Pivot points play an important part in rear-suspension design
A leading manufacturer of full-suspension mountain bikes has developed one of its most innovative bikes to date. Triple-butted tubing gives added strength to the joints, while the carbon-fiber frame is lightweight, corrosion resistant, and strong.
On the two front pivot points, between the swing arm and the frame, deep-groove ball bearings are used, because the bearings have to execute a relatively large swiveling motion. At the rear joint, on the rear axle, an iglide® J plastic bushing from igus® has been implemented.
The plastic bushing has a much larger contact area than a roller bearing. This means that, even under extreme stress and lateral forces, it doesn’t wobble.
