item linear guides and accessories
Rollers, bearing units, ball bushing units and cover caps from the item MB Building Kit – for robust linear guides mounted directly on aluminium profiles.
Linear guides in the item building kit
item linear guide components let you build carriages, sliding units and simple handling axes straight from the profile system. Rollers or ball bushings run on shafts that are inserted into the profile groove or fixed with shaft clamps. The result is a smooth, adjustable linear motion without a separate guide rail – moved by hand or automated with toothed belt or spindle drives.
The range covers roller diameters D6, D14 and D25 along with matching pins, bearing units, double bearing units, ball bushing units, wiper and lubrication systems, and cover caps for carriages and clamping blocks.
Selection criteria and versions
- Size: D6 for the compact Line 5, D14 and D25 for Line 8 – depending on load and profile size.
- Bearing unit z or e: concentric (z) and eccentric (e) versions are combined so that the clearance between roller and shaft can be adjusted.
- Single or double bearing unit: double bearing units guide the carriage with two rollers per bearing point for higher rigidity.
- Roller or ball bushing guide: ball bushing units suit compact guides on shafts.
- Protection and lubrication: wiper and lubrication systems keep the running surface clean, cover caps neatly finish carriages and clamping blocks.

Frequently asked questions
What do z and e mean on bearing units?
z stands for the concentric version, e for the eccentric one. Combining both lets you set the rollers against the shaft without play.
Which roller size fits my profile?
The designation includes line and diameter, e.g. "8 D14". Choose components that match the line of your profiles and the expected load.
Do I need a wiper and lubrication system?
It is recommended for dusty environments or frequently moved guides, as it wipes off contamination and lubricates the running surface.
