Dayton 5URA5 Brake Purpose

The Dayton 5URA5 is an end-mount disc brake rated at 6 ft-lb static torque for 56C motor flanges. It suits machine-shop equipment that requires reliable stopping and holding on a single-phase 115/208-230 V AC supply. Continuous-duty construction and a dripproof enclosure make it appropriate for industrial environments where moisture or splashing coolant may be present.

Upgrade From Lower Torque Units

This brake replaces smaller clutches or friction pads that can no longer hold the load at 1 hp and 3450 RPM or 1/2 hp at 1725 RPM. The jump is justified when the existing device overheats, slips under a 1.4 service factor, or cannot fit the 5/8 in shaft and 6.5 in outside diameter envelope. Maximum speed of 3,600 RPM sets the upper limit for the application.

Verify Shaft And Voltage First

Confirm the motor shaft measures exactly 5/8 in and that the flange matches the 56C pattern before ordering. Check that the site power provides 115 V or 208-230/460 V AC single phase to energise the coil correctly. Ensure the 4 in overall length clears adjacent components and that the dripproof rating satisfies the local environment.

Questions about this item

What motor flange does the 5/8 in shaft brake mount to?

The end-mount brake bolts to a 56C motor flange using the included hardware and instruction manual.

How do I wire the coil for 115 V or 208-230 V AC supply?

Connect the coil leads to the matching voltage taps; the brake is rated for 115/208-230 V AC coil voltage and 208-230/460 V AC operating voltage.

When should the friction disc be inspected or replaced?

Inspect the disc at each scheduled motor service; replace it when wear reduces the 6 ft-lb static torque below the 1.4 service factor requirement.
