C-Flex Bearing Co., Inc. is located in Frankfort, NY and manufactures the Flex Pivot (frictionless bearing) and the Lattice Coupling.
The advantages of cross-flexure bearings have been well documented in connection with the replacing of ball bearing pivots in optomechanical applications. One such application in which the C-Flex bearing has outperformed alternatives is the scanning mirror assembly of a mass spectrometer. Here two mirrors are mounted on an assembly and laser beams are scanned across the samples to be analyzed. The lubrication free, frictionless movement of the C-Flex bearings is ideal in applications such as this, where the outgassing from bearing lubricants could contaminate the optics, and bearing wear due to continuous limited rotation would eventually result in movement errors.
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).
The C-Flex Lattice Coupling is an economical answer to misalignment needs. It is offered in metal and SUPERPLASTIC materials. Key features of the C-Flex coupling are:
