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.

Whats 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.
