SKF AN 34 Adapter Sleeve Lock Nut M170x3 - High Precision Shaft Locking
The SKF AN 34 Lock Nut is a specialized, high-precision retaining device critical for securing bearings, particularly those mounted on adapter sleeves (H Series) or directly onto tapered shafts. Manufactured to stringent SKF quality standards, this lock nut provides the exact axial force required to seat the bearing correctly, ensuring optimal internal clearance and alignment. Its robust construction utilizes high-strength material capable of withstanding significant operational stress and vibration, making it essential for heavy industrial machinery, gearboxes, and large pumping systems where reliable bearing retention is paramount. The AN 34 is designed specifically for M170x3 threads and requires standard tools (hook spanner) for accurate tightening and removal, streamlining maintenance procedures.
Employing the correct lock nut, such as the AN 34, is vital for maximizing the service life of the entire bearing arrangement and preventing costly premature failures associated with movement or insufficient mounting force. This component works synergistically with corresponding locking washers (e.g., MB 34) to provide a failsafe securing method that resists loosening even under dynamic loads. We ensure that this non-standard accessory meets all relevant ISO standards for dimensional accuracy and material composition, guaranteeing a perfect fit with existing SKF components. Invest in genuine SKF accessories to maintain the integrity, safety, and operational efficiency of your mission-critical rotating equipment.
