FAQ

Question? What is the correct tightening procedure for a KM07 lock nut?

Answer

A KM07 lock nut should be tightened using a hook spanner (also known as a C-spanner) or an impact spanner that fits the four peripheral slots. Tighten to the manufacturer's recommended torque for the specific bearing and application to ensure proper preload and secure locking. It is often used with a locking washer (MB series) where a tab is bent into one of the slots to prevent loosening.

Question? Is the GISS KM07 interchangeable with an SKF KM 7?

Answer

Yes, the KM series of lock nuts follows international standards (ISO 2982-2). As long as the designation is KM07 (or KM 7), the critical dimensions such as the M35x1.5 thread, outside diameter, and width are standardized. Therefore, a GISS KM07 is fully interchangeable with an SKF KM 7 or equivalent from other reputable manufacturers.

Question? What material is the KM07 lock nut typically made from?

Answer

Standard KM-series lock nuts are typically manufactured from high-quality steel, often a grade like S45C or equivalent. This provides the necessary strength and durability to secure bearings under operational loads and vibrations. The surface may have a black oxide or phosphate finish for corrosion resistance.
