Oil-Impregnated Bushing & Bearing Set for RC ERA C189 MD500 Helicopter

Quiet, Low-Friction Power Transmission

Worn-out bushings are the hidden cause of excessive flight noise and shortened motor life. These oil-impregnated (sintered) bushings are designed to replace gritty or dry bearings in the RC ERA C189, solving friction-related power loss and ensuring your transmission runs cooler and quieter during flight sessions. Ships worldwide.

Product Highlights

• Self-Lubricating Technology: The oil-impregnated metal structure slowly releases lubrication during use, reducing the need for frequent maintenance.

• Vibration Dampening: Sintered bushings offer excellent vibration absorption compared to standard ball bearings, leading to a smoother scale flight experience.

• High Wear Resistance: Engineered to handle the constant RPM of the main shaft and tail drive system without developing premature slop.

• Precision Sized: Specifically manufactured to the inner and outer diameters required for the C189 main frame and rotor housing.

Compatibility

For the RC ERA C189 Brushless RC Helicopter only.

What’s in the Box

• 1 x  Oil-Impregnated Bushing & Bearing Set

Install Tips

• Clean the Housing: Before pressing in the new bushings, ensure the plastic mounting holes in the fuselage or frame are free of old oil and dirt.

• Alignment is Key: Ensure the bushings are pressed in perfectly straight; an angled bushing will cause the main shaft to bind and could overheat the motor.

• Maintenance: While they are self-lubricating, a tiny drop of light machine oil every 20-30 flights will help maintain the "oil-cushion" and extend their service life.
