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.
Precision positioning thanks to well proven rotary stroke bearings
More than in any other industry sector, technical progress in semiconductor production is advancing rapidly to produce increasingly finer structures in ever shorter time. Growing demands on the quality of workpieces go hand in hand with the requirement for shorter cycle times.
Productivity - steady and reliable
A rotary stroke bearing is the ideal solution for many applications. The rotary stroke bearing combines precision and rigidity in a unique way with compact dimensions. The large number of balls in the ball cage allows high rigidity in all directions. The precisely set preload ensures zero backlash and reliable rigidity, perfect for fast movements in short cycle times.
Minimal friction due to finely machined surfaces, the best materials and carefully hardened steel ensure a long service life, high level of reliability and low maintenance. Downtimes due to maintenance or repair, which are particularly critical in the semiconductor manufacturing sector, can be reduced significantly.
Materials that enable the use in a vacuum or cleanroom are available upon request.
