UNS 3.340-12 Left-Hand Thread Replaces Standard PRL-17, Whittet-Higgins NL-17 Threaded Shaft & Bearing Locknut Not Self-Locking

Whittet-Higgins NL-17 Threaded Shaft & Bearing Locknut, UNS 3.340-12 Left-Hand Thread, Not Self-Locking, Replaces Standard PRL-17,: Whittet-Higgins Company: Industrial & Scientific. Whittet-Higgins NL-17 Threaded Shaft & Bearing Locknut, UNS 3.340-12 Left-Hand Thread, Not Self-Locking, Replaces Standard PRL-17,: Whittet-Higgins Company: Industrial & Scientific. Basic Locknut – Left Handed。Whittet-Higgins shaft locknuts for bearing & power transmission assemblies function by mounting a keyed and tanged shaft lockwasher between the bearing or other power transmission component and the corresponding locknut. The locknut is mounted and torqued up the shaft forcing the lockwasher forward until the desired preload and assembly seating is established. The locknut is rotationally adjusted to have the nearest slot and tang aligned; then the tang of the lockwasher is bent into the slot of the locknut which prevents the power transmission components from disassembling during operation.。Benefits:。--Used in assemblies where motion would tend to loosen a conventional right-hand thread。--Provides four (4) spanner slots which doubles the number locking positions for improved setting of assembly。--Accurately preloads bearings & other mechanical components。--Retains assemblies from loosening from larger forces of vibration, shock-loading, and torque 。--Most cost effect bearing retaining line offered。--No special tools required for installation of locknut and lockwasher。--Effective on both soft and hardened shafts。--Meets and exceeds specifications of ANSI/ABMA 8.2-1991。--Manufactured in USA。--RoHS Compliant。Applications:。--High precision assemblies。--Gear box assemblies。--Packaging equipment。--Pump manufacturers。--Numerous other machinery and equipment applications。Specifications:。--Max. Outside Diameter: 4.406。--Max. Thickness: 0.635。--Thread Size: 3.340-12。--Max. Operating Temperature: 350°F。--Material: Carbon Steel。Engineering support and CAD drawing models available at manufacturer’s website.。 。 。 。
