Customized Solutions
The catalog table section covers spindle bearing solutions of standard envelope dimensions. In the area of customized special solutions, optimal application solutions are shown with ordering nomenclature that make adapting spindle bearing products to the spindle installation situation as simple as possible. Products remain standard sizes and can be used in new designs as well as in existing spindle designs without any problems. According to the type designation system, the basic bearing type remains in the ordering designation. This allows for special solutions that were thought of during the series conception, these being speed, flexibility and uninterrupted service. In addition, any individual bearing designs are available as special solutions (serial number) upon request.

Spring preloaded non-locating bearing units ..SPP Spring Preloaded non-locating bearing units (SPP) are standard Spindle bearings with a doublewidth outer ring. All tolerances of this bearing correspond to P4S. In addition, locating bores for Spiral springs and an anti-rotation locking device are provided on the outer ring, whereby a ready-to-mount

spring preloaded unit is provided. Spring preloading force can be individually set with adjustment of the Springs and by changing the number of springs supplied. The outer ring has thin layer chromium Plating, as standard, and therefore ensures a secure sliding function of the bearing. The sliding function of the spring preloaded non-locating bearing unit is furthermore supported by the increased bearing width.
