Product Overview: The KM 20 Lock Nut
The KM 20 lock nut is a crucial precision fastening component designed to securely locate bearings onto a shaft, either directly on a tapered shaft journal or, more commonly, on an adapter sleeve. This robust nut ensures that the bearing assembly maintains its axial position, preventing movement and ensuring stable operation of machinery. With an approximate bore diameter of 100mm, an outer diameter of 130mm, and a thickness of 20mm, the KM 20 provides a reliable and strong locking mechanism for various industrial applications.
As a key component in bearing arrangements, the KM 20 lock nut is typically used in conjunction with a corresponding MB 20 lock washer, where the washer's tab fits into a keyway on the shaft or adapter sleeve, and one of its outer tabs is bent into a slot on the lock nut, thereby preventing the nut from loosening under vibration or dynamic loads. Our KM 20 lock nuts are manufactured to industry standards, guaranteeing a secure fit and long-lasting performance in demanding industrial environments.
Key Features of the KM 20 Lock Nut
- Secure Axial Locking: Designed to firmly hold bearings in place on shafts or adapter sleeves, preventing unwanted axial movement.
- Robust Construction: Manufactured from high-quality steel for exceptional strength and durability, ensuring reliable performance under load.
- Precision Threading: Features accurately machined threads for smooth and secure engagement with the shaft or adapter sleeve.
- Vibration Resistance: When paired with a lock washer (such as MB 20), it provides excellent resistance to loosening from vibration and shock.
- Standardized Dimensions: Conforms to industry-standard specifications, allowing for interchangeability and ease of integration.
- Versatile Application: Suitable for a wide range of machinery and equipment requiring precise bearing retention.
