Product Overview: The KM 27 Lock Nut
The KM 27 is a precision-engineered lock nut, an essential component in our range of Bearing Accessories. Designed with a metric thread of M135x2, this lock nut is primarily used to locate and secure bearings and other machine components onto a 135mm shaft. Its design ensures that bearings are firmly held in place, preventing axial movement and maintaining the correct operational settings within a mechanical assembly. For a secure and reliable fastening, it is designed to be used in conjunction with an MB 27 lock washer.
As a key supplier of industrial parts, we provide high-quality Lock Nuts that meet industry standards for performance and durability. The KM 27 features four equally spaced slots on its outer circumference, allowing for easy tightening and loosening using a hook or impact spanner. This simple yet effective design makes it a popular choice for mounting bearings on both plain shafts and adapter sleeves.
Key Features of the KM 27 Lock Nut
- Precise Fit: Manufactured with a standard M135x2 thread for compatibility with 135mm shafts.
- Secure Locking: When paired with an MB 27 lock washer, it provides a reliable locking mechanism that prevents loosening from vibration or operational loads.
- Durable Construction: Made from high-strength steel to withstand significant tightening torque and ensure long service life.
- Easy Installation: Features four slots for standard hook or impact spanners, simplifying the mounting and dismounting process.
- Reusable Design: Can be reused multiple times in normal operating conditions without losing its locking effectiveness.
- Versatile Application: Suitable for securing a wide variety of bearings, gears, and pulleys onto a shaft.
