Ringfeder's Two-Piece Shrink Discs® Allow for Better Centering and Concentricity



Westwood, NJ- Ringfeder's Two-Piece Shrink Discs® provide shaft/hub connection solutions for a variety of high-speed applications, especially when external clamping is necessary. The long, shallow taper allows the Two-Piece Shrink Discs® to generate higher torques than traditional three piece units. Its better-balanced design permits higher speed connections, without special balancing. Applications include wind turbine connections on speed increaser gearboxes, hollow shaft connections in mining gearboxes and any other type of connection where a high-speed coupling is needed.

Installation is also simplified. The design of the Two-Piece Shrink Disc® provides the installer with a visual aid to see if the Shrink Disc® is properly installed. When the fasteners are properly torqued, the inner ring face will be flush with the outer ring face when completely tight. A torque wrench is recommended to properly tighten the screws.

The high alloy steel Two-Piece Shrink Discs® can always be used in place of traditional three-piece Shrink Discs®. The Two-Piece Shrink Discs® are available in both standard and metric sizes, from >" to 20" and 19mm to 500mm with torque ranges from 136 lb-ft to 860,000 lb-ft. Low Inertia Series Shrink Discs® and Heavy-Duty Shrink Discs® for smaller shafts are available upon request.
