Locking Assemblies RfN 7012 Stainless Steel
Key Features of Locking Assemblies RfN 7012 Stainless Steel
Locking Assemblies RfN 7012 Stainless Steel are designed to offer the same design and functionality as the traditional 7012 device but are made from stainless steel. This makes them ideal for applications requiring rust-free installations. Due to the properties of stainless steel, the torque capacity is slightly reduced compared to the standard 7012 device. It also known as "khớp khóa trục RfN 7012 SST".
These assemblies ensure reliable performance in various conditions while maintaining the benefits of stainless steel, such as corrosion resistance and longevity. They are suitable for applications where maintaining a clean and rust-free environment is crucial, providing a durable and efficient solution.
The RfN 7012 SST comes in 30 different sizes, offering a versatile range for various applications.
- Inner Diameter (d): Ranges from 19 to 150 mm, accommodating various shaft sizes.
- Outer Diameter (D): Spans from 47 to 200 mm, ensuring adaptability to different hub sizes.
- Overall Length (L): Varies between 27.5 and 52 mm, allowing flexibility in installation.
- Torque (T): Can handle values between 252 and 24,046 Nm, ensuring robust and reliable performance in demanding conditions.
These specifications make the RfN 7012 SST suitable for a wide spectrum of industrial applications, offering both efficiency and reliability in operation.
