Product designations The Explorer bearings retain the desig- nations of the earlier standard bear- ings, e.g. 22218 E or BS2-2210 C-2CS. However, each bearing and its box is marked with the name EXPLORER, so that there can be no confusion. The result: longer bearing life

Product dataNew performance class All these improvements contribute to a significant increase in bearing service life and reliability. This can best be shown through calculation using the SKF Life Method. The properties of SKF Explorer spherical roller bearings are taken into consideration by •increased basic dynamic load ratings and •an increased life adjustment factora Page ............. 18Page ............. 32 Availability The popular small and medium size spherical roller bearings in the series 213, 222, 223, 230, 231, 240 and 241 are available as Explorer bearings. The range is being extended in these bearings series as well as in other series.In the product table, the Explorerbearing designations are printed in blue.

Existing machine New machine with same power

Switching to Explorer bearings give•several times the service life previously achieved,•more machine uptime, •higher safety factor, •an appreciable reduction of machine cycle costand, therefore, added value. Explorer makes it possible to use a smaller bearingsize which allows• more compact machines,•higher speeds,•smoother and quieter running, •less lubricant usage,•reduced friction,and will create added value.

The higher carrying capacity ofExplorer bearings allows the use of a lighter series with same outside diameter and increased bore diameter, so that•a stronger, or even hollow shaft can be used,•the total design can be stiffer and also cheaper, •system life is increased due to higher stiffness,and machine cycle cost is significantly reduced. 13
