608 ZZ Ball Bearings for Roller Skates, Longboards, and Wheels, Suitable for ABEC, Used for Skates, Skateboards, and Scooters, 8 Pieces (8 mm x 22 mm x 7 mm)

【Quantity】: 8 packs of 608 ZZ ball bearing skateboards. (Inner diameter is 8 mm, outer diameter is 22 mm, and overall width is 7 mm). 【High-Quality Materials】: These skateboard ball bearings are made of bearing steel, making them durable, high-speed, and strong. They offer good resistance to deformation under heavy loads, are quiet, and reduce friction. They are suitable for products requiring rotation, low friction torque, low vibration, and low noise. 【Protection】: The sealing material is stainless steel, which effectively prevents external contaminants (dust) and foreign objects from entering the ball bearing and damaging it. Our products are very smooth. The friction limit for grease is 34,000 RPM. The lifespan can be extended by adding a suitable lubricating oil. [Widely used in]: scooter bearings, skateboards, roller skates, skateboard bearings, ball bearing inline skate accessories, toy models, office equipment, micromotors, instruments, laser engraving, small clocks, flexible drives, pressure rotors, dental drills, hard disk drive motors, stepper motors, magnetic drums for video recorders. ►Metal Density: The sealing material is stainless steel, which effectively prevents external elements (dust), foreign matter, and debris from entering and damaging the roller bearing. ►Maintenance-Free: Low coefficient of friction, suitable for high-speed operation, and highly durable. ►Widely Used in: Skateboards, scooters, roller skates, skateboards, toy models, office equipment, micromotors, instrumentation, laser engraving, small clocks, soft drives, pressure rotors, dental drills, hard disk drive motors, stepper motors, and video recorder drums. ►Warm Reminder: After receiving the goods, the bearings are greased. This helps keep the bearings lubricated and reduces friction during transport, making future use more durable.
