【Sturdy Chrome Bearing Steel Material】This 608zz bearing is made of more quality & higher purity bearing steel, which has higher and uniform hardness and elastic limit than carbon steel.
【More Size Accuracy】Bearing Steel guarrantees the 608ZZ bearing with more accurate size and less allowable tolerance, giving 8 x 22 x 7 mm for ball bearing.
【High Wear Resistance】Bearing steel keeps the bearing works smooth and flat，sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place. Lower wear and tear makes the bearing longer service life.
【Great Rust-Proof Quality】The material of bearing steel makes the bearing have good anti-rust performance in use.
【Multi-Purpose】This 608 bearing is ideal for moderate load uses: skateboards, inline skates, scooters, roller skating, longboard, roller blade, etc.
