Under the current administration, we have been in business since 1988 however under different names. We began manufacturing turbine components for the gas turbine industry. In 1992, we generalized into basic machine shop work. In 1997, the three companies were merged into C-Flex Bearing Co., Inc. with the focus on our one product line, the frictionless bearing or pivot.

Current Capacity: 6200 square feet. 6000 square feet of manufacturing space with expansion property available.

C-Flex Suppliers:

We extend every effort to keep key processes in house in order to maintain the tightest control over quality and timeliness. With our increase in sales and in order to maintain stock levels on standard items, we are in constant review of production methods so as to best meet quality, quantity, and scheduling demands of our customers.

Quality and Testing:

Quality at C-Flex begins with the receipt of materials. All employees assume in-process responsibility for quality checks. Final quality verification prior to placement of components to inventory and shipment to the customer is under the control of our chief quality engineer.

C-FLEX realizes the significance of sustainability and our products are produced without harmful oils, materials detrimental to

the environment.

PIVOT BEARINGS

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¡ã, 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 advantages of cross-flexure bearings has 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 spectometer. Here two mirrors are mounted on an assembly and laser beams are scanned across 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¡ªeliminating 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).

Other applications include those requiring accuracy without backlash, friction and wear such as gimbals or within gauge sensors where position must be accurately measured or outside forces sensed. Workhorse applications requiring the support of heavy loads for years of continuous service including mechanisms such as vibrating hoppers. Lever actuators and tensioners can also benefit from the use of these bearings. Optical/magnetic read/write heads also gain from the constant predictable spring rate-immune to the problems of starting vs. moving torque.

Free from backlash, friction and wear, the C-Flex bearing could provide the ultimate in cost effective design, allowing for easy assembly and indefinite life expectancies with undiminished accuracy. Selection of the correct bearing for the application loads expected should result in exceptional long life, even within the most arduous environment.

Custom designs for heavy loads (>1600 lbs.), special materials (e.g., Hast X, Titanium, BeCu) or high volume/low cost can be provided.
