Track roller guides are available with various carriages. There are hollow chamber (LFCL), compact (LFKL), open (LFL), floating bearing (LFLL), and swivel bogie track carriages (LFDL). Using these carriages, track roller guides can be easily constructed to operate in contaminated environments. For example, the closed design protects the track rollers from dirt. Additionally, integrated lubrication units are included.
The carriages run without play on all INA guide rails and are combinable with all guide rails of the same size series, except for the round-arched rail. With the concentric (LFZ) and eccentric (LFE) journal designs, the track roller guides are adjustable without play. The track rollers (LFR) feature gap seals on both sides and are lubricated for service life. Oiled lubricating felts are used to lubricate the raceways. Corrosion-protected designs are also available.

- Guide rail with full profile (LFS)
- Guide rail with hollow chamber profile (LFS..-C)
- Flat guide rail (LFS..-F)
