These ultra-high precision ball bearings are designed to withstand all extremes at the track under racing conditions or even just fun racing. The removable polyamid covers enable the ball-bearings to be very easily and comfortably serviced.
(For optimum performance, you should degrease the ball-bearings before use, and also apply a light oil. In the event that the ball-bearings do not turn easily, they should be cleaned and re-oiled.)
A complete set of 12 ball-bearings is available under part number #309053. This set completely substitutes all 10x15x4 ball-bearings on your T1.
