AN 18 Adapter Nut – M90x2 Precision Locknut for Tapered Bearing Shafts | High-Strength Industrial Locking Component
The AN 18 Adapter Nut is a high-precision locking component critical for securely mounting bearings with a tapered bore onto cylindrical or tapered shaft seats, or adapter sleeves. Manufactured from robust, high-tensile steel, this nut features a precise M 90x2 thread specification, ensuring exceptional axial load transmission and reliable positioning. Its design accommodates standard industrial installation methods and is dimensionally compatible with common lubrication systems and housing assemblies. The standardized dimensions and material composition guarantee performance reliability even in environments subjected to high temperature variations or corrosive elements.
By facilitating precise axial location and secure locking, the AN 18 significantly reduces the risk of bearing creep, slippage, or premature loosening under heavy industrial loads and severe vibrational conditions. It is specifically engineered to be paired with the corresponding KM 18 lock washer, which provides an effective anti-rotation feature necessary for maintaining optimal bearing setting and clearance throughout the operational lifespan. Utilizing the AN 18 ensures minimized maintenance downtime, prolonged bearing service life, and maximized operational efficiency across demanding applications such as heavy machinery, gearboxes, and conveyer systems.
