KM Locknut

KM Locknuts are precision-engineered axial locking components designed to securely position bearings and other machine elements on shafts. Used extensively in industrial and mechanical applications, KM locknuts provide reliable, adjustable axial location while resisting loosening under vibration and load changes.

These locknuts feature precisely machined metric threads and are used in combination with MB lock washers or other locking methods to prevent rotation, ensuring consistent clamping force and long-lasting performance. Ideal for mounting tapered bore bearings on adapter or withdrawal sleeves, KM Locknuts are essential for maintaining alignment and operational stability in rotating equipment.

Key features include:

Metric thread profiles for easy compatibility with standard shafts and sleeves
Precision machining for secure, accurate bearing location
Designed for use with MB lock washers for positive anti-rotation locking

Whether you’re assembling new equipment or replacing worn components, KM Locknuts deliver the secure, adjustable locking solution needed to maintain bearing performance and extend equipment life.
