Product Overview: The KM 18 Lock Nut
The KM 18 is a high-quality metric Lock Nut, an essential component for securely mounting bearings on shafts. Designed with a standard M90x2 thread, this lock nut is used to axially locate bearings and other components, preventing loosening caused by vibration or operational forces. It is specifically engineered to be used in conjunction with an MB 18 lock washer, which engages with a keyway on the shaft and one of the nut's outer slots to provide a simple and reliable locking mechanism.
As a key part of our Bearing Accessories range, the KM 18 is manufactured to precise standards to ensure a perfect fit and dependable performance. It is commonly used with adapter sleeves, such as the H 318, to mount bearings with a tapered bore onto a cylindrical shaft. This makes it a vital part for a wide variety of industrial and mechanical assemblies.
Features of the KM 18 Lock Nut
- Precision Machining: Features a precisely manufactured M90x2 metric thread for smooth installation and accurate adjustment.
- Secure Locking System: Designed with four slots on its outer circumference to engage with the tab of a corresponding lock washer, ensuring a firm hold.
- Durable Construction: Made from high-strength steel to withstand tightening forces and resist wear and deformation over time.
- Reusable Design: Can be dismounted and reused multiple times without loss of performance, making maintenance and adjustments cost-effective.
- Standardized Dimensions: Conforms to international standards, ensuring interchangeability and compatibility with other standard components.
- Corrosion Resistance: Typically treated with a protective finish to resist rust and corrosion in various operating environments.
Applications of KM 18 Lock Nuts
