Extending service life

S719 .. B (HB ../S) and S70 .. B (HX ../S)

The new S719 .. B (HB ../S) and S70 .. B (HX ../S) angular contact ball bearings are equipped with seals made of acrylonitrile-butadiene rubber (NBR), to keep lubricant in and contaminants out of the bearing. These series are particularly suitable for metal cutting and woodworking machines. Bearings without seals for grease or oil lubrication are also available. To facilitate direct oil lubrication in extreme high-speed applications, the outer ring of open bearings can also be manufactured with an annular groove and two lubrication holes as well as two annular grooves to accommodate O-rings.
