    5mm rigid flange coupling dimension 


    A flange coupling is a type of mechanical joint that is used to connect two rotating shafts in order to transmit power. Flange couplings are commonly used in industrial machinery and equipment, such as pumps, compressors, and turbines. The field of application for flange couplings is wide-ranging and includes industries such as oil and gas, power generation, water treatment, and manufacturing.

    Tips: How to install and maintain a flange coupling?


    1. Inspect the coupling: Before installation, inspect the coupling to make sure it's free of damage, and that the bore and keyway are clean and clear.
    2. Check alignment: Make sure the equipment is properly aligned before installing the flange coupling.
    3. Attach the coupling halves: Slide the coupling halves onto the shafts, making sure that the keyway is aligned with the key on the shaft.
    4. Tighten bolts: Tighten the bolts in a cross pattern to ensure even pressure on the flanges. Use a torque wrench to tighten the bolts to the manufacturer's recommended torque.
    5. Check runout: Check the coupling for runout by using a dial indicator. If the runout is greater than the manufacturer's specifications, realign the equipment and recheck.


    1. Regular inspection: Inspect the coupling regularly for signs of wear, cracks, or other damage. Replace any damaged parts immediately.
    2. Lubrication: Lubricate the coupling regularly using the recommended lubricant. Make sure to apply the lubricant evenly to all surfaces of the coupling.
    3. Check bolt tightness: Check the bolt tightness regularly and retighten as necessary to ensure even pressure on the flanges.
    4. Monitor alignment: Monitor the alignment of the equipment and coupling regularly. If there is any misalignment, correct it as soon as possible to prevent damage to the coupling and equipment.
    5. Replace worn parts: Replace any worn parts as soon as possible to prevent further damage to the coupling and equipment.
