Abstract

A bearing system comprises a support member and a rotational element having a generally cylindrical bearing surface, and a plurality of detents defined upon and extending in from the cylindrical bearing surface, and may include means for rotating the rotational element in relation to the support member. The bearing system also comprises at least three bearing assemblies, each comprising a cam member rotatably mounted to the support member. Each of the cam members comprises a cam surface having a profile that contacts the cylindrical bearing surface and rotates away from a home position when the cam is rotatably positioned to meet one of the bearing regions, and does not contact the cylindrical bearing surface when the cam is rotatably positioned to meet one of the detent regions. Each of the cam members are rotationally biased toward their home position.
