I bought a longboard online during COVID. They were super helpful on WhatsApp and answered all my questions. I’m pleased with the board, super good quality and easy to ride. Thank you.

Zealous Bearings - BuiltIn

For a few years now Zealous have been something of a "go to" option for the longboard scene. They offer a great high end bearing at a budget price, keeping you rolling at top speed without having to break the bank.

The builtin spacer feature means you can ditch your separate spacers. No need to do the jiggly wheel thing to line up your spacers making your wheel swaps faster on the uplift bus.

Zealous bearings feature a standard "2RS" rubber shielding arrangement, like Bones Bearings and many other popular brands. They are shielded on both sides so if you destroy a shield whilst cleaning them, you've got a spare if you need it.

Like a lot of bearing brands, Zealous can't resist a bit of extra meaningless marketing:

  • Precision 8mm axle holes - like every other 608 skate bearing, ever
  • .409" built in spacers (that's 10mm for us metric folk) - like all the other built-in bearings in our shop. How the US got to the moon using the Imperial system we will never know...
  • 1mm built in speedrings - again, just like all the other built-in bearings we stock. That's not to say that this isn't a good thing - we don't like loosing speed rings either!
  • Lubed with Archoil Nanoceramic Grease - seriously???? It's just light bearing lube like everyone else uses...

Zealous say: 

"-The unique feature of our lubricant is how the nanoceramic compound fills in deformations or asperities in the bearing. These deformations cause friction and heat around them which hardens the nano-ceramic compound to that specific area. This micro coating is 5 times the hardness of the host alloy and has a molecular bond with the host metal, filling in all the asperities and eliminating friction over time.
-The coefficient of friction is the lowest in the field of Tribology at 0.003% creating a near frictionless surface. Mainly because the nanoceramic compound eliminates all asperities.
-Extremely low water washout
-Corrosion on the inside of the bearing is nearly eliminated."

Whether you believe all the stuff about NanoCeramic wotsits is up to you - despite all the extra marketing hype, we really recommend Zealous bearings, they are used by skaters all over the world and represent seriously good value.

If you want pretty much the same thing with better sealing and easier cleaning, check out the Sabre Built In Race Bearings.

Zealous Bearings

These bearings are about the best you can buy! Not the quickest out of the tube, but after a few hours are super quick and quiet. Combine that with their high speed endurance and these bearings will last you hill after hill, commute after commute. Perfect for longboards and cruisers.

Very happy with these.

Have only had them on for a couple of days but very happy so far. Product information and servicing tutorials very useful, dispatching and delivery impressively swift and efficient. Integrated spacers and speed washers work beautifully.

Great bearings

So useful having built in speed rings and spacers. Means it's so much easier to swap out wheels.
