Microwave Turntable Roller Ring Drive Coupler for Panasonic (Genuine OEM)

We offer a genuine plastic drive coupler (clutch) designed to fit onto the shaft of the turntable stir motor. This small but critically important component connects the motor to the glass tray, ensuring smooth and even rotation of your food during cooking.

Technical Specifications

• Material: high-grade, heat-resistant engineering plastic (PPS/PBT) designed to withstand high temperatures and microwave radiation.

• Shaft Hole Shape: "D-shaped" (designed for a D-cut motor shaft).

• Top Configuration: 3-part cloverleaf "star" design for secure and stable glass tray fixation.

• Height: standard height profile for low-profile Panasonic turntables.

Full Model Compatibility

This coupler is a standard factory component for modern Panasonic ST series models, including:

• NN-ST25HB

• NN-ST27HM

• NN-ST34HM

• NN-ST34HW

• And other models utilizing a glass turntable tray with a 3-notch interlocking center.

When to Replace the Coupler

• Slipping / Jerky Motion: the motor runs and the shaft turns, but the glass tray remains stationary or rotates with jerky movements.

• Cracked Base: the D-shaped shaft hole has widened, stripped, or cracked, causing the coupler to wobble on the motor shaft.

• Melting: food particles or grease trapped underneath the coupler can cause arcing (sparking), leading to melted plastic and an unpleasant odor.

• Broken Fins: one or more of the star leaves have broken off, causing the tray to lose its stability.

Benefits of the Genuine OEM Part

• Perfect Fit: the genuine coupler fits snugly onto the shaft with zero play, preventing premature wear and tear on the motor's internal reduction gears.

• Food Safety: made of premium food-grade plastic that does not emit harmful chemicals or odors when heated.

• Grease-Resistant: the specialized material composition allows for easy cleaning and removal of food residue.
