Shrink Disc RfN 4061 stainless steel

Corrosion-resistant series for high torques
3-piece shrink disc made of stainless steel.

The corrosion-resistant RINGFEDER RfN 4061 stainless steel shrink discs offer high torque capacity. Forged pressure rings made of alloy steel and stainless steel screws ensure ideal stress distribution and maximum corrosion resistance. Same transmission values as the RfN 4061. Adjustable pre-tensioning force.

Product features

• Standard series for high torques – This shrink disc supports high transmission values and can be adapted to design requirements by adjusting the tightening torque of the screws
• Slotted inner ring – low loss forces and minimal pressure on shaft and hub
• Maximum reliability – suitable for static, dynamic, and shock loads
• Simple component manufacturing – low demands on the functional surfaces of mating components
• Easy replacement – RINGFEDER shrink discs operate entirely without form fit
• Simple assembly – no shoulder, key, or pin required; can be installed anywhere on the shaft using standard screws and commercially available tools
• Easy disassembly – after loosening the clamping screws, the shrink disc releases itself and can be freely moved on the shaft
• Low sensitivity to contamination – extended service life, as the contact surfaces are tightly pressed together after the clamping screws are tightened, preventing dirt and moisture from reaching the functional surface
