Product information

Main characteristics of the Locking Assemblies 7012

The original Ringfeder Locking Assemblies RfN 7012 are also known as "khớp khóa trục RfN 7012", feature double-tapered thrust rings with self-releasing tapers. They are designed to bridge relatively large fit clearances and are easy to install, adjust, or remove. However, they are not self-centering and typically require a pre-centering hub section.

- Slimmest Design: Optimized for applications where space is limited, ensuring it can be used in narrow spaces without compromising performance.

- Without Axial Displacement: Maintains the relative positions of the locking assembly, shaft, and hub during installation, providing stability and safety.

- Inner Diameter (d): 19-1,000 mm, accommodates a wide range of shaft sizes, offering flexibility for various industrial applications.

- Outer Diameter (D): 47-1,100 mm, suitable for a broad range of hub sizes, ensuring compatibility with diverse mechanical systems.

- Overall Length (L): 28-130 mm, compact yet robust design, allowing for efficient installations and reliable performance.

- Torque (T): 306-2.4 million Nm, capable of handling extremely high torque values, making it suitable for heavy-duty industrial applications.
