🔧 Purpose & Function
The H2328 adapter sleeve is used to mount tapered bore spherical roller bearings (e.g., 23228K or 22228K) onto cylindrical shafts. It simplifies installation and removal, especially in applications where disassembling the shaft or bearing seat is difficult or costly.
This sleeve expands against the shaft and the tapered bore of the bearing when the lock nut is tightened. The lock washer keeps the nut securely in place, ensuring a firm hold and vibration resistance during operation.
