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.

Lubrication for maximum performance and corrosion prevention.
Precision illumination thanks to well proven rotary stroke bearings
At any times, optical devices have represented what is technically possible in terms of the quality and purity of the materials that are used and precision when processing the components.
Productivity - steady and reliable
Continuously improved optical components combined with modern light sources, such as lasers and LEDs and powerful image processing software, today provide technical solutions that were unthinkable just a few years ago. Besides precision lenses for science and industrial applications, there are innovative applications for the mass market, such as mobile phone cameras and DVD drives. Laser cutting and laser welding have become firmly established in the industrial production sector.
Almost every optical system comprises mechanical components for positioning of lenses in focusing mechanisms, or to adjust apertures or mirrors in complex beam control systems. This is where the MarMotion rotary stroke bearing demonstrates its strengths. The ball bearing is very compact and has been optimized for use in optics. A special mini-range is available. The precisely adjusted preload ensures an absolutely backlash-free, yet very smooth movement.
In many cases, the tight manufacturing tolerances and precision-machined surfaces enable dry running without lubrication. Stainless steel executions are available on request.
Technical features for innovative designs
- Absolute backlash-free movement: Precise alignment of lenses, apertures and mirrors.
- Stick-slip-free movement: Best repeatability and exact positioning.
- Compact design, mini-range: Requires small installation space and supports miniaturization.
- Very low bearing friction: Smooth movements with minimal driving forces.
- Stainless steel executions for dry running: Maintenance-free operation.
