Product Overview: The KM 30 Lock Nut
The KM 30 is a precision-engineered metric lock nut, an essential component from our Lock Nut series, designed for securing bearings and other mechanical parts onto a shaft. With a standard M150x2 thread, an outer diameter of 185mm, and a thickness of 22mm, this lock nut provides reliable axial location, preventing loosening caused by vibration or operational loads. It is specifically designed to be used in conjunction with an MB 30 lock washer to create a secure and dependable fastening system.
As a key part of our Bearing Accessories range, the KM 30 is manufactured to strict industry standards, ensuring interchangeability and a precise fit. Its robust design is crucial for the correct mounting and performance of bearings, particularly when used with adapter sleeves on smooth or stepped shafts. Trust our components for your industrial machinery to ensure longevity and optimal performance.
Key Features of the KM 30 Lock Nut
- Precision Machined Thread: Features a standard M150x2 metric thread for a secure and accurate fit on shafts or adapter sleeves.
- Secure Locking Mechanism: Designed to work seamlessly with an MB 30 lock washer, which engages with a keyway in the shaft and one of the nut's slots to prevent rotation.
- Durable Construction: Manufactured from high-strength steel to withstand high tightening torques and operational stresses.
- Four Locking Slots: Equipped with four equally spaced slots around its circumference, allowing for fine adjustments and secure locking with a tab washer.
- Standardized Dimensions: Conforms to ISO 2982-2 standards, ensuring it can be used as a direct replacement for other standard KM 30 nuts.
- Easy Installation: Can be easily tightened or loosened using a standard hook or impact spanner, simplifying assembly and maintenance procedures.
Common Applications
- Bearing Mounting: Used to secure bearings onto adapter sleeves such as the H 2330, H 3030, or H 3130.
- Industrial Gearboxes: Essential for locating gears and bearings on transmission shafts, preventing axial play.
- Pumps and Compressors: Secures rotating assemblies, ensuring stability and reliability in high-speed applications.
- Conveyor Belt Pulleys: Used to fix pulley drums and their bearings firmly in place on the shaft.
- Agricultural Machinery: Applied in equipment like combines and tractors to secure wheel hubs and power transmission components.
- Mining and Construction Equipment: Provides robust fastening for heavy-duty applications where vibration and shock loads are common.
- Electric Motors: Used to hold the rotor and bearing assembly in the correct axial position.
Benefits of Using the KM 30 Lock Nut
- Prevents Axial Movement: Reliably secures bearings and other components against axial displacement, ensuring consistent machinery operation.
- Enhanced Safety and Reliability: The positive locking system with a lock washer significantly reduces the risk of loosening due to vibration, preventing catastrophic failures.
- Extended Bearing Life: Proper and secure mounting is critical for achieving the maximum service life of a bearing.
- Simplified Assembly: Provides a straightforward and effective method for mounting and dismounting bearings without damaging the shaft or bearing.
- Cost-Effective Solution: An economical and widely available component for achieving secure axial fastening in countless industrial applications.
- Reusability: The nut and washer can typically be reused if they are not damaged during dismounting, reducing maintenance costs.
