Eaton Char-Lynn Series 4000 motors are disc-valved hydraulic motors featuring an advanced Geroler™ (star-roller) design. They successfully integrate the power density of large motors into a more compact housing, capable of stably delivering high torque under continuous pressure. Their high-efficiency characteristics make them particularly suitable for industrial equipment sensitive to load and speed changes, serving as core power components for achieving precise and reliable transmission.

• Excellent Gerole star wheel roller mechanism: Unlike traditional gear or cycloidal motors, the core moving parts of the 4000 series adopt roller meshing, converting sliding friction into rolling friction. This results in lower internal wear, higher mechanical efficiency during startup and operation (which can be as high as 95% or more), and extremely smooth low-speed operation characteristics.
• Compact high-power density design: While maintaining the same torque output as the standard 4000 series, this series features a compact housing similar to the smaller 2000 series.This provides greater flexibility for equipment design, especially showing significant advantages inspace.constrained integration applications.
• Robust and reliable, suitable for harsh working conditions: The design can withstand high intermittent pressures and impact loads.Meanwhile, Eaton offers optional shaft seal protection components. This component, through a metal cover that rotates with the shaft, effectively prevents external contaminants such as dust and debris from invading the shaft seal area, significantly extending the service life under dusty and debris-laden working conditions.

With its compact, efficient, and high-torque characteristics, the 4000 series motor is an ideal choice for numerous industrial equipment:
• Material handling equipment: Drives belt conveyors, roller conveyor lines, and rotating mechanisms of packaging machinery.
• Engineering and construction machinery: Suitable for driving the traveling or working devices of equipment such as small excavators, skid steer loaders, and drilling machines.
• Special vehicles and equipment: Provides reliable power for street/industrial sweepers, harvesters, and mowers (such as waterway mowers).
• Industrial slewing drives: Used in the slewing mechanisms of mixers, rotary kilns, and tire cranes (crane).
