Adapter Sleeve & Lock Nut

Adapter Sleeve

Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seat as they can be used on plain shafts or stepped shafts.

They are easy to install and require no additional location on the shaft. When used on plain shafts, the bearing can be located at any position on the shaft. When used on stepped shafts together with an L-shaped spacer ring, the bearing can be accurately positioned axially, thereby facilitating bearing mounting and dismounting.

Lock Nut

Lock nuts 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. Lock nuts 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.

MEGHA lock nuts provide a variety of ways to secure the nut onto a shaft. The lock nuts listed here constitute the basic MEGHA assortment.
