Huco Brass Reducing Bush 4 mm Bore Diameter 5 mm Outside Diameter 4.3 mm Length 251.18

Huco 251.18 Reducing Bush is a precision-engineered brass bore reducer designed to adapt bore sizes in mechanical power transmission systems. Featuring a 4 mm bore diameter, 5 mm outside diameter, and length of 4.3 mm, this component provides a compact solution to increase diameter options for shafts and hubs.

The metal bore reducer functions effectively as a ring clamp when installed in hubs with set screws, preventing damage or marking to the shafts.

Its design allows shafts to be removed or repositioned repeatedly without disturbing the reducing bush, which remains securely fixed within the hub. For optimal grip and reliability, it is recommended to use close tolerance shafts that provide sufficient contact area with the bush.

This product operates reliably within an extended temperature range from -40°C to +85°C, accommodating various industrial and mechanical environments. The brass construction ensures durability and resistance under operating conditions between -20°C minimum and 60°C maximum, providing stable performance in demanding scenarios.

Durable brass material construction enhancing longevity and reliability. Compact dimensions facilitate ease of integration into assemblies. Optimized for critical mechanical power transmission uses. Prevents shaft marking with ring clamp function when set screws are applied.

Supports repeated shaft repositioning without bush displacement. Suitable for universal joints, friction clutches, and zero backlash couplers. Wide operating temperature range enabling use in diverse conditions. Manufactured in the United Kingdom to high quality standards.

This Huco Reducing Bush is a critical component in industrial mechanical systems, fluid power applications, and precision machinery requiring reliable and adaptable shaft coupling solutions.
