Frequently asked questions
Common questions about BELDEN from 3G Electric.
What are the key specifications of Belden heavy duty universal joints for keyed shafts?
Belden heavy duty universal joints for keyed shafts, such as the UJ-HD1500x750K, feature a 1500 series design with a 3/4 inch bore diameter and 4 1/4 inch overall length. They are constructed from alloy steel and are available with AS9100D certification, AS9102 FAIR, DFARS compliance, lot traceability, part serialization, REACH compliance, and RoHS2. These joints are designed for high torque transmission in applications with angular misalignment. The keyed shaft connection provides positive engagement and prevents slippage under load. They are suitable for heavy-duty industrial applications where reliability and traceability are required.
What is the difference between Belden high-speed universal joints for round shafts and heavy duty models?
Belden high-speed universal joints for round shafts, such as the NB-UJ750X3/8, are designed for applications requiring higher rotational speeds and lower torque. They feature a round bore and are often supplied assembled. Heavy duty models, like the UJ-HD1500x750K, have a keyed bore for higher torque capacity and are built for rugged industrial use. High-speed models are available in series 750, 1250, 1500, and 2000, with bore diameters from 3/8 to 1 inch. Heavy duty models typically have larger bore sizes and are constructed from alloy steel for increased strength. Selection depends on the specific torque, speed, and misalignment requirements of the application.
Are Belden stainless steel universal joints suitable for corrosive environments?
Belden stainless steel universal joints, such as the SS-NBUJ1250X5/8 and SS-NBUJ1500X3/4, are constructed from stainless steel, which provides resistance to corrosion and oxidation. They are suitable for applications in washdown environments, outdoor installations, and exposure to moisture or mild chemicals. However, the specific grade of stainless steel is not detailed in the provided specifications, so for highly corrosive environments, additional protection or a different material may be required. These joints maintain the same dimensional and performance characteristics as their alloy steel counterparts, with bore diameters from 5/8 to 1 inch and series 1250, 1500, and 2000. They are often used in food processing, pharmaceutical, and marine applications.
What series of Belden universal joints are available and how do they differ?
Belden universal joints are available in series 750, 1250, 1500, and 2000. The series number generally correlates with the size and torque capacity of the joint. Series 750 is the smallest, with bore diameters starting at 3/8 inch and overall lengths around 2 11/16 inches. Series 1250 has a 5/8 inch bore and 3 3/4 inch overall length. Series 1500 has a 3/4 inch bore and 4 1/4 inch overall length. Series 2000 is the largest, with a 1 inch bore and 5 1/2 inch overall length. Higher series numbers indicate larger physical size and higher torque capacity. All series are available in alloy steel or stainless steel, and in round or keyed bore configurations. The series designation helps in selecting the appropriate joint for a given shaft size and load requirement.
What certifications and compliance standards apply to Belden universal joints?
Some Belden universal joints, particularly the heavy duty models, are manufactured to AS9100D, which is an aerospace quality management standard. They may also come with AS9102 First Article Inspection Reports (FAIR), DFARS compliance, lot traceability, and part serialization. Additionally, they are REACH and RoHS2 compliant, restricting hazardous substances. These certifications and compliances are important for aerospace, defense, and other regulated industries. Not all models carry the same certifications; for specific compliance requirements, consult the individual product datasheet or contact 3G Electric for verification. The stainless steel models may have different compliance status, so it is essential to confirm before ordering.
How do I select the correct Belden universal joint for my application?
To select the correct Belden universal joint, consider the shaft diameter (bore size), the torque and speed requirements, the amount of angular misalignment, and the environmental conditions. Determine whether the shafts are keyed or round, and choose the appropriate series based on the torque capacity. For high-speed applications, select a high-speed model; for heavy-duty, choose a heavy duty model. Material selection depends on corrosion resistance needs: alloy steel for strength, stainless steel for corrosion resistance. Also verify the overall length and connection type. 3G Electric provides datasheets and can assist with selection. It is recommended to review the application's maximum torque, speed, and misalignment angle to ensure the joint operates within its ratings.
