Product Overview: The KM 34 Lock Nut
The KM 34 is a high-quality metric Lock Nut, also known as a shaft nut or bearing nut, designed for securing bearings and other components onto a shaft. With a standard metric thread of M170x3, it is a crucial part of our Bearing Accessories range. These nuts are used to axially locate bearings, prevent loosening due to vibration or operational forces, and facilitate the precise mounting of bearings on both plain shafts and adapter sleeves.
Manufactured to strict industry standards, the KM 34 ensures a secure and reliable fit. It features four equally spaced slots on its circumference that engage with the inner tab of a corresponding MB 34 lock washer to lock the nut in place after tightening. This simple yet effective mechanism prevents the nut from backing off during operation, significantly enhancing the safety and reliability of the entire assembly. For robust and dependable bearing mounting solutions, the KM 34 is an industry-standard choice.
Key Features of the KM 34 Lock Nut
