Upgrade your fingerboard wheels with professional-grade bearings for smoother grinds, faster rolls, and consistent performance.
寸法:
Inner diameter (d): 1.5 mm
Outer diameter (D): 4 mm
Width (B): 2 mm
Material: High-grade GCr15 chrome steel – fully hardened (HRC 60–65) for wear resistance and dimensional stability
Rolling Elements: Precision-grade chrome steel balls (Grade G10 or better) – spherical accuracy ensures smooth, low-friction rotation
Cage (Retainer): Miniature stamped steel or nylon retainer – maintains consistent ball spacing without adding excessive drag
Shields: Double metal shields (ZZ design) – non-removable shields prevent dust, lint, and debris from entering the bearing while retaining lubricant
Precision Grade: ABEC-3 to ABEC-9 equivalent – sufficient for the high rotational speeds and light loads of fingerboarding
