FLEX PIVOT: Frictionless Bearings or Flex Pivot Bearing utilizes internal flat crossed springs, capsuled in a cylindrical housing to provide precise rotation with low hysteresis and no frictional losses. The C-Flex bearing will offer indefinite life when used within its rated load and rotational values. It is frictionless, self centering, backlash free, simple to install, uses NO lubrication. LATTICE COUPLING and SERVO COUPLING: C-Flex flexible couplings are available in English, Metric, Stainless, and Super Plastic variations. C-Flex offers a revolutionary design which combines the best characteristics of leading bellows, disc, and beam couplings all in a single integrated component. The C-Flex coupling is used for fastening, joining, and assembly, HVAC, power transmission, with ZERO backlash, low cost, large torque capacity and high torsional stiffness.
