Central screw adapter
The central screw adapter enables the fixation of sports vehicles where the rim is held by a central nut.
The central screw adapter is used instead of the thread and rim adapter.
The central screw is reproduced on the rim/hub side and mounted identically. The fixing bearing is then attached to the cone adapter as usual.
The central screw adapters must be designed and manufactured individually for each vehicle type. To do this, we need samples of the central screw or CAD data from the customer.
