HepcoMotion’s large diameter ring guides, segments and track systems offer unlimited diameters, sizes and high load bearing capacity.

Offers all of the inherent PRT2 benefits – But on a larger scale.  Ring guides, segments, and track systems can be manufactured in any size, with no upper limit on diameter.

Flexible – V edges, flat edges (for roller bearings) and integrated racks can be either internal, external or both, providing more design flexibility to suit the needs of the application.

Design freedom – As with the standard PRT2 system, large diameter track systems can also combine left and right hand bends, to achieve hockey stick or “S” shapes.

Low maintenance – Thanks to HepcoMotion´s V guide technology, the system is low maintenance, robust, hardwearing, and particularly suited to environments where a lot of debris occurs.


  • Internal, external or hardened V edges on both sides to provide an extremely durable running surface
  • Ring guides are manufactured as one piece up to 1.8m, larger rings are composed of segments
  • Optional integrated large mod gear and pinion drive for extremely high driving force
  • Bearings up to 150mm are available as standard
  • Adjustable eccentric bearings make installation simple, accurate and play free
  • Stainless steel rings available as a standard option
  • The open centre can accommodate machine elements, maximising the use of space
