SCHNEEBERGER UNEAR TECHNCXOGY In 1923 SCHNEEBERGER laid the foundation of what is today global linear motion technology. SCHNEEBERGER standards then made it possible to build linear guide-ways, which in terms of loading capacity, reliability and cost-effectiveness set new standards and soon defined what is today the definitive industry standard. The same principles that were the foundation for our success, informing our way of thinking and acting apply today as previously: the spirit of innovation, a no-compromise approach to quality and the ambition to deliver to our customers products...

SCHNEEBERGER UNEAR TECHNOLOGY Overview of product The following special versions do not apply in respect of every rail cross-section or every rail length. For details and technical information, see chapter 7. (1) There are limitations relating to: - corrosion-resistant steel - coatings - maximum rail length (2) There are limitations relating to: - Maximum rail length (in normal quality as well as in options SQ and SSQ) - Hardness of the steel. This is reduced to a min. 54 HRC, which affects the service life of the linear guideway (3) - The special versions ZG and SSQ are not possible -...

3.4 Slideways In some applications slideways/slide bearings are more suitable than roller-contact bearings. For such applications SCHNEEBERGER produces steel strips, which are produced with a slideway lining selected by the customer (e.g. Turcite B, Glycodur or Ampco) and then re-ground. The slideways can be supplied in standardised dimensions for the roller-contact bearing or on a customer-specific basis too. Flat strips Our linear guideways can be universally deployed, but can also be configured on a customer-specific basis ex works. Amongst other things, SCHNEEBERGER offers the following...

Linear guideway for a tool grinding machine table Precision-grinding on tool grinding machines requires a stickslip-free and frictionless guideway to allow longitudinal movement of the table. Possible SCHNEEBERGER products: 4 linear guideways type R 9-800 2 roller cages AC 9 x 33 rollers 8 end pieces GA 9, GB 9 Table bearing for an internal cylindrical grinding machine Internal cylindrical grinding robots require absolutely zero-backlash table guiding in order to meet the stringent requirements of today's grinding technology. The grinding table displayed is mounted with type N/O linear...

Closed V guideway for surface grinding machines Economic perspectives also determine the structural design of the tables guideways for surface grinding machines. The V-shaped arrangement of the roller guideways creates a closed linear guideway that can be loaded for forces and moments from all directions. The few components ensure rapid and simple assembly. The stroke and table length ratios are optimal for the use of roller guideways. The basic surfaces of the roof-shaped linear guideways can be machined with extreme efficiency and precision because they are on the same plane. These...
