Ceramic Ball Technology: The Sure-Grip QUBE Ceramic Skate Bearings feature high-grade zirconium oxide ceramic balls, designed to deliver enhanced durability. These advanced bearings are ideal for skaters and those seeking high-speed performance, allowing for smooth and effortless rolling even under demanding conditions 8-Ball Design for Stability: The innovative 8-ball configuration of the Sure-Grip QUBE bearings offers increased stability, ensuring smooth and reliable rotation during sharp turns, jumps, and heavy impacts. Unlike traditional 7-ball bearings, the 8-ball design evenly distributes pressure, preventing wear and tear Greased for Efficiency: Sure-Grip QUBE Ceramic Skate Bearings come pre-lubricated to minimize heat buildup during extended use. The grease ensures smooth operation while reducing friction, requiring less maintenance Impact-Resistant Material: Built to endure rough terrain and heavy shocks, the Sure-Grip QUBE bearings are crafted from ceramic, a material renowned for its strength and resistance to deformation Complete 16-Bearing Set: The Sure-Grip QUBE Ceramic Skate Bearings come in a complete set of 16 durable 8mm bearings, compatible with most inline skates, and roller skates. For added security, a signature is required for delivery. For specialized setups like speed skating or park skating, pairing with bearing spacers and washers (not included) is recommended to further optimize performance Engineered for skaters who demand precision and reliability, the Sure-Grip QUBE Ceramic Bearings combine cutting-edge ceramic technology with performance-driven design. These bearings feature high-grade zirconium oxide ceramic balls, renowned for their ability to withstand extreme heat and friction while maintaining consistent speed and reducing wear. The innovative 8-ball configuration enhances load distribution, delivering stability during high-impact maneuvers like jumps, slides, or technical tricks. Unlike traditional 7-ball bearings, this design minimizes load on individual balls, ensuring smoother rotations and extended durability. Pre-greased for optimal heat dissipation, the QUBE bearings require minimal upkeep compared to oiled alternatives, making them a practical choice for skaters who prioritize low-maintenance gear. Ceramic’s innate resistance to shock and corrosion ensures reliable performance on uneven surfaces or during intense sessions. This set includes 16 precision-crafted 8mm bearings, compatible with most inline skates, and roller skates. For specialized setups (e.g., speed skating or park skating), pairing with bearing spacers and washers (not included) is recommended.
