941015 Xray Ball-Bearing 10X15X4 Rubber Sealed - Oil (2)

Set of 2 pieces.

Top-quality professional ball-bearings for a super-free, super-smooth drivetrain. These highest quality ball-bearings are fitted with special rubber covers, and are degreased and lightly oiled with AeroShell Fluid 12 oil for maximum smoothness, long life, highest tolerance and maximum performance.

These ball-bearings have more (and larger) balls inside the cage than the regular ball-bearings, making them much more resilient under loads. The side covers are easy to remove for quick and comfortable servicing.

These ultra-high precision ball bearings are designed to withstand all extremes at the track under racing conditions or even just fun racing. A must have item!
