High-quality metrology for quality control in the measuring room, production, incoming goods and development.
Gear Metering Pumps & Meter Mix Dispense Machines with highest accuracy for processing liquids and pastes.
High-precision rotary stroke bearings for backlash-free linear and rotational movements for use in machine and device construction.
Ball-bearing guides for linear and rotational movements without play for use in all technical areas where reliability and precision are required.
The guide diameter finely honed to ISO tolerance IT 3 guarantees the preload of the ball bearing guide in combination with shaft diameter ISO-h3.
Universal, slim inner bevels on both sides.
Permanently installed thrust washers on both sides provide a safe travel limit for the ball cage.
Permanently installed thrust washers on each side and sealing rings prevent impurities from getting into the ball bearing guide.
Extra sturdy model with scrapers on both sides which reliably prevent impurities from getting in, even in very dirty environments.
Universal, slim inner bevels on both sides, for use with ball cage from mini series N502.
Permanently installed thrust washers on both sides provide a safe travel limit for the ball cage from mini series N502.
The balls can move easily without getting lost. The balls are arranged in such a way that they run smoothly and ensure a long service life of the ball bearing guide.
Excellent dry run properties and maximum smoothness, even at high accelerations thanks to the lightweight plastic.
Versatile with balls arranged along a helical line, ideal for linear movements and rotational movements.
Smaller balls used with same shaft diameter compared to type N501. Reduced installation space thanks to guide bushes from the mini series.
High loading capacity thanks to large number of balls, reliable travel limit for the cage thanks to the securing ring.
The finely-ground surface is ideal for high precision ball bearing guides, ensuring smooth running and a long service life of the ball bearing guide.
Preload is guaranteed when using with Mahr guide bushes and ball cages.
Inner thread on both sides, preload is guaranteed when using with Mahr guide bushes and ball cages.
Broader and more optimized range of uses.
Protect open ball-bearing guides against dirt without compromising smooth movement.
Lubrication for maximum performance and corrosion prevention.
Guide Bush N552
Art. no. 5003043
- Stop rings fixed on both sides.
- The closed guide bush and integrated ball cage form a separate component.
- Guide bore diameter d1 is finely honed to ISO tolerance IT 3, Rz 0.5 – 1.5 μm depending on diameter.
- Roundness within 1/3 ISO-IT 3.
- Cylindricity within IT 1.
- Radial run-out of a shaft inserted under preloading is within 0.0005 mm.
- Outside diameter dB n4 with radial run-out error within IT 4, ground to guide bore diameter d1, lead-in taper on one side.
- The maximum stroke path Hmax is determined from the length of guide bush l3 and the length of the ball cage l2: Hmax = 2 (l3-l2).
- See catalog page 37-41 for instructions on installation and servicing.

Einpressen vermeiden!
Durch Einpressen wird der mit sehr hoher Genauigkeit gefertigte Führungsdurchmesser d1 verformt. Die Buchse passt sich der Aufnahmebohrung an. Formfehler und erhöhte Vorspannung sind die Folge. Die Funktion der Kugelführung wird auf jeden Fall negativ beeinflusst.Befestigung der Führungsbuchse
