LR
LRE
LR & LRE locknut uses steel’s elasticity characteristics to securely fix the locknut in the radial direction.
This type of nut is thinner and suited to more narrow applications. The design is very simple and easy to lock. This type of nut is not suitable for high precision requirements as it is more difficult to assure the perpendicularity of the nut at this size.
⚠️ Not applicable for installations where radial set screws cannot be tightened due to space constraints.
