Improved material for extreme corrosion resistance
McFarlane replaces the original steel components with duplex stainless steel (even better than monel) components for a long life even in a harsh saltwater environment.

• Wear and vibration resistance for longer life
• No rust, even in salt water
• Costs less than the standard parts

Now improved with a Black Max™ nitrocarburized screw assembly to reduce friction and extend service life!

Ultra-precision bearing with no backlash

Improved Bearing
Precision bearing reduces free play and features extra low temperature grease for easy turning at low temperatures.

Improved Strength and Reliability
The original Cessna actuators use a 3/32" roll pin to attach the sprockets and retaining collars to the screw bars. These pins are critical as the front of the stabilizer would detach from the airframe if they failed. Although the original roll pins are technically strong enough, due to the nature of roll pins, they are prone to unpredictable failure. This is especially true if they are bent or damage during installation. To provide a more robust design, McFarlane redesigned the sprocket and retaining collar to allow the use of a 5/32" roll pin. This more than doubles the strength of the design. The screw and barrel are match machined for a precision fit.
