Wheel spindle (4)

Ross

I believe the answer is:

axle

'wheel spindle' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for axle that I've seen before include "Pin in revolver" , "Rod bearing wheels" , "Shaft with wheels attached" , "Pin on which a wheel turns" , "Bar on which wheels rotate" .)

I've seen this clue in The Mirror, the Penny Press, The Guardian, the Universal and The Times.
