- Purpose: Replacement turntable support ring for microwave ovens. Supports the glass tray and enables smooth rotation for even heating. - Material and durability: Made from durable, deformation-resistant plastic designed to withstand regular microwave use while maintaining shape and function. - Key function: The rolling support and bearing mechanism keeps the turntable rotating smoothly so food heats evenly, reducing cold spots and improving cooking consistency. - Design and fit: Slim, low‑profile ring that sits under the microwave tray without raising the plate noticeably. Designed as a direct replacement for standard rotating bases and turntable bearings. - Performance: Reliable rotation maintains even exposure to microwaves for better reheating, defrosting, and cooking performance compared with a stationary tray. - Ease of use: Simple to install and remove—place under the glass tray and test rotation. Wipe clean as needed for maintenance. - Why you need it: Replaces worn or broken support rings to restore proper turntable motion, extends the usable life of your microwave, and helps ensure consistent food temperature throughout reheating. - Practical applications: 1) Reheating leftovers so meals heat uniformly without cold spots. 2) Defrosting frozen food evenly by keeping the tray in continuous rotation. 3) Everyday family or office use to maintain reliable microwave performance after the original support ring wears out. - Compatibility note: Intended as a replacement support ring for standard microwave turntable systems and works with common rotating trays and bearings. Confirm physical fit with your existing glass tray before purchase. - What stands out: Combines sturdy, deformation-resistant plastic with a compact, unobtrusive design to restore stable, even rotation and improve microwave cooking results.
