Liftmaster SW22F, NYLON WASHER KIT
The LiftMaster SW22F Nylon Washer Kit is a genuine-style replacement part used in the LiftMaster Mega Swing / MSWDCBB commercial swing gate operator family. This washer kit is used in the Mega Swing arm assembly where nylon washers are specified to control spacing, reduce metal-to-metal wear, and support smooth arm movement. It is a small part, but it affects arm alignment and pivot feel.
Mega Swing operators use a specific arm and enclosure layout, so small pieces such as bolts, washers, plates, arm ends, and windows are not generic hardware. Correct geometry is important because the arm assembly transfers the operator force into the moving gate. If the wrong part is installed, the gate may bind, pull unevenly, damage the arm, or place extra load on the operator gearbox and motor.
This part should be matched by the original part number and the MSWDCBB parts diagram. It is especially important on older or high-cycle gate systems where worn bushings, loose bolts, bent plates, or gate hinge problems may have caused the original component to fail.

Technician Note
Nylon washers are often overlooked during arm service. Missing or worn washers can let metal parts rub, create side play, and change the way the arm tracks through the gate cycle.
Before Ordering
- Confirm the installed operator is a LiftMaster Mega Swing / MSWDCBB style unit.
- Match the exact SW part number from the parts diagram.
- Inspect the arm assembly and gate hinges for binding before replacing hardware.
- Do not substitute ordinary hardware for load-bearing arm parts unless the manufacturer documentation allows it.
- Make sure all required gate safety devices remain installed and working after service.
Important Ordering Warning
Several Mega Swing SW-prefix parts are similar in name but not interchangeable. Match the exact part number, location, and assembly before ordering.
Professional Advisory
Gate operator mechanical and electrical parts should be serviced with the operator powered down and secured against unexpected movement. If the gate is binding, moving unevenly, missing required safety devices, or showing electrical damage, have the system inspected by a qualified gate technician before replacing parts.
Product Questions and Answers
What is the LiftMaster SW22F used for?
The LiftMaster SW22F is used as the nylon washer hardware for the Mega Swing secondary arm assembly on compatible LiftMaster Mega Swing / MSWDCBB swing gate operator assemblies.
Which operator is SW22F most commonly associated with?
It is most commonly associated with the LiftMaster MSWDCBB Mega Swing UL commercial-duty swing gate operator and related Mega Swing arm or enclosure parts diagrams.
Can SW22F be used as a universal swing gate part?
No. This is an OEM-style LiftMaster service part and should only be used where the operator parts diagram calls out the exact part number or assembly.
How should fitment be verified for SW22F?
Verify the operator model, compare the installed component, and check the Mega Swing parts diagram before ordering. Similar SW-prefix parts can look related but serve different functions.
What else should be inspected when replacing SW22F?
Inspect the surrounding arm, brackets, pivot hardware, bushings, fasteners, enclosure, and gate movement. A worn linkage or misaligned gate can damage a new part quickly.
