Liftmaster K12-2727, FLANGED BUSHING, 3/8"IDX5/8"
The LiftMaster K12-2727 is a flanged sleeve bushing used to support a smaller shaft, pivot, or rotating contact point inside select commercial gate operator assemblies. The 3/8 inch ID x 5/8 inch size helps keep the moving part centered while reducing metal-to-metal wear.
This bushing is commonly tied to select high-torque LiftMaster / Elite / OSCO swing gate operator applications, including CSW200 series references where the parts diagram confirms it. It is a small part, but a worn bushing can create sloppy movement, noise, poor alignment, and accelerated wear on the mating shaft or bracket.
Common Replacement Reasons
- Loose or sloppy pivot movement
- Worn shaft contact area
- Squeaking or grinding at a small bushing location
- Bushing flange is cracked, worn, or missing
- Service rebuild on a CSW-style swing gate operator

- Select Elite / OSCO industrial swing gate operator applications
- CSW200 series references where the parts diagram lists K12-2727 or 12-2727
Important Compatibility Notes
Confirm the installed location and original bushing dimensions. Similar 3/8 inch ID bushings may differ by outside diameter, flange diameter, thickness, or material.

Technician Note
If a bushing wears out quickly, look for a bent shaft, loose bracket, poor alignment, or missing hardware that is loading the bushing unevenly.
Before Ordering
- Match the manufacturer part number to the operator parts diagram before ordering.
- Compare the shaft, bearing, bushing, or gasket dimensions against the removed part.
- Check the operator model, series, and generation because similar LiftMaster mechanical parts may not interchange.
- Inspect nearby collars, sprockets, chains, keys, fasteners, and bushings for wear before reassembly.
- For commercial gate or barrier operators, have a qualified technician handle service if the gate movement is unsafe or the drive system is under load.
Professional Advisory
Commercial gate and barrier operator drive parts should be serviced with the gate secured, power disconnected according to the operator manual, and all safety devices left in proper working order. Do not bypass entrapment protection or operate a damaged gate system to test a mechanical repair.
