Isambard Kingdom Brunel and Robert Stephenson both made their fames and fortunes using two rails and four wheels. Could you make yours? Euro-Bearings says that the concept of its combined roller bearings and mating steel profiles is just as simple as that of the railways that Brunel and Stephenson built.

Taking a leaf from their book, here is how you could make your money (and possibly your fame and fortune): applying your imagination to this fundamental mechanical solution: two rails and four combined roller bearings which can and do solve many heavy duty linear guidance problems in many diverse industries and environments.

One advantage the combined roller bearing has over the railway wheel or any other wheel for that matter, is the inclusion of the axial roller which runs on the web of the C or H section steel rail and provides a positive resistance to crabbing movement, which is the bane of many linear systems. And the system can be used both vertically and horizontally and will accept cantilevered loads and telescopes and positively adores harsh environments.
