The Lukile 50‑Pcs 608 2RS Bearings (8×22×7 mm, 608RS, Abec‑style) are a budget‑friendly bulk pack of standardized miniature deep‑groove ball bearings designed for skateboards, roller skates, 3D printers, scooters, electric motors, fishing reels, yo‑yos, and small‑machine applications. Each bearing is sealed on both sides (2RS), made from high‑carbon bearing steel, and sized to the universal 608 standard (ID 8 mm, OD 22 mm, width 7 mm), making them ideal for DIY, hobby, and light‑industrial use.

These are not ultra‑high‑end racing bearings, but a reliable, precise, and low‑cost set for when you need a lot of bearings without paying motorcycle‑or‑industrial‑bearing prices.

What These Bearings Are For

The 608 2RS bearings are used in:

• Skateboards & longboards: Wheel bearings for smooth rolling and low rolling resistance.

• Roller skates & inline skates: Wheel‑bearing replacements or upgrades.

• Scooters: Small‑wheel bearings for kick scooters and electric scooters.

• 3D printers & small machines:

  • Idler rollers, belt pulleys, extruder rollers, and small‑motion parts.

• Fidget spinners, yo‑yos, fishing reels, and small motors where low‑friction rotation is important.

Because they’re sealed and compact, they’re also used for prototype builds, RC cars, and hobby‑motor applications.

Key Features

1. Standard 608 Size (8×22×7 mm)

• All 50 bearings are:

  • 8 mm inner diameter (ID).

  • 22 mm outer diameter (OD).

  • 7 mm width.
    This is the standard 608 skate‑bearing size, so they’re drop‑in replacements for most:

  • Skateboard wheels.

  • Skate, inline‑skate, and scooter wheels.

  • Many 3D‑printer and small‑motor parts.

Universal compatibility makes them very handy for repair kits and bulk replacements.

2. 2RS Double‑Sealed Design

• Double rubber seals (2RS):

  • Keep dust, dirt, and moisture out.

  • Help retain lubricant inside the bearing.

This makes them:

• Better than open‑face ZZ‑style bearings for dusty or outdoor use.

• Good for skateboards, scooters, and 3D‑printer moving parts exposed to debris.

3. High‑Carbon Steel & Precision

• Made from high‑carbon bearing steel, giving:

  • High hardness and toughness for light‑to‑moderate loads.

  • Relatively smooth rolling without severe vibration.

• Manufactured to high‑precision standards, so:

  • They spin smoothly and quietly for skateboard and motor‑style applications.

4. Low‑Friction, Long‑Life Properties

• Ultra‑low friction coefficient helps reduce energy loss and wear, which is important for:

  • Skateboards and scooters (more speed and less effort).

  • 3D‑printer rollers and small motors (efficiency without overheating).

They’re not meant for heavy‑duty industrial motors, but they perform well for hobby‑grade applications.

5. 50‑Piece Value Pack

• 50 bearings in one pack:

  • Enough to replace or upgrade:

    • Multiple skateboards, scooters, or roller skates.

    • 3D‑printer idlers or multiple gadgets.

• Cost‑wise, that’s under $0.30 per bearing, making it a very cheap bulk option for:

  • DIY repairs.

  • Prototyping.

  • Stocking up for future builds.

This is ideal for:

• Hobbyists, makers, and DIY‑oriented users who go through bearings frequently.

Pros and Cons

Pros

• Universal 608 size (8×22×7 mm)
  Fits most skateboards, scooters, 3D‑printer parts, and small machines without modification.

• Double‑sealed 2RS design
  Protects against dust and moisture, improving longevity compared to open bearings.

• Good precision and smooth rolling
  Suitable for skateboards, scooters, and light‑motor use.

• Low cost per bearing
  Bulk pack makes it cheap for repairs, swaps, and inventory.

• Versatile for many applications
  From skates and scooters to 3D printers and small motors.

Cons

• Not ultra‑high‑end (no Abec‑9 or ceramic‑ball claim)
  Performance is appropriate for hobby‑grade use, not professional racing or high‑speed industrial motors.

• May not match precision of top‑brand bearings
  Good for casual skating and 3D printing, but not guaranteed for world‑class speed or load‑bearing.

• Sealed bearings are harder to relubricate
  Once the factory grease dries out or gets contaminated, you can’t easily service them; they’re best treated as replace‑when‑worn parts.

Real‑World Use & Expectations

In practice, 608 2RS bearings of this type are:

• Very common in skateboards and scooters—they’re the standard size and reasonably durable for everyday abuse.

• Frequently used in 3D‑printer builds and small‑machine projects because of their low friction and compact size.

• Valued for bulk packs because:

  • Bearings wear out over time from dirt and heat, so having spares on hand is convenient.

  • They’re inexpensive to replace as a system.

For light‑to‑moderate use (skating, scootering, light motors), these bearings generally:

• Spin smoothly when first installed.

• Last hundreds of hours before needing replacement, especially if kept reasonably clean.

Who Should Buy These Bearings?

They’re best for:

• DIY skaters, scooter riders, and roller‑skaters needing replacement or upgrade bearings.

• 3D‑printer builders and hobbyists who need low‑cost, standardized 608 bearings for idlers, rollers, or small motors.

• Prototypers and small‑machine makers using 608 bearings in small machines or gadgets.

• Budget‑conscious users who want many bearings at a low per‑piece price rather than premium‑branded single bearings.

They’re less ideal for:

• Professional racing or high‑speed, heavy‑load motors requiring ceramic or ultra‑precision bearings.

• Users who want serviceable, open‑face bearings they can relube regularly.

Frequently Asked Questions

Are these the same as 608 ZZ bearings?
They’re similar in size (8×22×7 mm), but 608ZZ bearings are open or metal‑shielded, while 608 2RS are double‑rubber‑sealed for better dust/moisture protection.

Can I use these in a 3D printer?
Yes. Many 3D‑printers use 608 bearings in idlers, extruder rollers, or belt pulleys, so these are suitable for such applications.

Are they suitable for skateboards and scooters?
Yes. They’re the standard 608 skate‑bearing size, so they’re widely used in skateboards, longboards, and scooters.

How long do they last?
With reasonable care and avoiding extreme dirt and heat, they typically last hundreds of hours of use before needing replacement, especially in hobby‑grade setups.

Do I need lubrication?
They come factory‑lubricated with grease, so you don’t need to add more unless you specifically want to customize or refresh them (but sealed bearings are hard to service).

Final Verdict

The Lukile 50‑Pcs 608 2RS Bearings (8×22×7 mm) are a versatile, affordable, and reliable bulk pack of standard skate‑style bearings perfect for skateboards, roller skates, scooters, 3D printers, and small‑machine projects. Their double‑sealed design, high‑carbon steel construction, and universal 608 size make them a great “go‑to” bearing pack for hobbyists, makers, and DIYers who need many bearings at low cost.

If you want cheap, dependable, sealed bearings for repairs, upgrades, or prototyping rather than show‑stopper racing performance, this 50‑piece pack from Lukile is a smart, practical choice.
