Abstract

A piston arrangement and a method for producing a piston arrangement include manufacturing a pair of pistons, each having a head and a foot. The foot of each piston is configured to mesh with the foot of the other piston such that both of the pistons are producible from a single piston blank. The pistons define a piston bore having a generally circular cross section when the piston feet are meshed together, and when the pistons are separated, they define a respective partial piston bore. Each of the partial piston bores is configured to receive a load-bearing element having a generally circular cross section, and each is further configured to surround the load- bearing element for more than 180° of the load-bearing element cross section.
