are anticipated, as the reducer remains securely in the hub and does not require removal or reinstallation with each shaft change. Close tolerance shafts are recommended in order to maintain optimal grip and minimize any risk of slippage.

Applications for this reducing bush include industrial power transmission systems, drive assemblies, automation equipment, as well as laboratory and precision machinery demanding repeatable, non-destructive shaft coupling solutions. Thanks to its meticulous construction and flexible application, the Huco 257.25 is widely adopted in manufacturing, mechanical power transmission, HVAC, and instrumentation setups.

For industrial engineers and maintenance technicians seeking a reliable, long-life solution for shaft adaptation while preserving shaft integrity, the Huco 257.25 Reducing Bush offers excellent performance within its specified dimensional and temperature ratings.
