Falk Wrapflex Elastomeric Couplings
Falk Wrapflex wrap-type elastomeric couplings from the Regal Rexnord portfolio. R10 size classes for general industrial drives with replaceable wrap elements.
Falk Wrapflex overview
Falk Wrapflex elastomeric couplings transmit torque through a wrap-type elastomer element seated in two hub halves. Wrapflex is a Falk portfolio brand within Regal Rexnord; it is not an independent supplier relationship.
R10 series concept
Wrapflex R10 designations identify size classes within the Falk catalogue (including documented 5R through 80R ranges). Selection follows manufacturer tables for torque duty, speed, bore capacity and misalignment. Confirm configuration (close-coupled or extended) against equipment layout.
Compared to Omega and Viva
Omega and Viva are split-in-half tire elastomeric families with different hub and element geometry. Wrapflex uses a distinct wrap element design. Families are not directly interchangeable as element swaps; verify application requirements before changing type. See Rexnord Omega and Rexnord Viva for related elastomeric options.
Engineering interchange note
Manufacturer engineering documentation documents that Dodge Sidewinder wrap couplings are dimensionally/directly interchangeable with Falk Wrapflex for documented size classes, subject to engineering and application conditions. This is not a universal interchange claim, guaranteed replacement or commercial authorisation statement. Send installed coupling details for engineering review.
Applications
Pumps, fans, conveyors, compressors and general industrial motor-driven equipment where a compact wrap elastomer element is specified.

Common questions
Wrapflex is marketed under the Falk brand within the Regal Rexnord coupling portfolio. Golden Bearing Company supports selection as an authorised Regal Rexnord distributor.
Wrapflex suits moderate industrial torque with elastomer damping and element replacement. For very high torque or shock load, compare Lifelign gear or Steelflex grid families.
Published catalogue documentation documents dimensional/direct interchange for certain documented size classes, subject to engineering review. This does not imply universal compatibility or automatic authorisation. Provide size class and application data for review.
