The C-Flex bearing or “pivot” is a cylindrical, limited rotational bearing, with a high relative radial and axial stiffness which is available in low, medium or high torsional spring rates. It is typically available for maximum deflection angles of +/- 30 degrees, but various configurations are supplied upon request. Torsional stiffness ranges from .0003 Lb-In/degree to 7.8023 Lb-In/degree. It can be used simply as an oscillating unit or an extremely sensitive critical element.
The bearing itself consists of two stainless steel sleeves held in position by three leaf springs on two planes. There is no contact between the sleeves-eliminating friction-and the springs also provide the pivotal action which is inherently self centering and requires no lubrication or maintenance. The bearing is also available with an additional sleeve allowing for central mounting providing two pivotal arms(the double end bearing, sizes AD to JD).
Custom designs for greater angular travel(+/- 50degrees), heavy loads(>1600 Lb), special materials(eg. Hast X) or high volume/low cost can be provided.
