The NTN AL series lock washer is used with slotted nuts to secure bearings and other shaft-mounted components. It features an outer tab and an inner tab that bends over the nut to prevent loosening from vibration. MR Industrial Accessories supplies this series to customers in the United States and Latin America.

The AL designation starts with the letters AL followed by a number that represents the nominal diameter of the shaft or thread. For instance, AL44, AL52, and AL60 match lock nuts with the same size code; the number is not the shaft diameter. The numeric suffix lets you select the correct washer for your shaft size and nut.

These washers are found in many industrial settings, including conveyor systems, mills, pumps, fans, machine tools, and power transmission equipment. They are common in bearing mounting on gearbox shafts, electric motors, and agricultural machinery where secure fixing is essential.

When choosing a lock washer, consider the shaft diameter and the lock nut type. The inner tab must fit the shaft groove, and the outer tab must bend over a nut notch. During installation, ensure the washer seats properly and bend the tab without damaging the part. Lubricating the assembly also helps with durability.

NTN AL series lock washers can be interchanged with other brands that follow the same dimensional standard. If you have a code from another brand or an unidentified part, MR Industrial Accessories can quote it and suggest a compatible alternative. Ask us about the exact size you need.
