Their profits are many and varied that the hole where the axle rotates is displaced 0.6 mm. respect to the plastic anchor. Now you have the possibility of raising the axle position without lifting the chassis and therefore keep the center of gravity lower addition to preserving the motor magnet effect.

Another advantage is the ability to use larger diameter wheels without compromising the height above the track and keeping the lower center of gravity. In the chassis with angled or parallel support motor, in addition to the utilities comment above, new alternatives with the possibility of approximate the crown to the pinion.

TIPS/RECOMMENDATION:

The marks (holes) that are machined on the face of each bushing are used as a positional reference. That is, the bushings, placed in their housing, must match as if they were a mirror. The best example is that of the clock. If, for example, a bushing is placed with the mark -at six- its twin must also be placed -at six-.

It is very important to glue them to prevent them from moving and, according to our experience, the best glue is contact glue. It provides a correct fixation, acts as a "shock absorber" for possible vibrations and allows for easy removal without forcing the plastic anchors.

This glue allows us enough time to place and, if necessary, "reposition" the bushings and for the shaft to rotate correctly and without any impediment.

Compatible with all traditional or 3D plastic supports between 4.6 and 5 mm diameter.

REMEMBER: To ensure the correct performance, reliability and durability of a brass bushing, it is VERY IMPORTANT to lubricate regularly and generously.
