The stainless steel ball bearings in ABEC 5 quality ensure that your knobs run smoothly!

The set includes four ball bearings measuring 4x7x2.5 mm.

The high precision stainless steel bearings ensure that your crank knob can rotate smoothly. Ideal for replacing old ball bearings or equipping new knobs with ball bearings that only contain plastic bearings.

What does ABEC mean?

ABEC is a standard that indicates how high the manufacturing tolerance is.
The higher the number, the higher the precision of the manufacturing of the ball bearing and the smoother it is. 
The norm is only given with odd numbers.

This means that ABEC 3 ball bearings are at the bottom, followed by ABEC 5 and 7, which are pretty much the most commonly used bearings. They are usually installed as standard.

Why use tuning camps? 

In general, ball bearings that are installed in the reel at the factory often do not have good rotation properties, as a lot of grease and dust prevent smooth running. 

The stainless steel ball bearings are delivered completely oiled and are equipped with an anti-rubber cover that ensures that the bearings are protected from dirt particles. You can remove this cover for cleaning and oiling.

You can also install the ball bearings without a cover, this way you get a little more speed out of the ball bearings because the friction is reduced.

Long durability

The bearings are oiled by default, but we recommend that every user re-oil the bearings after each season, preferably with Alchemy Oil from Hedgehog Studio or Premium Bearing Oil from Glitch Oil.

This means you can benefit from it for longer and you don't have to maintain the ball bearings as often. Additionally, the whirring of the ball bearings is significantly reduced if you oil them.
Just a drop of oil is all you need to enjoy it for a long time.
