Front wheel bearing for TZR250 1KT/2MA for use with captive spacers of 17mm diameter mounting flange.  SKF Energy Efficient (E2) deep groove ball bearings can provide more than twice the service life while reducing energy use and total cost of ownership. Design improvements reduce frictional losses in the bearing by at least 30 percent when compared to the same size SKF Explorer bearing. This results in energy savings over the life of the application.
