Integrated bearing mechanism is "tops" for BMW
An integrated high performance bearing and threaded shaft has proved the ideal solution to the challenge of creating a robust closing mechanism for vehicle soft tops at BMW.
Difficulties of this nature are often associated with inaccuracies and slippage on the positioning sensor system.
The design takes the form of a double-row ball bearing with a single hard plastic overmoulding, incorporating a soft rolling surface on the outer diameter.
This provides excellent sensor track adhesion, and so ensures consistent positioning.
At the same time, it prevents slippage and deformation.
The hard plastic bearing hub design contributes to reduced vibration and noise levels, and the soft thermoplastic outer minimises wear.
Performance features are maintained irrespective of elevator speed and length of travel.
