Practical benefits

Prevents accidental loosening: By bending a washer tab into the nut slot, you lock your assembly firmly against heavy vibration.
Quick and simple installation: You align the inner tab directly into the shaft keyway to achieve an effortless and accurate fit.
Durable steel construction: Built from solid steel, it provides dependable structural rigidity so you can maintain stable shaft assemblies over time.

In a nutshell

The right choise for

With the Skf mb 13 lock washer, you securely lock a km 13 lock nut onto a shaft or adapter sleeve. The inner tab engages cleanly with the shaft keyway, allowing you to bend an outer tab directly into the nut slot for a positive mechanical lock. This prevents bearing assemblies from vibrating loose during operation and eliminates unintended axial play without damaging the shaft threads. Built from durable steel with a 65 mm inside diameter and a 92 mm outside diameter, it helps you perform machinery overhauls and maintenance with complete confidence.
