从China供应商批发进口608 Rs K2 Skates Ceramic Bearing — FOB条款

The 608 RS K2 is a hybrid ceramic bearing engineered for skate applications, combining chrome steel races with white ceramic (silicon nitride) balls to reduce friction and enhance speed. This 8x22x7mm deep groove bearing is sealed with RS rubber shields for contamination resistance, and is supplied in plastic tubes for wholesale distribution. The design targets inline skates, roller skates and skateboards where durability and low rolling resistance are critical.

Hybrid ceramic bearings like the 608 RS K2 typically offer 30-50% lower friction than all-steel equivalents due to the ceramic balls’ hardness and smoothness, while the chrome steel races maintain load capacity. The white ceramic balls (silicon nitride) are standard for high-performance skate bearings, with typical hardness of 1500-1800 HV and a surface finish of 0.05 Ra or better. The RS rubber shields are a common choice for skate bearings, providing a balance between sealing and low drag.

These bearings are used by competitive skaters and enthusiasts who prioritise speed and longevity, as well as by OEMs assembling high-end skates. The 608 size is a standard metric for skate bearings, compatible with most 8mm axle wheels. Buyers should confirm the ABEC rating if critical for their application, as this listing does not specify one. The plastic tube packaging is typical for bulk shipments, with a gross cartons weight of 23 kg for logistics planning.
