Introducing the Speed-Spec bearing! These bearings are a big step up from your standard axle bearing at a fraction of the cost!

These bearings are aimed at racers who want a “better steel bearing”, and something that is not as expensive as a ceramic hybrid bearing, but something that is built to the same high standards and tight tolerances normally only found in very expensive bearings.

We call them Speed Spec because they are Spec’d for Speed! Made to the highest standards, specs and tolerances. built to a P5 Precision Tolerance with a C3 Clearance Specification .. for the smoothest, fastest roll. Made with the hardest of steel bearing balls and steel races – full chrome 51200 Steel – the best !

… and with the removable rubber seals – these bearings are easy to clean and re-lube … to keep them running smooth and living a long life.

If you are looking for the best all steel bearing you can get – this is it

when it comes to full steel racing kart axle bearings, there is : ‘good’, ‘better’ and ‘best’ … this is the best.

Sold individually, currently available in 40mm and 50mm sizes.
