Liftmaster K12-4164, FLANGED BEARING
The LiftMaster K12-4164 is a self-aligning flanged bearing used in select LiftMaster gate operator mechanical assemblies. A self-aligning flanged bearing supports a rotating shaft while helping tolerate small alignment variations in the drive or support area.
This part is commonly connected with SL575 and SL585UL slide gate operator references, and some listings describe it for various LiftMaster slide and swing gate operators. Since bearing placement and shaft size can vary, confirm the operator parts diagram before treating it as a direct fit.
Common Replacement Reasons
- Bearing is noisy or rough
- Shaft support has looseness or wobble
- Flange bearing is worn, cracked, or corroded
- Drive shaft is not staying aligned
- Slide or swing gate operator mechanical assembly is being serviced

Technician Note
If a self-aligning bearing repeatedly loosens or fails, inspect the gate operator frame, shaft, collars, and chain tension. Bearing failure is often a symptom of misalignment elsewhere.
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.
