Frequently Asked Questions

Q: What is the difference between ABEC-1, ABEC-3, and ABEC-5 608ZZ bearings?

A: The ABEC rating indicates the precision tolerance of the bearing. ABEC-1 is a general-purpose grade suitable for skateboards, toys, and hobby applications. ABEC-3 offers moderate precision for power tools and light equipment. ABEC-5 (P5) delivers tighter dimensional tolerances, making it ideal for 3D printers, CNC machines, and applications where accuracy and smooth operation are critical.

Q: Are these 608ZZ bearings compatible with skateboards and inline skates?

A: Yes. The 608ZZ bearing is the most universally used bearing size in the industry. With an 8mm bore, 22mm outer diameter, and 7mm width, they are a standard fit for most skateboard wheels, inline skate wheels, and longboard setups. The ABEC-1 or ABEC-3 grade is typically recommended for skate applications.

Q: What does the "ZZ" designation mean on these bearings?

A: The "ZZ" (also written as 2Z or Z) designation means the bearing has double metal shields on both sides. These shields help keep out dust, particles, and minor splashing, reducing the need for frequent re-lubrication and extending the working life of the bearing in everyday mechanical use.

Q: How many bearings are included in one order?

A: Each pack contains 10 bearings (10pcs/lot), providing excellent value whether you need replacements for multiple wheels or are stocking up for a project build.
