XRAY High-Speed Ball-Bearing 10 x 15 x 4 Blue Covered (12)
XRA309055
New high-speed ball-bearings in 10x15x4 blue covered manufactured specially for XRAY. Top-quality professional ball-bearings for a super-free, super-smooth drive train.
These highest quality ball-bearings are fitted with special polyamid blue 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 blue polyamide 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!
These new high-speed bearings are substitutes for 309053 HQ Ball-Bearing 10x15x4 Blue Covered (12), as these are already degreased and oiled for higher speed.
