Overview

Marsh Brothers Aviation’s Flap Roller upgrade kit is a proactive solution that eliminates flap roller bearing seizure and minimizes wear of the aircraft flap tracks. By eliminating the roller greasing requirement via use of a self-lubricating bearing system, the rollers are maintenance-free by design thereby increasing the mean time between maintenance while reducing overall costs associated with replacement and repair of flap system components.

Benefits

• Reduces unscheduled maintenance downtime and expense.
• Eliminate the risks associated with bearing seizure and costs associated with flap track replacement.
• No hot/cold grease implications on bearing operation. Bearing is self-lubricating, requires no grease.
• Cartridge-type bearing design is highly resistant to incursion by dust/debris.
• Easy to install: Flange washers come preinstalled on the rollers, providing a drop-in solution that reduces the part count and eliminates the need to stack parts during assembly.

The bearing components are manufactured from AeroTough® GF, a proprietary engineered thermoplastic material which provides self-lubrication and can operate through a wide range of temperatures.
