FAQ

What is the correct locking washer for the FAG KM17 lock nut?

The FAG KM17 is designed to be used with an MB17 lock washer. The washer's inner tab fits into a keyway on the shaft, and one of the outer tabs is then bent into a slot on the nut to secure it.

Tightening should be done using a suitable hook spanner (e.g., DIN 1810). The nut should be tightened to remove clearance, then slightly loosened before being secured to the specified torque or angle to achieve the correct bearing preload. Always consult the machine's maintenance manual for specific values.

The 'H.GP' marking typically indicates manufacturing details such as the production plant or a specific material treatment process. For standard applications, it does not affect the form, fit, or function, which are defined by the 'KM17' designation according to DIN 981.
