Bearing 6003Z 17mm inside, 35 mm outside

Summary: the ally of your fluidity

The bearing 6003-2Z is a standard piece, but in karting, the choice of quality is decisive. Its dimensions of 17mm (interior) x 35mm (exterior) x 10mm (width) make it the standard for many applications on steering rockets and wheel hubs.

Suffix "2z" means that it is equipped with two metal flanges of protection. This is crucial: it prevents track dust and gum splashes to get inside while keeping the factory grease. A bearing that "scratches" or is seized, it is immediately a peak loss and a kart that becomes imprecise in the front train.

- Why choose a quality 6003-2Z bearing ?

1. Reduction of friction: A precision bearing turns more freely, which releases valuable horses out of turn.

2. Waterproofing "2z": The metal flanges effectively protect the balls against dirt without adding the friction of a rubber seal (heavier and more braking).

3. Increased durability: Made with high strength steels, they support the lateral stresses (turns pressed) much better than low-end DIY bearings.

4. Dimensional precision: A perfect fit on your 17mm axis avoids the game in the direction or in the wheels, ensuring a rigorous front train.

💡 Michel's trick

"The bearings, it's like the engine: if they are dirty, they do not turn! The trick: Never clean your brake cleaner bearings directly, because you are going to hunt the original fat and the bearing will grip. My Pro Council: If your kart stayed stored for a long time, turn the wheel by hand. If you feel a 'hard point' or a metal ball noise, replace it without waiting. A rolling case on the track can destroy your rocket or your hub: it costs a lot more than a new bearing! "

❓ FAQ SEO (Frequently Asked Questions)

Q: Can I ride a 6003 bearing without the "2z" ?

A: The open turn (unprotected) is to be proscribed absolutely in karting because of dust and gravel. You must always use a 2Z model (double metal protection) or 2RS (double rubber protection).

Q: What is the difference with a 2RS bearing ?

A: The 2RS has rubber seals that are totally waterproof, but they create a little more friction than a 2z metal. The 2z is the ideal compromise standard in karting for pure speed.
