What is a thimble used for?
A thimble is a small metal liner that sits inside a wire rope eye, and it plays a big part in how long that eye lasts. This guide explains what a thimble is used for and how to choose the right one.
What Is a Thimble?
A thimble is a U- or tear-shaped metal insert that lines the inside of a rope loop. The rope passes around the outside, and the thimble protects it from rubbing against the clip or fitting.
What Does a Thimble Do?
-
Protects the rope from friction and wear.
-
Prevents kinking and flattening at the eye.
-
Keeps the eye open so a shackle or hook fits properly.
-
Extends the life of the rope termination.
Types of Thimbles
-
BS464 thimbles: a common British standard for wire rope.
-
DIN 6899 Type B thimbles: a European standard with a reinforced shape.
-
JIS thimbles: the Japanese standard, widely used in marine work.
How to Use a Thimble with Wire Rope Clips
Form the eye around the thimble, then fit wire rope clips with the saddle on the live end. The thimble sits inside the loop and the clips grip the rope outside it. Never clamp directly onto the thimble.
How to Choose the Right Thimble
Match the thimble to the rope diameter and the eye size. A thimble that is too small will pinch the rope; one that is too large will not protect the eye. Check the standard required for your project.
FAQ
