A lock washer from the NTN ALL series works alongside a slotted nut to hold bearings and similar components in position along a shaft. An inner tab seats in the shaft groove while an outer tab folds against the nut, which keeps it from backing off under vibration. MR Industrial Accessories LLC quotes this series for maintenance and purchasing teams in the United States and Latin America.
Reading the code is straightforward: ALL comes first, followed by two or three digits that point to the shaft diameter or the nut size it pairs with. ALL44, ALL48, ALL56 and ALL60 are examples in ascending order. This is a locking element, not a bearing, and it sits between the nut and the component being secured. The most reliable way to order is to send the exact code printed on the drawing or on the part being replaced.
Typical installations include gearboxes, pumps, reducers, transmission assemblies and general machinery where a bearing or threaded component has to stay put. Plant maintenance crews, repair shops and equipment builders all use them. The part is small, but when it fails the nut works loose and the bearing loses its fit on the shaft.
Selection comes down to matching the nut it will serve. Diameter and pitch both matter, since the inner tab has to enter the shaft groove and the outer tab has to reach over one face of the nut. Material and heat treatment should suit the tightening torque and the vibration level of the application. At assembly, seat the nut correctly and bend the tab into place without forcing it.
Nomenclature for lock washers varies from one manufacturer to another, and parts are not always interchangeable across brands. If you are working from another brand's code or from an unmarked part, send a photo or the main measurements and the team will identify a suitable equivalent.
To get a quote on an NTN ALL series lock washer, send the full code through WhatsApp or email, for example ALL44, ALL48 or ALL56, or simply the nut and shaft measurements. The team replies promptly and can also help you choose if you are unsure which size fits.

Frequently asked questions
- What does an ALL series lock washer do?
- It pairs with a slotted nut to secure bearings and other components on a shaft. The inner tab locates in the shaft groove and the outer tab bends over the nut, preventing it from loosening.
- Which size do I need?
- You need the nut diameter and pitch, plus the shaft diameter, so the inner tab matches the groove. If you still have the old code, send it as it appears; if not, send the measurements and the team will help identify it.
- Can you supply outside my area?
- MR Industrial Accessories LLC serves customers throughout the United States and in several Latin American countries. Send the code by WhatsApp or email and the team will reply promptly with a quote.
