English term or phrase: ball rail
"In the center of the deck below can seventeen, we have two double-coiled hydraulic valves. These are for the rail clamp slide box in and out on the left and right sides.
Internally in this manifold, we have a sequence valve. This is adjusted so that the right guide wheels on the jack beam come out and hit the inside of the ball rail at the same time the outside rail hook comes into the ball rail. "

What does "ball rail" mean in this context?
This is a part of a manual for railroad tamping machine.

Many thanks

Explanation:
Rexroth Ball Rail systems were specially developed for use in machine tools and industrial robots calling for compact, rolling-element linear motion guideways. Ball Rail systems are available in various accuracy classes, each with extremely high load capacity and high rigidity.

These space-saving assemblies in 9 common sizes (15mm - 125mm) afford the same high load capacities in all four major planes of load application.

Make up your own compact linear motion guideways from interchangeable standard stock elements...

Rexroth fabricates its guide rails and runner blocks with such high precision, especially in the ball track zone, that each individual component element can be replaced by another at any time. This makes infinite combinations possible within each accuracy class. Each element can be individually ordered and separately stocked. Both sides of the guide rail can be used as reference edges.

Essentially it\'s a platform that sits on a rail and moves along it via machine-precisioned ball bearings.
