Ask DocSk8 (Expert Indoor Skate Building Advice) This forum is different then the other SkateLog forums in that it is not a discussion forum, but rather a place you can ask skate building expert Fred "DocSk8" Benjamin about building and repairing indoor speed, derby, and jamskate quad roller skates.

Default Tighteness of bearings

Hay Doc , should you leave any room for side to side movement when you tighten your bearings or should you just back off enough to get a good free spin . I notice that different people do it both ways but whats your take on this matter ? If you were going to buy new bearings for your own perfsonal use , what would you buy ??

You must not have ANY preload on the bearings, otherwise they roll on the side of the groove all the time.. Not good.. To ensure there is no pre load, make sure you have a tiny bit of wiggle..

If you were going to buy new bearings for your own personal use , what would you buy ??
Qube 8 Ball ceramics.. That is as soon as the become available... I have been rolling some prototypes and love 'em...

When you say wiggle do you mean being able to slightly slip the wheel up and down on the axle or being able to rock the wheel slightly?

Slide back and forth very slightly... All sk8 bearings have a bit of axial play to keep the balls in the center of the groove. If you cannot move the wheel back and forth slightly, the play has been taken up and the balls will not ride in the groove properly..
