Merits of the Flanged Pulley          

          Flanged Pulleys are Guide Pulleys or sheaves consisted of a precision grooved ceramic ring, clamped between two flanges with provision to secure bearing(s) at the center to impart rotational motion the wire in a parabolic path, in conformity with the change in the wire's direction of movement. See exploded view, right. They feature:

              Light weight, low starting torque

              Superior surface finish, usually diamond-lapped         A flanged pulley, disassembled

              Interchangeability of flanges

Nylon Flanged Pulleys

          Nylon flanged pulleys are used extensively in coil winding, tension control, pay off and take up devices.  When fitted with resin bearings and nylon assembly screws, nylon flanged pulleys are equally versatile in guiding wires submerged in room temperature water or mild acid baths. 

Aluminum Flanged Pulleys

          Aluminum flanged pulleys feature precision machined components, assuring concentric rotation for applications where wire tension monitoring is critical. They are capable of guiding wire at elevated temperatures but are not suitable for submerged operations.

Metric Bearings on Inventory

          Eighteen (18) COSMOS Flanged Wire Guide Pulleys are depicted in dimensional drawings in the ensuing pages.  All units are in mm.  Bearing numbers refer to default metric ball bearings currently on inventory.  Imperial (inch) ball bearings or resin bearings are available upon request.
