Ringfeder Shrink Disc Stainless Steel 155 mm, 6050 Nm Torque, Length 45.8 mm, Series RfN 4061, Model 4061 - 85x155

The Ringfeder 4061-85x155 shrink disc is an advanced mechanical power transmission component engineered for secure and backlash-free shaft-to-hub connections in demanding industrial environments. With a torque rating of 6050 Nm, this shrink disc provides reliable performance for applications requiring precise torque transmission and high stability.

This model features a 155 mm shaft compatibility and a total length of 45.8 mm, making it suitable for large-scale drives and rotating equipment in engineering, mining, materials processing, and automated production lines. The use of stainless steel in its construction offers outstanding resistance to corrosion, mechanical wear, and high-stress cycles, supporting long-term operational integrity in diverse environments.

The shrink disc design utilizes high alloy forged rings, making it practically indestructible while also simplifying installation and removal procedures. Replacing previous smaller designs, such as the 4071 series, it benefits from an improved architecture while retaining compatibility across shaft sizes from 14 mm to 195 mm within the RfN 4061 series. The unit guarantees secure, backlash-free operation and can be used in power transmission assemblies, conveyors, heavy-duty machine tools, and large rotating assemblies.

Compliance with RoHS regulations ensures safe material selection for industrial users, while the product’s German origin attests to its manufacturing quality and reliability. The Ringfeder 4061-85x155 shrink disc is a preferred solution for machine builders and industrial designers aiming to maintain secure coupling under significant torque loads, while providing simplified maintenance and extended service life.

Typical applications include heavy machinery, conveyor drives, gearboxes, blower assemblies, and precision rotary equipment. The stainless construction means the shrink disc is suitable for use in aggressive environments, including outdoor setups and corrosive processing plants.
