There is provided a bend-test device for wire harnesses, capable of handling a plurality of samples at the same time. A sealing member for a bearing may have a resilient axial seal extending from an outer diameter of the sealing member and a plurality of resilient sealing lips extending radially from an inner diameter of the sealing member. The pixel counts are obtained by comparators that receive the adjusted signals at one input and the desired comparator signal levels at the other input. Each wall has a length V from the base and a thickness X.
