What is an Adapter Sleeve?
An Adapter Sleeve is a cylindrical component used to mount bearings with tapered bores onto cylindrical shafts. It helps in proper positioning of the bearing and simplifies installation and removal.
Key Functions:
- Allows mounting of tapered bore bearings on straight shafts
- Compensates for minor variations in shaft size
- Enables quick assembly and disassembly without damaging bearings
What is a Nut?
In bearing assemblies, a Nut (Lock Nut) works with an adapter sleeve to secure the bearing in place. It is threaded onto the sleeve to tighten and lock the bearing in position.
Key Functions:
- Holds the bearing securely on the sleeve
- Prevents axial movement during operation
- Works with a washer to prevent loosening
What is a Washer?
A Washer (Lock Washer) is placed between the nut and the bearing or housing to prevent the nut from loosening due to vibration.
Key Functions:
- Locks the nut in place
- Provides stability and prevents back rotation
- Works as a safety component in high-speed applications
