Forked Roller Lever 1.5 in Arm
This Eaton forked roller lever is a metal actuator arm designed for limit-switch assemblies. It mounts on compatible Eaton E50AR16P or E50AR1 operators to convert rotary motion into a precise switching signal. Industrial maintenance technicians and machine builders select it when a durable front-mounted roller is required for cam or dog actuation.
Thermals noise and power draw
The component is a passive mechanical lever so it generates no heat, draws no electrical power and produces no audible noise during operation. Its all-metal construction resists deformation in ambient temperatures typical of factory floors. Friction at the roller interface remains low because both arm and roller are metal with a 0.75 in diameter and 0.32 in width.
Behaviour under sustained load
Under continuous cycling the lever maintains its 1.5 in arm length and 1.92 in by 2.87 in cross-section without measurable wear. The forked roller design distributes side loads evenly across the 0.75 in roller, preventing premature shaft deflection. It is not suited for applications requiring non-metallic rollers, adjustable arm lengths or rear-mounted roller positions.

Questions about this item
How is the E50KL544 forked roller lever installed onto the E50AR16P contactor, and what step is often missed?
The lever mounts to the actuator shaft of the E50AR16P; the step often missed is verifying the 1.5 in arm length and front roller position align with the application's travel before tightening the set screw.
What maintenance or replacement will the E50KL544 lever need over time?
The metal roller (0.75 in dia., 0.32 in wide) and forked arm pivot points should be inspected for wear; replace the lever if the roller develops flat spots or the arm shows fatigue cracking.
What is the first limit reached on the E50KL544 during sustained actuation cycles?
Mechanical wear at the roller-to-cam interface typically appears first, especially if side loading exceeds the 1.92 in arm width or 2.87 in depth design envelope.
