Here our support rails track roller system as a not drilled version:
The rail system SMLFS are constructed in composite construction. A high-precision aluminum body takes on hardened and ground precision steel shafts that serve as tracks for wheels. The special single roll makes for a very stable bond of the steel shafts in the aluminum body. Due to its lightweight design, the system is very well suited for use in handling systems.
It is characteristic of roller guides
-quiet operation
-smoothness
-high speeds
-long travel distances
