This 10-pack of 608rs ball bearings works well for projects that need smooth, low-friction movement. Each bearing is 8x22x7mm and has deep grooves to support both radial and axial loads. People often use them in skateboards, scooters, and 3D printers.
Features and Benefits
- Double rubber seals (2RS) - The 'rs' means a rubber seal is on each side, keeping dust and moisture out of the inner race.
- Pre-lubricated interior - It comes ready to install with grease inside, so it runs smoothly right away.
- Carbon steel construction - This material handles loads well and resists wear for steady use in different machines.
- Standard 608 size - The 8mm bore, 22mm outer diameter, and 7mm width fits many common uses.
Applications
- Skateboard and inline skates: Replace old wheel bearings to get a fast, smooth ride again.
- 3D printers and CNC machines: Use them on linear rods and filament rollers for accurate, low-drag movement.
- Small motors and fans: Install them in electric motors, cooling fans, and other small spinning devices for quiet running.

They have an 8mm inner diameter for the axle, a 22mm outer diameter, and a width of 7mm.. Q: What do the 'ZZ' and 'RS' in the description mean for construction? A: A 'ZZ' or '2Z' bearing has two metal shields, one on each side, to protect against dust and larger debris. 'RS' or '2RS' means it has rubber seals, which offer better protection against moisture. This pack includes the 'ZZ' metal-shielded type.. Q: Can I use these for things other than skateboards? A: Absolutely. While they're a common size for skateboards and inline skates, you can also use them in 3D printers, small electric motors, fans, and other machines that need a bearing with these 8x22x7mm dimensions.. Q: Is there any kind of performance guarantee or warranty? A: We guarantee these bearings will be free from manufacturing defects when you receive them. However, their lifespan depends entirely on the application, load, and maintenance, so there's no long-term performance warranty.. Q: What makes this 10-pack a good deal? A: You get ten bearings, which is enough to replace all eight in a skateboard and still have two spares. Buying them in a pack like this is much more cost-effective than purchasing them one or two at a time..
