The compact and weight-reducing design of the future´s bearings

Modern design conception requires high technology bearings. KAYDON REALI-SLIM® bearings are designed to create space, save weight, reduce friction and provide excellent running accuracy. REALI-SLIM® bearings are unique, because every series is based on the same cross section, which remains constant with increasing bore diameters.

New Engineering Software by KAYDON®
REALI-DESIGN® and REALI-DESIGN MM™ Engineering Aids for KAYDON REALI-SLIM® thin-section bearings. This innovative program is an actual engineering aid designed to reduce bearing selection time to seconds, to save hours of tedious computations, to determine safe operating speeds, to calculate load deflections and accurately compute essential life and load analyses.

Nowadays linear guides and systems have become extremely important in machine construction. To make designs more economic, the use of these components and systems will increase in future. The priority is the economic technical solution, not just a good technical idea. Linear systems, based on hardened precision shafts as the basis of linear guides, are still very important.

Advantages:

• Totally interchangeable product range
• Precision shafts in different materials
• Linear ball bushings for all fields of use
• Linear slide bushings (ceramic/self lubricating)
• Linear housings and -components
• Customer based solutions

Spindles as ballscrew assemblies and trapezoidal screws. Both types are available in metric and imperial dimensions according to industrial standards. They transform rotational into a longitudial motion or vice versa. Due to the internal ball circulation, the efficiency of the ballscrews is much higher than the trapezoidal screw. Therefore a ballscrew is used in dynamic positioning applications and the trapezoidal screw in slow transporting or clamping applications with low switching periods.

Advantages:

• Rolled, ground and whirled ballscrews
• Totally interchangeable nuts
• Preload and accuracy as requested
• Individual endmachining
• Superfinished for highest loads
• Long service life and smooth running
• Certified and guaranteed
• System integration possible

New: Linear Guideway with Caged Ball

Linear Guideways not only offer low maintenance due to the integrated lubrication system but also a very high stiffness due to four caged ball chains on for each bogie – for very compact constructions even in miniature sizes.

Advantages:

• Low-maintenance
• No additional lubrication required
• Extension of maintenance intervals
• Lubricant saving
• Clean and chemical resistant
• Available as miniature version
• Available with metal coverstripe
• Available with external lubricant tank

The standard design features 4 caged ball rows in order to increase stiffness for a uniform load distribution in 4 directions. Due to the integrated lubrication system maintenance intervals can be minimized.

Extraordinary smooth operation, extremely compact construction and high precision are features of our crossroller guideways. Features that are especially appreciated in medical, biological and semiconductor technologies as well as in the optical industries and which enable numerous new solution approaches.
