Winkel’s new NbV series of U-profiles is now available in Australia from T.E.A. Transmissions .
Designed to accommodate a 30% higher load capacity than the earlier Nb version, the new series uses profiles with steelgrade S450 J2 mod., which also results in a choice of smaller sizes and higher resistance against wear-out effects.
Due to micro alloying with niobium, the steelgrade S450 J2 mod has a higher tensile and yield strength and a more fine grained structure than conventional S355 J2G3 steelgrade, delivering benefits such as better weldability, higher bearing pressure and higher resistance to brittle fracture. In addition to functional and economical benefits, this design can also save space and weight.
Winkel’s range of U or I profiles is available to suit all sizes of bearings. They are also available in stainless steel, and in lengths up to 12m upon request.
Winkel’s product range is ideal for heavy-duty applications that have very high axial and radial loads. Individual linear/rotary bearings can sustain loads of up to 140kN with jumbo bearing outside diameters of up to 280mm. Fully assembled handling systems with a range of drive options are suitable for loads up to 50 tonnes.
Customer enquiries for individual components or multi-axis handling systems built to exact specifications are welcome.
