Aluminium Hourglass Sleeve

Aluminium Hourglass Sleeves

Aluminium ferrules provide the perfect way to secure a steel wire rope fitting in place with a tight compression fit.

Size of the ferrule must be compatible with the diameter of the wire rope.

Note: aluminium sleeves are not recommended when using stainless steel cable, use zinc plated or copper sleeves instead.

An aluminum hourglass sleeve is a type of sleeve used in wire rope terminations. It is designed to create a loop or an eye at the end of a wire rope, similar to a ferrule.

The hourglass sleeve is named after its shape, which is tapered in the middle like an hourglass. This shape allows for the sleeve to distribute the load more evenly along the wire rope, reducing stress concentrations that could cause premature failure.

The sleeve is typically made of aluminum, which provides a high strength-to-weight ratio and excellent corrosion resistance. It is commonly used in applications where weight is a concern, such as in aviation and marine industries.

To create a termination using an hourglass sleeve, the wire rope is inserted through the sleeve and then bent back on itself to form the loop or eye. The ends of the wire rope are then inserted back into the sleeve and crimped using a specialized tool to create a secure termination.

Hourglass sleeves are widely used in a variety of applications that require high strength and durability, such as lifting, rigging, and anchoring in marine, construction, and mining industries. They are available in various sizes to accommodate different diameters of wire rope.
