SIBCO is an SKF Group brand and the offerings under SIBCO cover a wide range of industrial applications, which deliver the same superior quality and performance that you associate with the SKF brand. The product assortment under the SIBCO brand consists of housings, seals, sleeves, locating rings, nuts, and washers. Locknuts are used to locate bearings onto a shaft. Additionally, they can be used to mount bearings with a tapered bore onto tapered shaft seats and adapter sleeves and to dismount bearings from withdrawal sleeves. Locknuts are also frequently used to secure gears, belt pulleys, and other machine components.

Lock nuts have to be secured to prevent unintentional loosening by:

a locking device that engages a keyway in the shaft or key slot in the adapter sleeve, or a locking mechanism integrated in the nut.
SKF lock nuts provide a variety of ways to secure the nut onto a shaft. The lock nuts listed here constitute the basic SKF assortment. Locknuts with other locking methods can be supplied on request. For additional information, contact SKF.
