Product Overview: The KM 31 Lock Nut
The KM 31 is a precision-engineered metric Lock Nut, an essential component in our range of Bearing Accessories. Designed with a standard M155x3 thread, this lock nut is primarily used to securely locate bearings and other mechanical components onto a shaft, preventing axial movement and ensuring operational stability. It works in conjunction with a corresponding MB 31 lock washer to create a reliable locking mechanism that resists loosening caused by vibration or rotational forces.
As a key supplier of industrial parts, we provide high-quality KM 31 lock nuts that meet strict industry standards for dimensional accuracy and material strength. Their simple yet effective design allows for easy installation and precise adjustment of bearing clearance, making them a fundamental part of countless machinery assemblies across various sectors. For a complete mounting solution, pair this nut with our adapter sleeves and lock washers.
Key Features of the KM 31 Lock Nut
- Precision Machined Threads: Features a standard M155x3 thread for a secure and accurate fit on shafts or adapter sleeves.
- Multiple Locking Positions: Designed with four equally spaced slots on its outer circumference to engage with the inner tab of an MB 31 lock washer.
- Durable Steel Construction: Manufactured from high-strength steel to withstand high tightening torques and ensure long-term reliability.
- Easy Installation and Removal: Can be easily tightened or loosened using a standard hook or impact spanner.
- Positive Locking: When used with a lock washer, it provides a secure locking system that prevents the nut from backing off during operation.
- Standardized Dimensions: Conforms to ISO 2982-2 standards, ensuring interchangeability with other standard components.
