Fresh high-speed ball-bearings produced particularly for XRAY. ID x OD x degree (mm) = 8x14x4. Few 2 pieces. Top-quality expert ball-bearings for a super-free, super-smooth drivetrain. These best value ball-bearings are fitted with original synthetic covers, and are also in addition usually degreased and extremely cautiously full of unique oil for maximum smoothness, longevity, greatest tolerance and maximum performance.
These ball-bearings do have more (and bigger) balls inside the cage versus regular ball-bearings, making them more resilient under loads. The medial component covers are actually very easy to eliminate for quick and comfortable servicing. These ultra-high precision ball bearings are created to withstand all extremes at track under battle conditions or just fun battle. A "must have in reality" product!
