Product Overview: The KM 23 Lock Nut
The KM 23 is a precision-engineered metric lock nut, an essential component in our range of Bearing Accessories. Designed with a nominal thread diameter of 115mm, an outer diameter of 150mm, and a thickness of 22mm, this Lock Nut is primarily used to securely locate bearings and other components onto a shaft, preventing any axial movement. It is designed to be used in conjunction with a corresponding lock washer, such as an MB 23, which engages with a keyway on the shaft and a slot on the nut to provide a simple yet highly effective locking mechanism.
As a key supplier of industrial parts, we provide KM 23 lock nuts manufactured to industry standards. They are critical for mounting bearings with a tapered bore onto a cylindrical seat using an adapter sleeve, like the H 2324. This assembly method simplifies installation and removal while ensuring a tight, reliable fit. Whether for new machinery or maintenance and repair, the KM 23 offers a dependable solution for securing rotating components in a wide variety of industrial settings.
Features of the KM 23 Lock Nut
- Precision Machining: Features accurately machined metric threads (M115x2) for smooth installation and proper engagement.
- Secure Locking System: Designed with four equally spaced slots on its circumference to engage with the inner tab of a lock washer, preventing loosening from vibration or rotation.
- Simplified Mounting: Allows for the precise axial positioning and securing of bearings on adapter sleeves.
- Durable Construction: Manufactured from high-strength steel to withstand tightening forces and provide long-term operational reliability.
- Reusable Design: Can be easily dismounted and reused multiple times without loss of performance, making it a cost-effective choice.
- Standardized Dimensions: Conforms to ISO 2982-2 standards, ensuring interchangeability and compatibility with other standard components.
