Special bearings for the frame, especially for all-terrain mountain bikes, in the link mechanism supporting pivot or rocker arm, in addition to maintaining the frame centerline offset and the radial or axial stress that may be generated by the operation, the strength is very important. Rigidity, in order to overcome the possible impact of various terrains, and even the risk of structural damage, is a component that pays attention to safety factors. Therefore, we specially developed and designed the "V-shaped" full-ball type bearing, which is installed at the structural position of the turning point to support such a key role, increase and strengthen the load of the bearing by 30-40%, and the service life durability problem is solved Improvement, whether it is the driver's own complex stunts or the severe road conditions, can withstand the challenge.

As far as the structure design of the front and rear triangle turning point of the frame is concerned, the spindle size of the connecting rod structure ranges from 8MM to 20MM. The 68/69 series of deep groove ball bearings account for the majority, and we have also developed a variety of non-standard types for customers ( Full ball, flange, convex circle, double row... etc.), which makes the structural design more ingenious, and the function and performance are more balanced. On the subject of rust and corrosion resistance, we also continue to innovate and develop more suitable materials, and apply high-strength surface treatment methods. Satisfy customers and upgrade products.
