RS PRO Steel External Circlip 2.8 mm Groove, For 3 mm Shaft, 0.4 mm Ring Thickness, Phosphated, 7 mm OD 289-180

The RS PRO 289-180 Steel External Circlip is an industrial-grade retaining ring designed to provide a secure and reliable grip on 3 mm diameter shafts. Engineered for external applications, this circlip features a 2.8 mm groove diameter and a precision 0.4 mm ring thickness, ensuring a tight and durable hold that resists dislodgement under both rotational and axial loads.

Manufactured from high-quality steel and finished with a black phosphate and oil coating, the circlip offers enhanced corrosion resistance for long-term use in harsh environments. The robust construction ensures consistent performance across industrial, laboratory, and service applications where components must be safely held in place on a shaft.

With an outside ring diameter of 7 mm and an external grade A specification, this component is widely applicable in assemblies such as gearboxes, motors, pumps, and machinery where precise component retention is critical. Its compliance with BS3673 ensures that the product meets recognized standards for mechanical fasteners and supports integration with compatible circlip pliers for easy installation and removal.

The RS PRO 289-180 circlip is also suitable for maintenance and repair operations, especially where fast, dependable securing of components is required. The durable finish and accurate dimensions support repetitive industrial use, making it ideal for assembly lines, manufacturing, mechanical engineering, and field maintenance teams.

Applications include mechanical power transmission, fastening bearings or gears to shafts, and any scenario requiring axial location of machine elements. The product's engineered precision and resilience make it an essential component for both OEMs and after-market support.
