  ZWICKER Precision Deep Groove Bearings  

The single row radial contact ball bearing is the most common rolling bearing. Besides the type series in compliance with boundary dimensions according to ISO 15, ball bearings other than the given values are also produced as miniature bearings, pulleys, wire alignment ball bearings and more special bearings. Further, there are ball bearings in inch measurements in our program, which are oriented towards the ABMA/ANSI – boundary dimensions. Single row metric radial contact ball bearings according to DIN 625 are produced as series 617…618…619…60…62…and 63… A comparison between the constructed sizes is shown in the chart above.

Being a German manufacturer of quality products, Zwicker has focused its business on the demands of its clients. A few special products emerged from close co-operation during products planning, which offer customers crucial advantages concerning carrying capacity, endurance, temperature stability and reliability of their products. No matter if bearing pairs, multiple arrangements, special bearings made out of special materials or bearing units ready for application, for many customers, Zwicker has been an essential partner for decades if small or medium batch sizes in highest quality are of concern. Some of these special types have become a part of the catalogue program because of high market demands, such as track rollers with an outside diameter up to 62mm and wire straightening ball bearings R6, with an outside diameter up to 47mm. These have a 90 Deg. annular groove by default but are also available with ground radii and other special designs on demand.
For the choice of the proper bearing, you can take advantage of Zwicker's application engineering service.
