How to choose Locking washers

Points to check when selecting, with the values for this product (Inch-Series W Lock Washer).

  1. 1. Match the lock nut designation number

    Select the lock washer according to the designation number of the lock nut it will be used with. Each series is fixed, such as AN/AW-series nuts for metric MB and N-series nuts for inch-series W. Mixing different series will cause the tabs and notches not to align, preventing proper fixing.

  2. 2. Match the inner diameter to the shaft or sleeve diameter

    This product: Inner diameter d 0.406–8.701 in.

    The inner diameter d corresponds to the thread diameter of the applicable shaft or adapter sleeve. Confirm that the inner tab fits properly into the keyway, together with the keyway width and depth. For inch-series products, pay attention to the unit used in the dimension notation.

  3. 3. Check the outer diameter and nut notch position

    This product: Outer diameter d2 0.655–11.438 in.

    The outer diameter d2 determines whether the outer tab can be bent into the notch of the lock nut. Based on the outer diameter, also check for interference with surrounding housings and seals.

  4. 4. Account for axial space using the thickness

    This product: Thickness B 0.032–0.115 in.

    The thickness B adds to the axial dimension from the bearing to the nut. During design, confirm that the threaded section is long enough and that the plate thickness allows the tab to be bent.

  5. 5. Select material according to the operating environment

    Steel is generally used, but in environments exposed to water or chemicals, consider stainless steel to avoid seizure caused by rust and loss of strength. Also consider compatibility with the nut and shaft materials.

  6. 6. Consider clip or plate systems for large diameters

    For large-diameter nuts or locations where bending the tabs is difficult, a system using fixing clips or fixing plates fastened with bolts can be used. Confirm that all components, including bolts, washers, and wire, are available.
