SKF KM 40 Lock Nut And Locking Device Bearing Accessories

• Lock nut for locating bearing on shaft
• Uses locking washer (sold separately) for accurate placement
• Steel nut for strength and durability
• Right hand threads
• Metric unit measurement for industry consistency

This steel lock nut has right hand threads, uses a locking washer, and is suitable for locating a bearing and other components onto a shaft, as well as for facilitating mounting bearings on tapered journals and dismounting bearings from withdrawal sleeves. The washer (sold separately) engages a keyway in the shaft and locks the nut in position if one of the tabs is bent over into one of the slots around the circumference of the nut. Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers. SKF manufactures bearings, seals, and lubrication systems for automotive, energy, and other industrial applications. The company, founded in 1907 and headquartered in Gothenburg, Sweden, meets International Organization for Standardization (ISO) standards TS 16949 and 9001.
