608ZZ 608 2RS 608 Small Ball Bearings For Skateboard

608ZZ/608 2RS 608 Small Ball Bearings For Skateboard are compact single-row deep groove bearings made of GCr15 chrome steel with nylon cages, where 608ZZ features double metal shields for dust resistance and high speed (up to 34000rpm) while 608 2RS has double rubber seals for dust/moisture protection and pre-filled grease, both supporting radial/bidirectional axial loads to deliver smooth, low-noise and durable performance for skateboard wheels.

Technical parameter:

608ZZ/608 2RS 608 Small Ball Bearings For Skateboard share a compact single-row deep groove structure with GCr15 chrome steel inner/outer rings and precision-machined raceways (for stable load-bearing and smooth rotation), lightweight nylon cages that evenly separate steel balls to avoid collision and reduce friction, standardized cylindrical bores for tight shaft fit, and are optimized for skateboard wheel installation—while 608ZZ adds double metal shields for dust resistance and high-speed adaptability, and 608 2RS is equipped with double rubber seals to retain pre-filled grease and block moisture, both balancing radial/bidirectional axial load capacity for skateboarding scenarios.
