Milwaukee Sliding Collar
Model Number: 45-22-5319
The Milwaukee 45-22-5319 is a genuine OEM Sliding Collar for Milwaukee SDS-Max rotary and demolition hammers. It is the collar at the front of the SDS-Max tool holder, part of the bit-retention mechanism the operator pulls back to insert or release an SDS-Max bit. The SDS-Max system lets the bit slide back and forth axially so the hammer mechanism can drive it, while locking the bit against rotation and against pulling out of the tool, and the sliding collar is the outer control the operator manipulates to load and unload bits. It works together with the locking sleeve directly behind it and the spring assembly that returns it to the locked position. Because the collar is handled on every bit change, sits at the front of the tool where it takes impact and concrete dust, and is one of the most-used parts on a working hammer, it is a common wear and impact item. When it is cracked, worn, or no longer returns under spring pressure, bit changes become difficult, bits may fail to lock in, or bits may not insert or release cleanly. Replacing it with the correct genuine Milwaukee OEM collar restores the fit and travel the tool holder depends on, which is both a performance and a safety matter, since a bit that is not positively retained is a hazard.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before placing your order, since running production changes can alter part compatibility within the same catalog number. This sliding collar is documented at Figure 7 on the SDS-Max tool holder of several Milwaukee hammers, including the 5317-20 Demolition Hammer, the 2717-20 Hammer Drill, the 5546-21, and the 5518-21, appearing on bulletins 54-24-2760, 54-24-2795, and 55-24-1625, and it is referenced on additional SDS-Max hammers, so confirm your catalog and serial number before ordering. On the diagram it sits directly ahead of the Locking Sleeve, ordered separately as 45-22-5321 at Figure 8, and behind that are the washer, front and rear spring retainers, and spring that provide the return action. Those spring-assembly parts carry slightly different part numbers between models, so verify the exact numbers on your tool's diagram, and if the collar is worn it is worth inspecting the locking sleeve and spring at the same time since they wear together. Milwaukee specifies grease for the tool holder at reassembly, sold separately.
