Dayton Adjustable Roller Lever Arm 1.5-4.05in Steel
Adjustable steel roller lever arm, 1.5 to 4.05 in, fits compatible Dayton limit switches
- TypeLight Switch
- Adjustable roller arm extends from 1.5 to 4.63 inches for flexible positioning
- Steel construction on both arm and roller resists wear in industrial environments
- Front-mounted 1.0 inch diameter roller ensures smooth actuation across travel
- Compatible with multiple Dayton limit switch models including 11X439 through 12T897
- 63 inch roller width and 1.19 inch arm width fit standard mounting configurations
Adjustable Roller Lever Arm
This Dayton lever arm fits a range of compatible limit switches with an adjustable steel roller actuator. The arm length spans from 1.50 in to 4.63 in, allowing precise positioning for mechanical actuation tasks. It mounts to the listed switch models using the front roller position. Steel construction provides durability in industrial environments.
Suitable For Direct Replacement
Installers replacing a worn actuator on Dayton switches 11X439, 11X440, 11X444, 11X446, 11X451, 11X454, 11X486 or the 12T835 through 12T897 series will find this part matches the original specifications. Buyers needing a different roller diameter, width or material should look at other actuator types. The fixed 1.0 in roller diameter and 0.63 in roller width cannot be altered.
Arm Length Adjustment Range
The critical specification is the adjustable arm length of 1.50 in to 4.63 in, which determines whether the actuator reaches the target mechanism. Verify the required throw distance against this range before ordering. The arm width of 1.19 in and depth of 1.25 in must also clear surrounding components.

Questions about this item
How do I install the adjustable roller lever arm on a compatible limit switch, and what step is often missed?
Mount the arm to the switch shaft using the 1.19 in arm width and 1.25 in arm depth, then set the roller position to front; the step often missed is adjusting the arm length between 1.50 in and 4.63 in before tightening.
What maintenance or replacement will this steel roller lever arm need over time?
The 1.0 in diameter steel roller and 0.63 in wide steel roller surface can wear from repeated actuation; inspect for flat spots or corrosion and replace the arm if the roller no longer rotates freely.
What is the first limit that appears under sustained use of this lever arm?
The adjustable arm length range of 1.5 in to 4.05 in defines the maximum mechanical throw; exceeding this travel will cause the roller to over-travel or bind against the switch body.
