The LiftMaster 15-80B60ZZZ Sprocket is a genuine replacement component engineered for heavy‑duty, chain‑drive LiftMaster commercial and industrial door operators. Identified by the 80B60T designation, this sprocket is built to mesh with ANSI #80 roller chain and features a 60‑tooth profile to transfer drive torque smoothly and reliably in trolley or jackshaft applications. Use it to restore proper operation in chain‑driven assemblies on sectional or rolling service doors when a worn or damaged sprocket is causing slippage, noise, or inconsistent travel.
As an OEM LiftMaster repair part, the 15-80B60ZZZ maintains factory geometry and fit for select operator models. The listing notation “80B60T, 3"B, 2‑3/4" x 10"” reflects the manufacturer’s sprocket and hub identification; verify exact fitment against your operator’s parts diagram or service manual before ordering. Installation should be performed by a qualified technician, with attention to shaft alignment, keying/set‑screw torque, and correct chain tension, and a chain guard in place. Follow all applicable safety practices, including lockout/tagout and UL 325 guidelines. This LiftMaster sprocket is ideal for maintenance teams and door professionals seeking a durable, OEM‑spec replacement part for commercial garage door operator repair.
