Three different type rails - each with a particular raceways shape- are available for this linear bearing system: T, U and K.
The COMPACT RAIL system has been studied to facilitate in mounting and to offer high cost savings on assembly-time. In addition, substantial cost savings is also gained due to low requirement of the accuracy of the mounting surface finish. All rails are cold-drawn carbon steel with races hardened to over60 HRc. The U-Rail offers lateral misalignment compensation and can be mounted together with either a T-rail of a K- Rail. We do not recommend mounting them alone. The T-rail can be mounted alone, or with another T rail or a U-rail. The K-rails have a unique shape that allows them to offer rotational misalignment abilities. They should be mounted with a U-rail.

General Characteristics Material: Carbon bearing steel;
Raceways: Induction hardened to over 60 HRc;
Surface treatment: Electrolytic zinc-plating according to ISO 2081 standard (not present on the raceways). Optional nickel plating
Mountig Holes The rails are supplied in two versions, according to the hole type of the fixing screws. Counter-sunk holes indicated by suffix ..V and counter-bored holes indicated by the suffix ..C. for details). I.e. a size 43 T-rail with ground raceways and counter-bored holes is indicated by the code TLC43.
Raceways Precision Grade The rails are supplied with ground raceways.
The sliders NT, NU and NK are equipped with
rollers which are alternately in contact with the
two raceways.. The second letter of the code identifies the corresponding rail.
The sliders CSW and CDW are equipped with
three, four, five or six rollers, arranged as
follows (as shown in the figure, the fixed rollers
are identified by a “o” symbol stamped on the
bar in connection with the fixed rollers)
CDW sliders have a top mount option.Correct preload setting is very important to the quality of movement and to the lifetime of the system. Normally the sliders are supplied mounted and preloaded in the rails. When supplied separately, the preload must be set by the user. This simple operation must also be carried out if the slider is removed from one rail and mounted in another.
COMPACT RAIL sliders offer a complete range of mounting possibilities. In fact, NT, NU, NK and CSW sliders give the possibility to fix the moving element to the lateral side. In addition, N. 63 can be fixed from behind. CDW sliders have wider body to allow for top or bottom side mounting.
